Unfortu-nately, wheat is considered as a recalcitrant plant to genetic transformation due to its low efficiency and genotype depend-ency. To overcome these problems, various transformation methods such as biolistic bombardment, Agrobacterium tumefa-ciens , pollen-tube pathway, ion implantation, laser microbeams puncture, treatment with polyethylene glycol and ultrasonic wave, and electroporation have been reported in wheat using various types of explants including immature embryos, mature embryos, anthers derived calluses, inflorescences, apical meristems, and other floral organs. In this review, several major transformation approaches and their applications in wheat are reviewed, and potential strategies for the development of safe transgenic wheat plants are discussed. The objective of this review is to provide an update on current status of wheat trans-formation, and to stimulate further research for improving transformation efficiency in wheat.Keywords: wheat; genetic transformation小麦是世界上重要的粮食作物之一, 与社会经济发展、粮食安全供给和人类营养健康密切相关。

In this study, we report a new winter wheat cultivar,ND1108, developed by the researchers at China Agricultural University. The ND1108 cultivar is characterized by high yield potential, disease resistance, and high baking quality. This study aimed to investigate the agronomical and quality traits of ND1108 under different conditions, and to evaluate its overall performance in comparison with existing winter wheat cultivars.Introduction:China is the world's largest wheat producer, and wheat is one of the most important cereal crops in the country. However, the wheat production in China is threatened by various pests and diseases, which often lead to significant yield losses. In recent years, Chinese researchers have focused on developing high-yielding, disease-resistant wheat cultivars for sustainable wheat production. Methods:The ND1108 cultivar was developed by crossing the Jingdongmai and Linyoumai parents, and was selected through several rounds of field trials and laboratory analyses. The agronomic traits ofND1108, including plant height, days to heading, thousand grain weight, yield per hectare, and disease resistance were evaluated under field conditions in six different locations in China. Thebaking quality of the wheat flour was assessed using the Farinograph and the Mixograph tests.Results:The ND1108 cultivar exhibited excellent agronomic traits, including high yield potential (yield range of 7.55 to 10.39 t/ha), good resistance to wheat stripe rust and powdery mildew, and moderate resistance to Fusarium head blight. The cultivar also had a moderate plant height (80-90 cm) and a medium thousand grain weight (40-45 g). The Farinograph and Mixograph tests showed that ND1108 had good baking quality, with a higher water absorption capacity, slower dough development time, and a higher dough strength than the control cultivars.Conclusion:The ND1108 winter wheat cultivar is a high-yielding, disease-resistant cultivar with good baking quality. It offers potential benefits to farmers and the wheat industry in China. The study highlights the importance of breeding new wheat varieties that not only have high yield potential and disease resistance but also meet the quality requirements of the wheat industry. Ongoing research and development are needed to ensure the sustainable production of wheat in China.The development and release of ND1108 cultivar is a significant achievement in the breeding of winter wheat in China. This cultivar brings a new option for farmers to achieve high productivity and quality in wheat production, while reducing the risk of disease and pest damage.Among the agronomic traits evaluated, the high yield potential of ND1108 is particularly noteworthy. In different regions of China, the yield of ND1108 ranges from 7.55 to 10.39 t/ha, which is higher than the average yield of many common cultivars. The good disease resistance of ND1108 to stripe rust and powdery mildew is also a valuable trait, as these two diseases can cause severe yield losses in many wheat-growing areas of China.The moderate resistance of ND1108 to Fusarium head blight is also encouraging, as this disease has become more prevalent in recent years due to changing weather conditions and farming practices. The moderate plant height and medium thousand grain weight of ND1108 make it suitable for different planting densities, which can further optimize its yield potential and adaptation to various environments.The baking quality of ND1108 is another highlight of this study. The Farinograph and Mixograph tests showed that ND1108 has a higher water absorption capacity, slower dough development time, and a higher dough strength than the control cultivars. This indicates that ND1108 can produce dough with better texture and elasticity, which meets the quality requirements of many processed wheat products.In conclusion, the ND1108 winter wheat cultivar developed by Chinese researchers is a promising new option for wheat production in China. Its combination of high yield potential, disease resistance, and good baking quality makes it a valuable addition to the existing cultivars. The results of this study also demonstrate the importance of continuous breeding efforts toimprove the sustainability and competitiveness of the wheat industry in China.Furthermore, the development of ND1108 cultivar is significant in terms of its potential economic benefits for farmers and wheat industry. High yielding cultivars with good disease resistance can not only increase farmers’ income, but also contribute to food security and stability in the wheat market. Moreover, the good baking quality of ND1108 can enhance the competitiveness of wheat products in domestic and international markets. This cultivar can be an attractive option for flour mills and bakeries, as it can produce high-quality flour and bread while reducing production costs.However, it