春大豆新品种宁京豆7号的选育及高产栽培技术

Breeding and High-yield Cultivation Technology of A New Spring Soybean Variety Ningjingdou 7

中国农业科学院作物科学研究所大豆基因资源课题组以长农17为母本、冀B04-6为父本进行有性杂交,2009年宁夏农林科学院农作物研究所对其后代定向筛选,在宁夏地区采用系谱法经过10年选育而成春大豆新品种宁京豆7号。品种主要特点是高产、高油、稳产和适应性好。2016—2017年宁夏区域试验平均产量4366.5 kg·hm^(-2),比对照承豆6号增产3.1%。2018年生产试验平均产量4167 kg·hm^(-2),较对照承豆6号增产6.3%。于2019年通过宁夏回族自治区农作物品种审定委员会审定,审定编号:宁审豆20190001,并定名为宁京豆7号。

The Soybean Gene Resource Research Group of Institute of Crop Science,Chinese Academy of Agricultural Sciences used Changnong 17 as female parent and Hebei B04-6 as male parent to carry out sexual hybridization,in 2009,the Crops Research Institute of Ningxia Academy of Agricultural and Forestry Sciences screened its offspring and a new spring soybean variety Ningjingdou 7 was developed by pedigree method in Ningxia after 10 years′breeding.The main features of Ningjingdou 7 are high yield,high oil,stable production,and good adaptability.From 2016 to 2017,the average regional test yield in Ningxia Province was 4366.5 kg·ha^(-1),and increased by 3.1%over the control of Chengdou 6.The average production rate of the 2018 production test was 4167 kg·ha^(-1),and increased by 6.3%over the control of Chengdou 6.In 2019 it was approved by the Ningxia Hui Autonomous Region crop variety validation committee,authorized number was 20190001,and named as Ningjingdou 7.
