高产抗病大豆新品种陇豆5号选育报告
Breeding Report of the High-yield and Disease-resistant New Soybean Variety Longdou 5
摘要
Abstract
In response to the complex natural conditions in Gansu Province,the scarcity of widely adaptable soybean varieties,and the slow increase in planting area,a new soybean variety Longdou 5,obtained from the progeny population of a cross with Jiyu 72 as female parent and Stout as male parent,was bred by the Institute of Crop,Gansu Academy of Agricultural Sciences over several years using the pedigree method.In the Gansu Province soybean variety(line)regional experiment conducted from 2021 to 2022,the average yield of Longdou 5 across 10 points over 2 years was 2 808.00 kg/ha,which was an increase of 3.20%compared to the control variety Longdou 2.In the production experiment conducted in Gansu Province in 2023,the average yield across 7 test points was 3 030.30 kg/ha,an increase of 4.30%compared to the control variety Longdou 2.Longdou 5 has an average growth period of 128 days and is classified as a medium-late maturing variety.It exhibits good field growth,good defoliation,resistance to lodging,resistance to mosaic virus disease and gray spot disease.The grains are plump and round with good commercial quality,containing 394.8 g/kg of crude protein(dry basis)and 202.1 g/kg of ether extract(dry basis).It has characteristics of high yield,stable yield,disease resistance,and wide adaptability.This variety is suitable for spring planting and can be cultivated in the rainfed agricultural areas(arid and semi-arid)and non-irrigated areas of Gansu Province,as well as in similar ecological regions using medium-late and late-maturing varieties.关键词
