Seed coat – aleurone thickness is an important grain trait closely associated with bran yield and the accumulation of nutritionally valuable compounds, including lipids, γ-oryzanol, and vitamins. Therefore, this trait has considerable potential for rice breeding aimed at improving rice bran oil production and the nutritional quality of rice. The present study aimed to identify quantitative trait loci (QTLs) associated with seed coat-aleurone thickness using bulk segregation analysis (BSA). An F2 population consisting of 200 individuals was developed from a cross between the thick seed coat-aleurone line LO1050 and the moderately thick seed coat-aleurone cultivar Taichung65. A total of 1,381 SSR markers were screened for parental polymorphism, of which 90 polymorphic markers were selected for BSA. Two candidate QTLs associated with seed coat-aleurone thickness were identified: qAT4, located on the short arm of chromosome 4 near marker RM16262, and qAT7, located on the long arm of chromosome 7 near marker RM22144. The qAT7 locus is located on the same chromosome as previously reported QTLs controlling aleurone-related traits, whereas qAT4 may present a novel candidate region that warrants further validation through high-resolution QTL mapping. These findings provide valuable genetic information for further QTL mapping studies and marker-assisted breeding aimed at developing rice cultivars with increased bran yield.

Polygonum cuspidatum Sieb. et Zucc. is a medicinal herb rich in resveratrol and polydatin. Modern pharmacological studies have demonstrated that Polygonum cuspidatum Sieb. et Zucc. possesses a wide range of therapeutic properties, including lipid regulation, anti-inflammatory, antioxidant, anticancer, hepatoprotective, antiviral, antibacterial, antifungal, inhibition of melanogenesis and acceleration of wound healing. However, in vitro propagation of Polygonum cuspidatum Sieb. et Zucc. on semi-solid media has shown a relatively low shoot multiplication rate and remains limited to laboratory-scale production, making it difficult to generate sufficient plant material for practical applications. This study was conducted to evaluate the effects of temporary immersion system (TIS) culture conditions on the in vitro shoot proliferation of Polygonum cuspidatum Sieb. et Zucc. The ½ MS medium was supplemented with 2.5 mg L-1 benzyladenine combined with 0.2 mg L-1 indole-3-butyric acid and the temporary immersion system with six immersion cycles of 15 minutes each in 24 hours, 300 mL medium/Plantima resulted in the highest multiplication coefficient of shoots.

This study was carried out to breed the japonica variety with short grown duration, high yield, good quality and light pest-resistant for northern region of Vietnam. The VJ2 was developed from segregational populations, which have derived from VAAS16/J17 combination and selected by the pedigree method. VJ2 has a short grown duration, 125-130 days in the spring season, 104-108 days in the summer season. VJ2 has good characteristics such as average plant height, roll flat leaves and light diseases infection. In field trials, VJ2 has yield 6.89-8.14 tons/hectare in the spring season, 5.59-6.20 tons in summer season, oval grain, medium gelatinization temperature, low amylose content (15-16%) and good cooking quality. The results show that breeding through cross hybrid between japonica rice varieties and was selected by pedigree method, which can create new japonica rice variety has short grown duration, good quality, high yield and suitable cultivable with the conditions in northern Vietnam.

This study investigated the effects of Bacillus subtilis QST 713 and L-arginine supplemented from days 30 to 85 of gestation on various reproductive parameters in sows. A total of 164 sows were allocated to four experimental groups: a control group, a B. subtilis supplemented group (1010CFU), an L-arginine-supplemented group (20g), and a group receiving both B. subtilis (1010CFU) and L-arginine (20g). At farrowing, reproductive traits including total number of piglets born per litter, number of piglets born alive per litter, birth interval, farrowing duration, individual birth weight, total litter birth weight, within-litter birth-weight variation, proportion of piglets weighing ≤1.1 kg, proportion of piglets weighing >1.5 kg, stillbirth rate, mummification rate, and duration of postpartum vaginal discharge were recorded and compared among groups using linear mixed models or generalized linear mixed models. The results showed that, after adjustment for parity effects, supplementation with B. subtilis and/or L-arginine did not exert significant effects on any of the evaluated reproductive parameters. Further studies are warranted to evaluate the effects of these supplementation strategies on postnatal performance in order to obtain a more comprehensive assessment of their potential benefits.

