Abstract: In order to promote the application and popularization of high gelatin resistant soybean variety Qinong No.12,the breeding process,yield performance,characteristics and related cultivation techniology were introduced in detail.Qinong No.12 was bred by crossing Hefeng 50 as female parent and MN0902 as male parent in Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences.Its 11 S∶7 Sglobulin ratio is 2.4 to 2.6,gel is good,and is suitable for processing soybean protein isolate.The average protein content is 39.71%,the average fat content is 20.76%,and the resistance to soybean cyst nematode is high.The average yield of the regional trial is 2 783.2 kg·hm^-2,which is 14.8% higher than that of the control variety Nenfeng 18,and the average yield of the production test is 2 832.6 kg·hm^-2.Compared with the control variety Nenfeng 18,the yield increased by 15.0%.Due to its outstanding quality and yield,it was approved and promoted by Heilongjiang Crop Variety Approval Committee in 2020（Heishendou20200005）.
