These scientific research achievements have achieved remarkable economic and social benefits. 1. During my work in Baicheng Academy of Agricultural Sciences, I presided over three key projects of the Municipal Science and Technology Commission (1) "Maize Hybrid Breeding in Semi-arid Area of Western Jilin Province" (2) "High-oil Maize Hybrid Breeding" (3) "Middle Sorghum Hybrid Breeding". In February and June, 1998, 1 1 were transferred to the corn research institute of Jilin Academy of Agricultural Sciences to engage in special corn breeding. A total of 203 waxy corn materials were introduced, and s 1-S6 846 waxy corn progeny lines were selected. Two waxy corn populations were established and 237 waxy corn progeny materials were backcrossed. Two excellent combinations were selected. At present, he is the deputy director of the research office of maize variety resources and evaluation, and is in charge of the basic work sub-project of the Ministry of Science and Technology "Collection, Preservation and Arrangement of Maize Germplasm Resources". 786 copies of maize resources were popularized and updated, and 35 copies were put into the national medium-term database. Participated in national and provincial projects 10, of which 1, the project of "Jilin Province Agricultural Comprehensive Development High-quality Feed Grain Base Construction", ranked third; 2. The national "863" project "Research on Breeding and Industrialization Technology of New Varieties of High Oil Corn" won the third place; 3, "Ninth Five-Year Plan" national key scientific and technological research project "Research on deep processing and development of special corn", fourth place; 4. Jilin Provincial Science and Technology Department's major project "Research on Standardized Production Technology of Special Corn", 4th place; 5. National "863" Project "Insect-resistant Transgenic Corn", 4th place; 6. The fifth place of the Achievement Transformation Fund Project of the Ministry of Science and Technology "Regional Test and Demonstration of High-quality Special Maize Varieties". Published more than 20 academic papers. Among them, the first author's articles exceed 10.