Non-human primates are natural hosts of multiple malaria parasites, including species with zoonotic potential in Southeast Asia. This study aimed to detect and preliminarily characterize Plasmodium spp. in long-tailed macaques (Macaca fascicularis) from Cuc Phuong Forest, Ninh Binh province, Vietnam. In August 2024, blood samples from 11 macaques showing clinical signs suggestive of hemoparasitic infection were examined using Diff-Quik-stained blood smears and PCR assays. Of the 11 samples, 10 (90.91%) were positive for Plasmodium spp. Partial 18S rRNA gene sequencing of six representative samples showed high similarity to published Plasmodium inui sequences in GenBank. Co-detection of Anaplasma spp. and Rickettsia spp. was also observed in several macaques. These findings provide preliminary molecular evidence for the presence of P. inui in long-tailed macaques in Cuc Phuong Forest.

This study evaluated the effectiveness of a microbial product (EM-Su), developed by fermenting original EM with surimi processing by-products and supplemented with Bacillus strains, for the removal of total ammonia nitrogen (TAN) in freshwater. Two experiments were conducted to determine the effects of EM-Su dosage and initial TAN concentration on treatment efficiency. The results showed that TAN removal efficiency increased with increasing EM-Su dosage, with treatments of 5–9 mL/L achieving high efficiency without significant differences. Under optimal conditions (9 mL/L), EM-Su effectively removed TAN within the range of 0.5–10 mg/L, with the highest removal efficiency (79–95%) observed at TAN ≤ 5 mg/L after 24 h. At higher TAN concentrations (≥7.5 mg/L), the removal process tended to plateau after 16 h. Following nitrogen reloading, the microbial system maintained its treatment capacity, indicating good stability and adaptability of the product. Overall, EM-Su demonstrates high potential for application in water quality management in aquaculture systems, while also contributing to the valorization of surimi by-products within a circular economy framework. Further studies are required to evaluate its performance under practical pond conditions.

This study was conducted to describe demographic characteristics, assess knowledge, attitude and practice (KAP), evaluate the human–animal bond (HAB), and identify several barriers to dog and cat care in Hanoi. A descriptive cross-sectional survey was carried out from May to August 2025 on 302 dog and cat owners using a 41-item semi-structured questionnaire. The results showed that female respondents accounted for 58.9%, those aged 18–34 years represented 81.8%, and respondents with university education or higher accounted for 88.1%. Cat owners made up the largest proportion (55.6%), followed by dog owners (31.1%) and owners of both dogs and cats (13.2%). The proportion of correct answers was high for toxic foods (83.8%), harmful effects of obesity (80.5%), and the importance of vaccination (70.2%), but lower for regular deworming (40.4%) and routine health examination and screening in clinically healthy pets (30.8%). Most participants showed positive attitudes toward preventive care; however, practices remained limited. Only 38.4% had taken their pets for health examination within the previous 6–12 months, 33.4% fully complied with vaccination schedules, 21.9% used ectoparasite prevention regularly, and 62.6% had never provided oral hygiene care for their pets. Internet was the first source of information when pets developed health problems for 81.8% of respondents, whereas only 9.6% sought advice from veterinarians. HAB was relatively high, with 82.8% considering pets as family members. High care costs and conflicting online information were the two main barriers identified. The findings indicate that pet owners in Hanoi had positive attitudes and strong emotional attachment to their pets, but important gaps remained in preventive veterinary knowledge and practice.

This study applies remote sensing and Geographic Information Systems (GIS) to analyze land use/land cover (LULC) and land surface temperature (LST) dynamics in the peri-urban areas of Nghia Tru and Nhu Quynh (Hung Yen Province, Vietnam) during the period 2020–2025. Sentinel-2 imagery was used for LULC classification using the Gradient Tree Boost (GTB) algorithm, while LST was derived from Landsat data on the Google Earth Engine platform. The results indicate that built-up land increased by 652.30 ha, primarily converted from agricultural land and water bodies, accompanied by the expansion of high-temperature zones (≥45°C). The study also identifies the Heat Increase Index (HII) for different land cover transitions. The findings show that the conversion from water bodies to built-up land exhibits the highest HII value (8.12), followed by the transition from agricultural land to built-up land (7.85), while stable built-up areas also show a noticeable trend of thermal accumulation (5.46). These results provide a scientific basis for land use management and planning toward sustainable development, contributing to the mitigation of urban heat island effects in rapidly urbanizing peri-urban areas.

