夏大豆新品种山宁23的选育及栽培技术

Breeding and Cultivation Techniques of A New Summer Soybean Variety Shanning 23

山宁23是以鲁豆12为母本,滑豆尖叶为父本,经有性杂交系谱法选择育成,2021年由国家农作物品种审定委员会审定推广,审定编号为国审豆20210056。该品种2018—2020年参加黄淮夏大豆南片品种试验,2018—2020年3年区域试验平均产量2793 kg·hm^(-2),比对照品种中黄13增产2.1%,2020年生产试验,平均产量2697.0 kg·hm^(-2),比对照品种中黄13增产3.9%;粗蛋白质含量44.55%,粗脂肪含量21.19%;生育日数平均为95.5 d,比对照品种早熟1.0 d;籽粒圆形,大小均匀,顶土能力强,出苗速度快,适宜机械精量播种;株型紧凑,抗倒耐密,不炸荚,落叶性好,适宜机械化收获和麦茬直播夏大豆绿色增产增效栽培技术模式。山宁23的创制与育种体会,对大豆新品种的选育与生产具有借鉴与指导意义。

Shanning 23 was bred by sexual hybridization pedigree method with Ludou 12 as female parent and Huadoujianye as male parent.It was approved and promoted by the National Crop Variety Approval Committee in 2021,with the approval number of Guoshendou 20210056.It participated in the variety test of Huanghuai summer soybean in the south area from 2018 to 2020.In the regional test in 2018—2020,the average yield of this variety was 2793 kg·ha^(-1),which was 2.1%higher than that of the control variety Zhonghuang 13.In the production test of 2020,the average yield was 2697.0 kg·ha^(-1),which was 3.9%higher than that of the control variety Zhonghuang 13.The crude protein content was 44.55%,and the crude fat content was 21.19%.The average growth days were 95.5 d,1.0 d earlier than that of the control variety.The seed is round,uniform in size,strong groundbreaking ability,fast in seedling emergence,and suitable for mechanical precision sowing.The plant type is compact,lodging-resistant and dense,not shattering,and has good defoliation.It is suitable for mechanized harvesting and wheat stubble direct seeding summer soybean green yield-increasing and efficiency-increasing cultivation technology model.The creation and breeding experience of Shanning 23 has reference and guiding significance for the breeding and production of new soybean varieties.
