兴豆7号是兴安盟农牧科学研究所于2009年以春优439为母本,合99-718(合丰50)为父本进行有性杂交,经系谱法选育而成的高油大豆新品种。2016-2017年参加内蒙古自治区大豆中早熟组品种区域试验,2年区域试验平均产量为2613.8 kg/hm^(2),较对照品种丰豆2号增产9.8%。2018年参加内蒙古自治区大豆中早熟组品种生产试验,平均产量为3530.6 kg/hm^(2),较对照品种丰豆2号增产6.8%。该品种粗脂肪含量为24.24%,粗蛋白含量为36.74%,适宜≥10℃活动积温2500℃以上地区春播种植。2019年通过内蒙古自治区农作物品种审定委员会审定,审定编号为蒙审豆2019008。

Xingdou 7 was a new high-oil soybean cultivar,which was bred by Hinggan League Agricultural and Animal Husbandry Sciences Research Institute through sexual hybridization and pedigree selection with Chunyou 439 as the female parent and He 99-718(Hefeng 50)as the male parent in 2009.From 2016 to 2017,it paticipated in regional trial of Inner Mongolia Autonomous Region soybean mid-early mature group,the average yield in two years was 2613.8 kg/ha,which was 9.8% higher than that of control cultivar Fengdou 2.In 2018,it paticipated in production trial of Inner Mongolia Autonomous Region soybean mid-early mature group,the average yield was 3530.6 kg/ha,which was 6.8% higher than that of control cultivar Fengdou 2.The crude fat content was 24.24%and crude protein content was 36.74%,which was suitable for planting in spring planting area with an active accumulated temperature of≥10℃ and above 2500℃.In 2019,it passed the approval of the Inner Mongolia Autonomous Region Crop Variety Approval Committee,and the approval number was Mengshendou 2019008.