Nghiên cứu nhằm làm rõ đặc trưng phân bố theo mùa gió của nhiệt độ và độ muối vùng biển Quảng Nam, qua đó đánh giá vai trò chi phối của gió mùa, nguồn nước sông và địa hình đến cấu trúc thủy văn. Với dữ liệu được thu thập bằng thiết bị CTD tại các trạm vị vào hai mùa gió, sử dụng phương pháp thống kê và nội suy Kriging để xây dựng bản đồ phân bố và mặt cắt đứng.

Tầng đáy ngoài khơi xuất hiện khối nước lạnh và mặn, phản ánh cơ chế nước trồi ven bờ do vận chuyển Ekman, góp phần bổ sung dinh dưỡng, tăng năng suất sinh học và hình thành ngư trường tiềm năng. Kết quả nghiên cứu đã cung cấp cơ sở khoa học quan trọng cho dự báo ngư trường, quản lý tài nguyên biển và bảo tồn hệ sinh thái ven bờ Quảng Nam.

This study evaluated the variation of ambient air quality in Bac Ninh Province during the 2021–2025 period based on a dataset of 1,608 monitoring observations from 168 locations, combined with meteorological data. The results indicated that total suspended particles (TSP) and PM₁₀ were the dominant parameters governing air quality across the province, with effect sizes of η² = 0.115 and 0.080, respectively. Industrial cluster areas were identified as the most critical dust pollution hotspots, with 39% of monitoring periods falling into the poor AQI category. Source contribution analysis revealed that dust/particle emissions from industrial production and traffic activities were the major contributors to TSP (88.3%; R² = 0.88), combustion-related emissions were the dominant contributors to NO2 (117.3%; R² = 0.61), and incomplete combustion sources were the main contributors to CO (101.2%; R² = 0.99). Regarding temporal trends, only NO2 exhibited a statistically significant decreasing trend (τ = −0.500; p = 0.004; slope = −5.28 µg/m³/year), whereas TSP showed a significant negative correlation with relative humidity (ρ = −0.900; p = 0.037). Notably, the unfavorable meteorological conditions during the 2023 El Niño year reduced the differentiation among emission source groups, resulting in a phenomenon of “pollution homogenization” across the province.

This study optimized the culture medium for the endophytic bacterium Bacillus subtilis LV5-L1 to enhance its nitrogen-fixing activity in rice. Initial single-factor investigations revealed that cultivation time, pH, carbon source, starch concentration, and temperature significantly influenced nitrogen fixation capacity. Using the Plackett–Burman design for screening, pH and starch concentration were identified as the two most significant factors affecting NH4+ production. These variables were further optimized through Response Surface Methodology (RSM) with a Central Composite Design (CCD). The results established the optimal conditions at pH 7.0 and a starch concentration of 2 g/L. Under these conditions, the predicted NH4+ content was 54.965 mg/L, while experimental validation yielded 53.841 mg/L, demonstrating high model reliability. This research provides a technical foundation for developing high-quality microbial inoculants for sustainable agriculture.

Although consumer demand for fresh vegetables and fruits with high nutritional value, such as cherry tomatoes, has been increasing, studies on willingness to pay (WTP) and the factors influencing WTP for cherry tomatoes remain limited. This study aims to estimate consumers’ WTP for cherry tomatoes and identify the determinants of WTP among urban consumers in Vietnam. Based on data collected from 200 consumers, the payment card method was employed to estimate WTP, while an ordered logit regression model was applied to analyze the factors affecting WTP. The results indicate that the average WTP was approximately VND 37,000 per kilogram, with noticeable differences across urban areas and product attributes. Education level, food expenditure, concern for freshness, food safety, brand, knowledge of the health benefits of cherry tomatoes, and prior consumption experience positively influenced WTP, whereas age had a negative effect. In addition, consumers tended to be willing to pay higher prices for orange-colored and oval-shaped cherry tomatoes. The findings provide important policy implications for promoting product development and expanding the cherry tomato market in Vietnam.

