At the beginning of the new year, the Anhui Academy of Agricultural Sciences announced that the world’s first hybrid summer soybean, named “Zhuyoudou 1â€, was successfully bred in this hospital and has been approved by the Anhui Crop Variety Approval Committee. In 1989, Zhang Lei, a researcher at the Institute of Crop Research of the Anhui Academy of Agricultural Sciences, discovered soybean male sterile lines in a variety of interspecific cross combinations. After cross-crossing, test-crossing, continuous backcrossing, and repeated verification and breeding, in 1997, the world’s first cultivated summer soybean cytoplasmic nuclear male sterile line and homotypic maintainer line were found. At the same time, the restorer line was found and the “three lines†were realized. "Supporting. The bred M-nuclear interaction male sterile line became China's first male sterile line that was applied for and authorized by the Ministry of Agriculture. "Zhuyoudou 1" showed the advantages of disease resistance, high lodging resistance, high yield and stable yield in the soybean regional test and production test in Anhui Province. The average yield per mu in the two-year regional test was 191.16 kg, which was 19.14% more than the control and the protein content was increased. 43.56%%, fat content 18.96%%, good commercial quality, demonstration of 278.6 kg per mu. The results of the 37 cross combinations showed that the quality of the hybrid summer soybeans increased significantly while the quality did not decrease and slightly increased. Experts believe that this hybrid combination is suitable for the cultivation of medium-maturing varieties in Huanghuaihai and Jianghuai regions. In the Huang-Huai-Hai area of ​​China, the annual summer soybean planting area is 40 million mu, and in Anhui province alone there is about 8 million mu. The promotion and planting of hybrid summer soybean will produce huge economic benefits, and it will also have important significance for safeguarding China's food security. Hybrid soybeans are another major breakthrough in the utilization of heterosis in crops following hybrid rice, hybrid corn, hybrid cotton and hybrid wheat. The hybrid summer soybean was the first spring soybean planted in the Jilin Academy of Agricultural Sciences and another officially approved soybean hybrid that could be industrialized.
