On this day 120 years ago, on February 12, 1905 (January 9, 1905 in the lunar calendar), agricultural educator and maize geneticist Wu Shaojing was born. Wu Shaojing (1905-1998), agricultural educator, maize geneticist and breeder. A native of Jiashan County, Anhui Province. Graduated from the Department of Agronomy, College of Agriculture, Jinling University in 1929. He studied at the College of Agriculture, University of Minnesota in the United States from 1934 to 1938 and obtained a doctorate. After returning to China in 1938, he served as a professor at the College of Agriculture, Guangxi University and the College of Agriculture, Jinling University; Technical Commissioner of the Agricultural Improvement Institute of Guizhou Province. After 1949, he served as vice president of Henan Agricultural College; director of the Chinese Agricultural Society, the Chinese Crop Society, and the Chinese Genetics Society; member of the Academic Committee of the Chinese Academy of Agricultural Sciences; member of the Science and Technology Committee of the Ministry of Agriculture, Animal Husbandry and Fisheries; representative of the 3rd to 6th National People's Congress; honorary president and first-class professor of Henan Agricultural University; deputy director of the Standing Committee of the Henan Provincial People's Congress. He has been engaged in the research of corn varieties for a long time and has made outstanding contributions to the development of corn production in our country. The article "The Relationship between the Blood Relation of Maize Inbred Lines and the Performance of Hybrid Combinations", which was developed in the Journal of the American Society of Agronomy in 1939, proposed that inbred lines from different sources have greater hybridization advantages than interbred lines with close relatives. This In 1949, an academic report on "Utilizing Hybrid Advantage to Improve Maize Yield" was published at the National Agricultural Work Conference, proposing that the breeding and promotion of intervariety hybrids as the main way to develop the utilization of maize heterosis in China was adopted by the five-year plan for the popularization of good seeds promulgated by the State Council and the "National Maize Improvement Plan" formulated by the Ministry of Agriculture. In 1952, in cooperation with Luoyang Agricultural Experimental Station, China's first comprehensive maize variety "Luoyang Mixed Selection No. 1" was developed. At the founding meeting of the Chinese Academy of Agricultural Sciences in 1957, the paper "From the promotion of a comprehensive variety - Luoyang Mixed Selection No. 1 to discuss the utilization and maintenance of maize heterosis" was read, which opened up a new way for the utilization of heterosis. Later, he published papers such as "The Utilization of Heterosis in New China's Maize Production and Its Prospects", "Three Suggestions for Current Maize Hybrid Breeding Work", and "The Impact of Remote Breeding on Maize Inbred Lines and the Possibility of Utilization in Production". In 1956, the remote breeding method he advocated has been adopted by various breeding units across the country. The Maize Research Institute of Henan Agricultural University, which he led, has successively developed and widely promoted excellent corn hybrids such as Yunong 704, Yudan No. 5, and Yushuang No. 5, which have won major scientific and technological achievement awards from the National and Henan Provincial Science Conferences respectively. Wu Shao Leng, an agricultural educator and crop breeder, is one of the founders of corn breeding in China. He has been engaged in the research on the utilization of maize heterosis for a long time, and first proposed the principle of rationally preparing maize double-crosses and selecting two-ring lines according to the similarities and differences of inbred lines or relatives; in the early 1950s, he advocated the breeding and utilization of inter-variety hybrids and comprehensive seeds in China, and adopted the method of off-site breeding to accelerate the generation process, which made contributions to the development of maize breeding in our country.