This study assesses rice farming households’ perceived adaptive capacity to climate change, focusing on differences between small-scale farms (<2 ha) and large-scale farms (≥2 ha) in Hue City, Vietnam. Data were collected through four focus group discussions, 279 semi-structured household interviews, and relevant secondary sources. The findings show that both groups perceived their adaptive capacity to be high, with mean scores of 3.62 and 4.14, respectively. Large-scale farming households reported higher perceived adaptive capacity than small-scale households. This difference was primarily associated with human and physical capital, while differences in financial, social, and natural capital were not statistically significant. Human capital was the lowest-rated livelihood asset among small-scale households, particularly in terms of skills in applying modern technologies and adaptive farming techniques. The findings highlight the need to strengthen climate change knowledge, farming skills, and access to productive resources, particularly among small-scale rice farming households.

This study provides a comprehensive review of experiences in public investment for agricultural infrastructure development, with the aim of identifying key achievements and persistent constraints, thereby deriving policy-relevant lessons and proposing actionable implications for Hưng Yên Province. Drawing on a critical analysis of secondary data and published literature, the findings reveal that, despite contextual heterogeneity across countries, public investment in agricultural infrastructure consistently prioritizes irrigation systems and increasingly shifts toward high-tech infrastructure, underpinned by robust governance, monitoring, and accountability frameworks. Furthermore, many countries have established enabling policies and institutional arrangements to crowd in private sector participation, particularly by leveraging the catalytic role of public investment. Notwithstanding these advancements, several structural limitations remain evident, including fragmented and poorly coordinated investment, suboptimal efficiency, and infrastructure degradation that results in escalating maintenance costs. Considering these challenges, enhancing the effectiveness of public investment in agricultural infrastructure in Hưng Yên Province necessitates the formulation of a long-term public investment strategy, diversification of financing sources, acceleration of land consolidation processes, the establishment of rigorous procedures for project appraisal, approval, monitoring, and disbursement, and the promotion of inclusive participation from local stakeholders and communities.

This research analyzed the current situation of state management of household business activities at night markets in Hoan Kiem Ward, Hanoi City. A total of 70 business households operating in various sectors, 50 residents and tourists surveyed through questionnaires, and 15 officials from state management agencies were interviewed. The research findings indicate that 85.7% of business households demonstrated good compliance with regulations on the origin and traceability of goods. Environmental regulations and food safety and hygiene standards were strictly implemented, with over 90% of busine households meeting the required standards. Although the qualifications and competencies of management officials adequately met practical demands (accounting for 87.1%), together with the flexible coordination among relevant authorities contributing to maintaining a stable, safe, and civilized business environment, several business households still failed to comply fully with regulations on tax management (7%), food safety and hygiene (8.6%), and fire prevention and fighting (4.3%). Based on these findings, the study proposes several recommendations to enhance state management of household business activities in the research area.

Khí hậu và thiên tai đang đặt ra những thách thức đối với sản xuất nông nghiệp tại Việt Nam. Nghiên cứu này phân tích mối liên kết động giữa khí hậu (nhiệt độ tối đa, lượng mưa), thiên tai và giá trị gia tăng nông nghiệp tại Việt Nam giai đoạn 1985–2023, áp dụng phương pháp Liên kết động (Dynamic Connectedness - DC) và Liên kết động chung mở rộng (Extended Joint Connectedness  - EJC). Kết quả cho thấy chỉ số liên kết động tổng thể trung bình đạt 32,93% (DC) và 41,96% (EJC); nhiệt độ tối đa là biến phát lan tỏa ròng lớn nhất, trong khi giá trị gia tăng nông nghiệp là biến tiếp nhận ròng lớn nhất. Hệ thống có sự thay đổi cấu trúc rõ rệt: lan tỏa rất mạnh trong giai đoạn 1985–2000 và giảm, giữ ổn định ở mức 28–38% từ năm 2000 đến nay, phản ánh mức độ tổn thương của nông nghiệp trước cú sốc khí hậu đã được thu hẹp. Trên cơ sở đó, nghiên cứu đề xuất ưu tiên giải pháp thích ứng với các yếu tố khí hậu và tái cơ cấu nông nghiệp theo hướng giá trị gia tăng.  

