The meeting fully affirmed the implementation effectiveness of the breeding special program in 2022. With innovation as the fulcrum, the breeding special program has achieved the “acceleration” of seed industry revitalization, achieved “six breakthroughs”, and achieved the six improvement goals set since the 13th Five Year Plan: firstly, there have been breakthroughs in high-quality and efficient varieties. A total of 115 new varieties have been bred, including 35 approved by the state. After more than 10 years of breeding, the livestock and poultry cooperation team has developed the first new color otter rabbit variety in China, with significant economic benefits and leading production performance in the world. The sericulture cooperation group has bred the first new silkworm variety ‘Minghu Chunjiang’ in our province that has been approved by the state since 2000, with a 100 fold increase in the resistance index to blood type sepsis. The Drought Grain Collaborative Group has developed the first new sweet potato variety in China to resist basal rot, which has increased its resistance to the devastating disease of sweet potatoes by more than three times. On the basis of “South the Taihu Lake No.2” of Macrobrachium rosenbergii, the Fisheries Cooperation Group has bred the second national new variety of Macrobrachium rosenbergii, “South the Taihu Lake No.3”, which is in short supply of products. The established integrated commercial breeding model of Macrobrachium rosenbergii breeding and promotion has become a national model. Secondly, there has been a breakthrough in the level of breeding technology. Lead a rice breeding project, undertake 9 national major breeding projects (projects) such as rice, broccoli, and pine, and undertake several sub projects such as tomato and dry grain. Breeding technology and achievements have won 9 provincial and ministerial level scientific and technological awards, among which the early indica rice variety ‘Zhongjiazao 17′ has won the second prize of the National Science and Technology Progress Award, and the new varieties of silkworm and late japonica rice have won the first prize of the Zhejiang Province Science and Technology Progress Award. A number of technological breakthroughs from “0” to “1” have been formed. The first batch of frozen preserved somatic cell cloned Lanxi Huazhu pigs in China were born in Zhejiang. It is the second local pig breed obtained by cloning technology after Jinhua pig, and has great application prospects in the protection of local pig germplasm resources. Thirdly, there has been a breakthrough in the digitization of germplasm resources. Biological Breeding 4.0 Promote rapidly, carry out basic and technical research on biological breeding, speed up the digitization of germplasm resources, establish a digital utilization system for rice, vegetables, fruits, flowers, trees, upland crops and other genetic resources, and make significant progress in precise phenotypic identification technology, quality property evaluation model, genetic transformation and genome editing technology system. Fourth, there has been a breakthrough in technology to benefit people’s livelihoods. Promote and cultivate 236 varieties, with a demonstration and promotion area of over 2 million mu in the province. All conventional rice seeds and over 98% of hybrid rice seeds in our province come from specially bred varieties. Our province has developed 1/4 of the national leading rice varieties, ranking among the top in the country. The planting area of rapeseed varieties’ Zheyou 50 ‘and’ Zheyou 51 ‘ranks among the top three conventional varieties in China. The hybrid rapeseed variety’ Zheza 903 ‘is the first and only national grain and oil leading variety selected in our province and the Yangtze River Delta region. Our province has developed over 40% of the national market share for the Roche’s swamp shrimp, culter, and Chinese soft shelled turtle varieties, while the market share for the long haired rabbit and egg duck varieties is over 60% and 30%, respectively. Multiple high-quality varieties have achieved a win-win situation for both the public and scientific and technological personnel. The 2022 gross income from the transformation of cherry tomato variety ‘Zheyingfen 1’ exceeded 5.3 million yuan, the vegetable pea variety ‘Zhepi-3’ and ‘Zhepi-5’ were transferred for 5 million yuan, and the new white strawberry variety ‘Yuexueji’ was transferred for 1 million yuan to Jiande City. At the same time, we will optimize and strengthen seed industry enterprises, and cultivate 77 seed industry enterprises; Twelve national aquaculture seed industry enterprises were selected, ranking third in the country in terms of quantity. Fifth, breakthroughs have been made in the cultivation of breeding platforms. Approved as a national key laboratory for rice biological breeding, three key laboratories of the Ministry of Agriculture and Rural Affairs, including poultry and pigs (jointly built by various provinces), and the only provincial laboratory in the agricultural field – Xianghu Laboratory, has been established. Sixth, there have been breakthroughs in the construction of high-level talent teams. Through stable and sustained support from breeding programs, 179 people have been awarded national, provincial, and local talent titles, including 2 academicians in the field of rice. In 2022, 5 new talents including “National Ten Thousand Talents Plan Youth Top Talents” and “Science and Technology Innovation and Entrepreneurship Talents of the Ministry of Science and Technology” were added..Bilateral breakthroughs in key core technologies, and efforts in technological innovation and application promotion. Fourthly, we need to unite our efforts and accelerate the selection and breeding of new agricultural varieties to a new level. In 2023, in accordance with the work concept of “one overall goal, two annual tasks, and three more emphasis”, we will implement the two annual tasks of cultivating new varieties and promoting areas, continue to maintain the leading advantages in breeding in fields such as rice, aquatic products, tea trees, sericulture, vegetables, livestock and poultry, and forests, and promote more characteristic fields to reach international cutting-edge levels. Pay more attention to improving the systematicity and scientificity of breeding research, strengthen key core technology research, and accelerate the transformation from “experiential breeding” to “precision breeding”. Pay more attention to the development of the entire seed industry chain, regard quality and performance as the lifeline of breeding, cultivate good varieties that farmers are willing to grow and people like to eat, explore new commercial development models, accelerate the research and development of seed production and supporting technologies, promote the faster transformation of high-quality varieties on the ground and on the people’s dining table, so that the people and researchers can enjoy the “win-win” brought by technological dividends more timely. More emphasis is placed on the strategic strength of the seed industry and the systematic layout of innovation platforms, targeting the requirements of national platforms, national projects, national awards, and national talents, promoting the integrated development of education, technology, and talent in the breeding industry, and forming new breakthroughs at the national level.
The relevant leaders of the Provincial Department of Agriculture and Rural Affairs and the Provincial Forestry Bureau stated that they will continue to support the major scientific and technological special work for the selection of new agricultural varieties in the province during the 14th Five Year Plan period. Multiple departments will work together to promote the innovative development of the entire industrial chain of Zhejiang’s seed industry and promote its growth and strength.