is important to note that the widespread adoption of ND1108 and other improved cultivars requires continuous efforts in supporting research, extension, and education programs. These programs can help farmers and extension agents to access information and technologies related to crop management, pest and disease control, and quality assessment. They can also facilitate the transfer and adoption of new cultivars and farming systems, and promote collaboration among different stakeholders in the wheat industry.In conclusion, the development and release of ND1108 winter wheat cultivar in China is a significant achievement that reflects the ongoing efforts of researchers and policy-makers to address the challenges facing the wheat industry. This cultivar can contribute to sustainable and profitable wheat production, while meeting the demands of consumers for safe, nutritious, and high-quality wheat products. Its success also highlights the importance of innovation, cooperation, and capacity building in promoting the developmentand transformation of agriculture in China and beyond.Apart from the economic benefits, ND1108 cultivar can also have environmental advantages. Its high yield potential and good disease resistance can reduce the need for pesticides and fertilizers, which can ultimately lower the environmental impact of wheat cultivation. It can also improve soil health and fertility by reducing tillage, improving water infiltration, and increasing organic matter content.In addition, the development of ND1108 reflects the growing importance of scientific research and innovation in modern agriculture. China has been investing heavily in agricultural research and development, and has made significant progress in breeding new cultivars, improving crop management practices, and applying new technologies. This has contributed to China's food security and self-sufficiency, and has also opened up new opportunities for international cooperation and collaboration.However, there are also challenges and risks associated with the adoption of new cultivars and farming practices. The introduction of ND1108 and other high-yielding cultivars can lead to monoculture and loss of genetic diversity, which can increase the vulnerability of crops to pests, diseases, and climate change. It can also raise concerns about the safety and quality of food products, especially if they are genetically modified or have high pesticide residues.To address these challenges, it is important to ensure that the development and adoption of new cultivars and farming practices are based on sound scientific evidence, rigorous testing, andeffective regulation. It is also crucial to promote sustainable and diversified agricultural systems that prioritize the conservation of natural resources, protect biodiversity, and enhance the resilience of crops and ecosystems.Therefore, the development of ND1108 winter wheat cultivar represents a major step forward for the Chinese agriculture industry, but also underscores the need for continued investment in research, education, and policy initiatives that can promote sustainable and inclusive growth in the sector.In addition to the importance of sustainable and diversified agricultural systems, it is also crucial to involve farmers and local communities in the development and adoption of new farming practices and technologies. Farmers' knowledge and experiences can be valuable in identifying the most pressing challenges and opportunities in their local contexts, and in developing and adapting appropriate solutions.Furthermore, promoting innovation in agriculture requires a multidisciplinary approach that involves not only scientists and researchers, but also policymakers, extension agents, and private sector actors. It is important to foster partnerships and collaboration among stakeholders from different sectors and disciplines, and to support the dissemination of research findings and practical knowledge through training and outreach programs. In the case of the ND1108 cultivar, it is also important to promote responsible use and management of the new variety, including monitoring and evaluation of its performance and impact on farmers' livelihoods and the environment. This can help identifypotential risks and opportunities associated with its adoption, and inform future breeding and research efforts.In summary, the development of ND1108 winter wheat cultivar represents a significant achievement for the Chinese agriculture industry, but also highlights the importance of promoting sustainable and inclusive growth in the sector. This requires a comprehensive approach that addresses the social, economic, and environmental aspects of agriculture, and involves all relevant stakeholders in the development and implementation of new farming practices and technologies.Moreover, the global food system faces several challenges such as climate change, population growth, and increasing demand for food. It is crucial to develop sustainable and resilient food systems to ensure food security for all. The ND1108 cultivar has the potential to contribute to sustainable food production by increasing yield and reducing pesticide use, and its successful adoption can serve as a model for other regions and crops.However, the adoption of new technologies and practices is not always easy, and there may be social, cultural, and economic barriers to their implementation. For instance, small-scale farmers may lack access to credit, markets, and information, which can hinder their ability to invest in new technologies or adopt new practices. Therefore, it is important to address these challenges through policies and programs that support innovation, entrepreneurship, and inclusive growth.In particular, rural development strategies should focus on creating an enabling environment for innovation and entrepreneurship byproviding access to land, water, and