摘　　要：为促进高产、宜机收大豆新品种湘春2701的推广,本文对湘春2701的选育过程、特征特性、产量表现及栽培技术要点、品种选育思考及应用前景进行了系统阐述。湘春2701是湖南省作物研究所2008年春以湘春豆24为母本,油春01-45为父本有性杂交,经系谱法和摘荚混合法选育而成的高产广适春大豆新品种。2017—2018年参加湖南省两年春大豆品种区域试验,平均产量2760.0 kg·hm^(-2),比对照湘春豆24增产7.2%;2018年生产试验,平均产量2914.5 kg·hm^(-2),比对照湘春豆24增产9.6%;2018—2019年参加长江流域春大豆组品种区域试验,平均产量2959.5 kg·hm^(-2),比对照天隆一号增产3.7%;2019年生产试验,平均产量2752.5 kg·hm^(-2),比对照天隆一号增产3.6%。该品种在各级试验中均表现综合性状优良,于2019年通过湖南省农作物品种审定委员会审定,2021年通过国家农作物品种审定委员会审定,审定编号分别为湘审豆20190001和国审豆20210062。湘春2701籽粒椭圆形,大小均匀,外观品质优良,同时落叶性好,底荚高度较高,适宜机械化播种收获,该品种在适宜在长江中下游地区作春播种植。In order to promote the promotion of the new high-yield and machine harvesting soybean variety Xiangchun 2701,this article systematically elaborates on the breeding process,characteristic,yield performance,cultivation technology points,variety selection thinking,and application prospects of Xiangchun 2701.Xiangchun 2701 is a new high-yield and suitable spring soybean variety developed by the Hunan Crop Research Institute in the spring of 2008,using Xiangchun 24 as the female parent and Youchun 01-45 as the male parent through sexual hybridization,and breeding through pedigree and pod picking mixed methods.Participated in a two-year regional trial of spring soybean varieties in Hunan Province from 2017 to 2018,with an average yield of 2760.0 kg·ha^(-1),an increase of 7.2%compared to the control Xiangchun 24.In the 2018 production experiment,the average yield was 2914.5 kg·ha^(-1),which increased by 9.6%compared to the control Xiangchun 24.Participated in the regional trial of spring soybean varieties in the Yangtze River Basin from 2018 to 2019,with an average yield of 2959.5 kg·ha^(-1),an increase of 3.7%compared to the control Tianlong 1.In the 2019 production experiment,the average yield was 2752.5 kg·ha^(-1),which increased by 3.6%compared to the control Tianlong 1.This variety has shown excellent comprehensive characteristics in all levels of experiments.It was approved by the Hunan Provincial Crop Variety Approval Committee in 2019 and the National Crop Variety Approval Committee in 2021.The approval numbers are Xiangshen 20190001 and Guoshendou 20210062,respectively.Xiangchun 2701 has oval shaped seeds with uniform size and excellent appearance quality.At the same time,it has good deciduous properties and a high height of the bottom pod,making it suitable for mechanized sowing and harvesting.This variety is suitable for spring sowing and planting in the middle and lower reaches of the Yangtze River.
