高油高产大豆新品种‘合农72’的选育

New Soybean Variety ’Henong 72’ with High Oil Content and High Yield: Breeding

为了选育既高油又高产的大豆新品种,提升中国油用大豆生产优势和商品大豆市场竞争力,通过亲本系谱与血缘关系、基因与性状遗传及亲本使用效果分析,优选亲本、配制组合与创建选择群体,优化育种技术与检测分析方法,育成了高油高产大豆新品种‘合农72’,2018年由黑龙江省农作物品种审定委员会审定推广。该品种油分含量达到23.42%;区域试验平均产量3099.1 kg/hm^2,较对照品种‘合丰51’增产9.2%,生产试验平均产量3125.9 kg/hm^2,较对照品种‘合丰51’增产13.0%;生育日数115天左右,需≥10℃活动积温2300℃左右,适宜北方春大豆中早熟区种植;接种鉴定:中抗灰斑病。

To breed new soybean varieties with high oil content and high yield, enhance the production advantage and market competitiveness of oil extraction soybean, a new high oil content and high yield soybean variety‘Henong72’was bred by analyzing parental genealogy and kinship, genes and character inheritance and the parental using effects, to select excellent parents, arrange hybrid combination, establish selection population and to optimize design of breeding technology and detection. This soybean variety was validated and promoted by Heilongjiang Provincial Crop Committee in 2018. The oil content is 23.42%. The average yield of regional trial is 3099.1 kg/hm^2, 13.0% higher than that of the control variety‘Henong51’. The growth period is115 days approximately and the active accumulated temperature ≥10℃ is 2300℃. The variety is suitable for planting in the mid-early maturing producing area of northern spring soybean, and has medium disease resistance to gray spot.