other resources, as well as financing, training, and technical support. Such strategies can also help promote sustainable agricultural practices by encouraging diversification, conservation, and ecological intensification.In conclusion, the development of the ND1108 winter wheat cultivar represents a significant milestone in Chinese agriculture, and highlights the importance of sustainable and inclusive growth in the sector. By promoting innovation, collaboration, and responsible use of new technologies and practices, we can not only increase food production and improve farmers' livelihoods, but also ensure the long-term sustainability and resilience of the global food system.One way to promote sustainable and inclusive growth in agriculture is through the development and promotion of agroecological approaches. Agroecology is the study of ecological processes in agricultural systems and emphasizes the integration of social, economic, and environmental dimensions. Agroecological approaches promote biodiversity, reduce the use of synthetic inputs, and enhance the resilience of agroecosystems to climate change and other stresses.Agroecological approaches also promote social and economic inclusion by empowering small-scale farmers, women, and marginalized groups to participate in sustainable agriculture. By shifting the focus from maximizing yields to promoting ecological function and social equity, agroecology can help create more just and sustainable food systems.Furthermore, policies and programs that promote agroecological approaches can also help reduce the negative environmentalimpacts of agriculture, such as soil degradation, water pollution, and greenhouse gas emissions. Sustainable intensification, which refers to increasing food production per unit area while minimizing negative environmental impacts, can be achieved through a combination of agroecological approaches and improved technologies and practices.In conclusion, the development of the ND1108 winter wheat cultivar is a promising step towards sustainable and inclusive growth in Chinese agriculture. However, sustainable and inclusive growth in agriculture requires a systemic approach that addresses social, economic, and environmental dimensions. Agroecology and sustainable intensification offer promising pathways towards more resilient and equitable food systems, but their success will depend on the adoption of supportive policies, programs, and institutions.In addition to agroecology and sustainable intensification, other strategies can also promote sustainable and inclusive growth in agriculture. These include supporting small-scale farmers through access to credit, input supplies, and markets. It is important to ensure that small-scale farmers are included in the value chain and receive fair prices for their products.Investing in research and development for agricultural technologies that are climate-smart, resource-efficient, and sustainable can also be a game-changer. This includes breeding crop varieties that are more resilient to climate change, developing agroforestry systems that promote biodiversity and soil health, and promoting sustainable approaches to livestock production.Lastly, creating an enabling policy environment is crucial forpromoting sustainable and inclusive growth in agriculture. This includes policies that support agroecological practices, promote sustainable intensification, and incentivize the adoption of climate-smart technologies. In addition, policies that promote gender equality, address land tenure issues, and ensure equitable access to resources are also important for creating inclusive agricultural systems.In conclusion, sustainable and inclusive growth in agriculture requires a holistic and integrated approach that addresses social, economic, and environmental dimensions. It is possible to achieve food security while promoting sustainability and equity, but it will require concerted efforts from governments, civil society, and the private sector. By adopting sustainable agricultural practices and empowering small-scale farmers, we can create more resilient and just food systems that benefit both people and the planet.Another key aspect of promoting sustainable and inclusive growth in agriculture is improving food distribution and reducing food waste. According to the United Nations, about one-third of all food produced globally is lost or wasted, which not only exacerbates food insecurity but also increases greenhouse gas emissions through the production and disposal of wasted food. Addressing food waste will require collaboration across the food supply chain, from reducing post-harvest loss on farms to improving food storage and transportation infrastructure.Additionally, promoting sustainable agriculture can have positive ripple effects beyond the farming sector, including job creation in rural areas and the development of local economies. By empowering small-scale farmers, creating sustainable value chainsand investing in rural infrastructure, agriculture can also contribute to poverty reduction and overall economic growth.Finally, education and awareness-raising are essential for promoting sustainable and inclusive agriculture. This includes educating farmers on sustainable farming techniques, training extension workers to disseminate information, and raising consumer awareness about the benefits of sustainable food systems. Education can also play a role in promoting gender equality in agriculture, by ensuring that women have equal access to education and training opportunities.Overall, promoting sustainable and inclusive growth in agriculture is a complex process that requires addressing social, economic, and environmental factors. However, by adopting a holistic approach and investing in sustainable practices and policies, we can create more resilient, equitable, and sustainable food systems for current and future generations.。