Literature review shows that measures to reduce greenhouse gas emissions are divided into four main groups: (i) nutritional management for ruminant animals through diet adjustment, supplementation with CH₄ production-inhibiting additives, and supplementation with microorganisms and micronutrients; (ii) waste management using biogas tanks, composting, bio-pads, and manure separation technology; (iii) sustainable pasture management to increase CO2 storage in the soil, helping to reduce greenhouse gases from livestock grazing activities; (iv) application of energy-saving technology and the use of renewable energy. Implications to promote the application of greenhouse gas mitigation measures in livestock farming in Vietnam include: planning towards concentrated livestock farming to improve waste management efficiency and economic efficiency; raising awareness among livestock owners and management staff, disseminating and training livestock owners on greenhouse gas mitigation measures; investing in research and development of products to improve animal nutrition, livestock waste treatment technology, energy-saving technology, and renewable energy production; providing financial support for livestock owners to invest in emission reduction measures; and promoting the operation of the carbon credit market to create additional financial incentives for livestock owners to reduce greenhouse gases.

Trong bối cảnh công nghiệp hóa và hội nhập kinh tế quốc tế, mối quan hệ giữa tăng trưởng và chất lượng môi trường tại Việt Nam ngày càng phức tạp. Nghiên cứu này phân tích cơ chế và mức độ liên kết động giữa tăng trưởng kinh tế, độ mở thương mại, sản xuất công nghiệp và dấu chân sinh thái tại Việt Nam giai đoạn 1986–2024. Phương pháp Liên kết động (DC) và Liên kết động chung mở rộng (EJC) được áp dụng để đánh giá sự thay đổi của các lan tỏa này theo thời gian. Kết quả cho thấy các biến trong mô hình duy trì mức liên kết tổng thể tương đối cao (50–65%), tăng mạnh trong giai đoạn công nghiệp hóa và hội nhập, phản ánh sự liên kết chặt chẽ giữa hoạt động kinh tế và dấu chân sinh thái. Sản xuất công nghiệp là yếu tố lan tỏa lớn nhất (đặc biệt từ 1990 đến 2005), độ mở thương mại đóng vai trò thứ cấp từ đầu những năm 2000, trong khi tăng trưởng kinh tế và dấu chân sinh thái đều là biến nhận lan tỏa - riêng dấu chân sinh thái nhận lan tỏa lớn nhất từ các biến khác trong hệ thống. Sự nhất quán giữa DC và EJC khẳng định độ tin cậy của kết quả, đồng thời hàm ý rằng giảm tiêu hao tài nguyên trong sản xuất công nghiệp và lồng ghép tiêu chuẩn môi trường vào chính sách thương mại là ưu tiên cấp thiết để hạn chế gia tăng dấu chân sinh thái tại Việt Nam.

Sinh kế ven biển hiện đang đối mặt với nhiều thách thức như suy giảm nguồn lợi thủy sản, biến đổi khí hậu và chi phí sản xuất gia tăng. Nghiên cứu nhằm phân tích thực trạng sinh kế và các yếu tố ảnh hưởng đến thu nhập của hộ gia đình ven biển tỉnh Gia Lai. Nghiên cứu sử dụng khung sinh kế DFID–IFAD kết hợp khảo sát 480 hộ gia đình tại bốn địa bàn gồm An Lương, Cát Tiến, Đề Gi và Quy Nhơn Đông. Dữ liệu được xử lý bằng thống kê mô tả, hồi quy tuyến tính OLS và phân tích đa tiêu chí (MCA). Kết quả nghiên cứu cho thấy sinh kế ven biển hiện vẫn phụ thuộc lớn vào khai thác thủy sản, mặc dù cơ cấu sinh kế đang có xu hướng đa dạng hóa nhằm thích ứng với rủi ro nghề biển ngày càng gia tăng. Đánh bắt thủy sản vẫn là nguồn thu nhập chi phối lớn nhất của nhiều hộ gia đình, trong khi các hoạt động nông nghiệp, nuôi trồng thủy sản và dịch vụ ngày càng đóng vai trò quan trọng hơn. Chính vì vậy, việc hỗ trợ đa dạng hóa sinh kế và nâng cao năng lực thích ứng được xem là định hướng quan trọng nhằm giảm mức độ dễ bị tổn thương và cải thiện sinh kế của hộ ven biển tỉnh Gia Lai

