Abstract: Qinong 10 is a high-yield soybean variety developed and popularized by Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences. The results showed that the average protein content was 39.88% and fat content was 19.69%, the average yield of regional test was 2 800.5 kg·ha^-1, which was 10.6% higher than that of control variety Beidou 40, the average yield of production test was 2 694.2 kg·ha^-1, which was 10.5% higher than that of control variety Beidou 40. From 2019 to 2020, the demonstration planting of Qinong 10 was carried out in Xinlong village, Gucheng Town, Keshan County. The field growth was uniform and orderly, the stem was strong and lodging resistant, the internodes were short, the pods were dense, the appearance of the seeds was golden yellow, full and round, and the yield was outstanding. The demonstration field created a typical high yield of 3 093.8 and 3 762.0 kg·ha^-1, respectively.
