Breeding and Cultivation Technology of A High Protein Soybean Variety Kehe Green Soybean No.1

为促进高蛋白大豆新品种的推广应用,本文简要介绍了科合绿大豆1号的选育过程、特征特性、产量表现、适应种植区域及栽培技术要点。科合绿大豆1号是属于高蛋白大豆新品种,由黑龙江省农业科学院以引进日本大豆材料HZDD3605为母本、捷克大豆材料HZDD767为父本经过有性杂交选育而成。该品种亚有限结荚习性,紫花,圆叶,棕色茸毛,株高70 cm左右,百粒重17.5 g左右。2018-2019年参加黑龙江省区域试验,平均产量2415.4 kg·hm^(-2),较对照品种黑河45平均增产10.2%。经农业农村部谷物品质监督检验测试中心(哈尔滨)检测,科合绿大豆1号粗蛋白质(干基)含量高达49.2%。该品种于2021年通过黑龙江省农作物品种审定委员会审定(审定编号:黑审豆20210050),生育日数108 d,适应于黑龙江省第五积温带区域种植。

In order to promote the popularization and application of new high protein soybean varieties,this paper briefly introduced the breeding process,characteristics,yield performance,suitable planting area and cultivation technology of Kehe green soybean No.1.Kehe green soybean No.1 was a new high protein soybean variety.It was selected by Heilongjiang Academy of Agricultural Sciences through sexual hybridization with the imported Japanese soybean material HZDD3605 as the female parent and the Czech soybean material HZDD767 as the male parent.The variety had sub finite podding habits,purple flowers,round leaves,brown fur,plant height of about 70 cm and 100-seed weight of about 17.5 g.From 2018 to 2019,Kehe green soybean No.1 was participating in the regional test in Heilongjiang Province,with an average yield of 2415.4 kg·hm^(-2),an average increase of 10.2%compared with the control variety Heihe 45.According to the Grain Quality Supervision and Testing Center of the Ministry of Agriculture,the content of crude protein(dry basis)of Kehe green soybean No.1 was 49.2%.The variety was approved by Heilongjiang Crop Variety Approval Committee in 2021,with 108 days of growth period,and was suitable for planting in the fifth temperate zone of Heilongjiang Province.