The study analyzes the current situation and  impact of digital human capital (DHC) on vegetable farmers' income in Phuc Loc, Hanoi. Using a Log-Linear model on 100 households, results indicate that DHC is a key factor, increasing income by 10.3% per unit index increase. Digital skills help farmers reduce information asymmetry and optimize production costs,. The paper proposes strengthening practical digital skills training to sustainably enhance farming households' income within the digital economy.

The study was conducted to determine the influence of internal factors on improving the quality of human resources in garment enterprises in Ninh Binh Province in the context of the Fourth Industrial Revolution. In addition to secondary data, the study surveyed 300 respondents, including 100 managers and 200 workers from 100 garment enterprises in the province. Descriptive statistics and the PLS-SEM model were used to analyze the data. The research results show that technological factors, employee-related factors, and enterprise-related factors all have positive effects on improving the quality of human resources in garment enterprises, with impact coefficients of 0.593, 0.264, and 0.237, respectively. Based on these findings, the study proposes several key solutions to improve the quality of human resources in garment enterprises in Ninh Binh Province in the coming period

This study aims to analyze the current situation and assess the factors influencing human resource development in agricultural cooperatives in the context of digital transformation, focusing on the Eastern area of Hanoi (a case study in Gia Lam). Primary data were collected through a survey of 90 cooperative managers, members, and workers, combined with secondary data from relevant authorities. Descriptive statistics, comparative analysis, and synthesis methods were employed to assess training activities, workforce qualifications, managerial capacity, policy mechanisms, and the level of digital technology adoption. The results indicate that the quality of human resources in cooperatives has improved in terms of education, skills, and access to digital technologies. Training and capacity-building activities have been increasingly emphasized, contributing to enhanced production and business performance. However, a gap remains between training and practical application, and the level of digital transformation varies significantly across cooperatives.Based on these findings, the study suggests strengthening practice-oriented training, improving managerial capacity, enhancing policy support mechanisms, and investing in digital infrastructure to promote sustainable human resource development in agricultural cooperatives under digital transformation. Key words: Human resources; agricultural cooperatives; digital transformation.

The study analyzes factors influencing the adoption of sustainable agricultural practices (SAPs) among vegetable farming households in Nam Thanh Mien commune, Hai Phong city. Data were collected from 150 households through structured face-to-face interviews and analyzed using a Logit model, in which a household is considered an adopter when it implements a certain number of SAPs. The results show that institutional and technical support factors play a decisive role, particularly participation in training, access to extension services, credit, and production–market linkages, all of which have positive and statistically significant effects. In addition, education level and farm size increase the likelihood of SAP adoption, while the number of plots and farming experience tend to reduce it. In contrast, demographic characteristics such as gender, age, and labor are not statistically significant when other factors are controlled for. The findings highlight the dominant role of institutional systems and support services in promoting the transition toward sustainable agriculture.

Migration is a major strategy helping households manage risk. However, the existing literature continues to debate whether migration and remittances primarily protect basic consumption levels or finance long-term capacity-enhancing investments (such as education or healthcare). This paper addresses this issue by analyzing the impact of migration on both the level and structure of household expenditure in rural Vietnam. Utilizing 2022 survey data from 1,227 households in Ha Tinh and Dak Lak, this study applies Ordinary Least Squares models with commune fixed effects, coupled with Propensity Score Matching and doubly robust estimators for robustness checks. The results indicate that households with migrants exhibit a 12–14% higher total expenditure. Notably, these additional resources are primarily allocated towards education and healthcare, whereas the impact on food expenditure is insignificant. These findings reinforce the New Economics of Labor Migration theory, confirming that migration provides financing for investments that yield long-term developmental returns.

