Breeding Research of A New Summer Soybean Variety Shengdou 16 Approved by National Crop Variety Approval Committee in Two Areas
In order to improve the yield and the quality,and cultivate new soybean varieties with high and stable yield,wide adaptability,high protein,density tolerance and are convenient for mechanical harvesting,Shandong Shengfeng Seed Industry Science and Technology Co.,Ltd.used Luhuang 1 as the female parent and Fendou 56 as the male parent to prepare a hybrid combination in 2009.The new summer soybean variety Shengdou 16 was selected by the mixed method after years of identification.From 2018 to 2020,it participated in the green channel regional test and production test of the southern group of Huang-Huai-Hai summer soybean.The main indexes such as yield,quality,disease identification and variety specificity all met the national variety approval standards.In 2021,it was successfully approved by the National Crop Variety Approval Committee(Announcement No.500 of the Ministry of Agriculture and Rural Affairs of the People's Republic of China,Approval No.:National Approval Bean 20216001).From 2020 to 2022,it participated in the regional test and production test of green channel varieties in the early and middle maturity group of summer soybean in the Yangtze River Basin.The variety approval indicators were better than the control.In november 2023,it was approved by the third variety approval meeting of the fifth National Crop Variety Approval Committee(Announcement No.726 of the Ministry of Agriculture and Rural Affairs of the People's Republic of China,Approval No.:National Approval Bean 20232011).In the process of variety breeding,attention was paid to the improvement of yield and quality traits.At the same time,the adaptability,yield stability and supporting cultivation techniques of Shengdou 16 in different regions were discussed.The variety showed the characteristics of wide adaptability,high yield,high protein,lodging resistance,easy mechanical harvest and good seed commodity.It has a good prospect of popularization and application in summer soybean planting areas in Shandong,He'nan,Anhui,Jiangsu,Chongqing,Hubei,Jiangxi and Hu'nan provinces.
