高产早熟大豆新品种陇豆7号选育报告
Breeding Report on the High-yield and Early-maturing New Soybean Variety Longdou 7
摘要
Abstract
To revitalize the soybean industry in Gansu Province and develop a new soybean variety suitable for soybean-maize intercropping and multiple cropping systems,the Crop Research Institute of the Gansu Academy of Agricultural Sciences,in collaboration with the State Key Laboratory of Agrobiotechnology(the Chinese University of Hong Kong),bred a new high-yield,early-maturing,and machine-harvestable soybean variety,Longdou 7.The cross was made using Wenfeng 7 as the female parent and Union(PI548622)as the male parent,followed by pedigree selection.In regional experiments for new soybean varieties(lines)conducted in Gansu Province during 2022 to 2023,the average equivalent yield of Longdou 7 was 3 098.0 kg/ha,8.3%higher than the control variety Zhonghuang 30.In 2024 production experiment for new soybean varieties in Gansu,the average equivalent yield reached 3 538.7 kg/ha,8.6%higher than Zhonghuang 30.The variety has an average growth period of 120 days,with a single-plant seed weight of 23.5 g and a 100-seed weight of 20.5 g.The grain contains 403.7 g/kg crude protein and 205.8 g/kg ether extract.Longdou 7 was approved by the Gansu Provincial Crop Variety Approval Committee in 2025(Approval No.Ganshendou 20251002).It is suitable for spring sowing in the mid-late and late-maturing variety region of Gansu Province as well as for soybean-maize strip intercropping and summer multiple cropping in the east and southern parts of Gansu.关键词