This study was conducted to identify the factors influencing the adoption of digital technology among farming households in Chuong My Ward, Hanoi City. In addition to secondary data, primary data were collected through a survey of 120 households. A logit model was used to estimate the effects of various factors on households’ adoption of digital technologies in agriculture. The estimated results indicate that most variables included in the model are significant in explaining households’ decisions to adopt digital technologies, including age, academic level, income, land size, participation in agricultural extension training programs, and membership in cooperatives. Among these factors, participation in agricultural extension training has the strongest influence on the adoption of digital technologies in agriculture. Based on these findings, the study proposes several recommendations to promote the adoption of digital technologies among farming households in Chuong My Ward in the coming period.

Bicolor supersweet corn is a premium fresh-market maize valued for the attractive mix of yellow and white kernels combined with intense sweetness. Breeding bicolor cultivars is demanding because it must combine three trait groups with distinct genetic control: kernel colour, sweetness and eating tenderness. This review synthesises the genetic basis and breeding strategies for this crop. Yellow endosperm colour is governed by the Y1 locus encoding phytoene synthase and is fully dominant over white, whereas aleurone colour is controlled by a separate anthocyanin pathway. Because the endosperm is a triploid tissue formed by double fertilisation, colour and sweetness are expressed immediately on the maternal ear according to the pollen genotype, a phenomenon termed xenia; consequently the heterozygous Yy F1 hybrid bears an ear segregating yellow and white kernels at about 3:1. High sweetness in supersweet corn results from the recessive sh2 gene, with bt2, which reduces endosperm starch synthesis; contamination by other endosperm types such as su1 or se1 can abolish sweetness through xenia, so genotype uniformity or spatial isolation is required. General and specific combining ability, estimated by Line×Tester or diallel mating designs, indicate whether additive effects should be exploited through line selection or non-additive effects through direct hybrid evaluation. Pericarp thickness, the main determinant of tenderness, is a heritable polygenic trait improvable by line selection. Together these principles provide a framework for the domestic breeding of bicolor supersweet corn.

Innovation and digital transformation are recognized as two key drivers that enhance managerial effectiveness, competitiveness, and organizational adaptability in the digital economy. However, existing studies have largely examined these concepts separately, while the mechanisms underlying their interaction and integration, particularly in small and medium-sized enterprises (SMEs), remain insufficiently explored. Using a systematic literature review approach, this study analyzes the theoretical foundations of innovation theory, dynamic capabilities theory, and the Technology–Organization–Environment (TOE) framework, while synthesizing relevant empirical evidence. The findings indicate that digital transformation provides the technological and data infrastructure that fosters innovation through enhanced connectivity, organizational learning, and business model innovation. Conversely, innovation serves as a mechanism for transforming digital resources into business value and managerial effectiveness. Based on these insights, the study proposes an integrated framework for innovation and digital transformation in business management, in which digital transformation functions as the technological driver, innovation acts as the value-creation mechanism, and dynamic capabilities provide the foundation for effectively leveraging the synergy between these two elements. The proposed framework contributes to the advancement of theoretical understanding and offers directions for future empirical research.

The article systematizes the theoretical foundations of green jobs in the tourism sector and analyzes international experiences to derive policy lessons for Vietnam. The study employs document analysis and policy comparison methods through three representative cases: the European Union, Thailand, and South Korea. The findings indicate that the EU has relatively comprehensive institutional and financial frameworks for developing green jobs, although community participation remains uneven. Thailand stands out for its community-based tourism model and high level of social inclusiveness, yet the depth of green skills among workers is still limited. Meanwhile, South Korea leads in technology application and ESG governance in tourism but needs to strengthen community inclusiveness. In Vietnam, despite the tourism sector’s potential to generate approximately 10.5 million jobs by 2030, green jobs currently account for only a small proportion of total tourism employment. Key challenges include legal and policy gaps, shortages of green skills, and limited financial support mechanisms. Based on these findings, the article proposes several policy recommendations, including improving the legal framework, integrating green skills into vocational training systems, promoting certified community-based tourism models, and strengthening public–private partnerships to support sustainable green tourism development.
