Breeding and Cultivation Technology of A New Soybean Cultivar Jiyu 3513 with High Protein Content and High Yield

A new soybean cultivar Jiyu 3513 with high protein and yield was developed by Jilin Academy of Agricultural Sciences by crossing of Gongjiao2002-311-1 and American variety MD0902 CD in 2010. The results of regional trials during 2019-2020 showed that its average yield was 3 303.7 kg·ha^-1,which was 4.4% higher than control cultivar Jiyu 47/Jiyu 303, and the highest yield was 3 743.3 kg·ha^-1.The results of production test in 2020 showed that its average yield was 3 242.5 kg·ha^-1, which was 5.2% higher than control cultivar Jiyu 303, and the highest yield was 3 626.7 kg·ha^-1. It has good properties of high and stable yield, and high seed protein content（44.62%）. Jiyu 3513 was approved by Jilin Provincial Crop Variety Certification Committee in 2021 Authorized No.20210024).
