Abstract: Jiyu 209, a new soybean variety, was bred by Soybean Research Institute of Jilin Academy of Agricultural Sciences. Jiyu 209 was derived from the hybrid of Gongjiao 0503-2（female） and Yan-08-2（male） by means of a pedigree selection method for several years. Participated in the regional test of the early maturity group of Northern Spring soybean in Jilin Province from 2018 to 2019, the average yield of Jiyu 209 was 2 542.8 kg·ha^-1, which was 6.8% higher than that of the control variety Hejiao 02-69. Participated in the production test in 2019, the average yield of Jiyu 209 was 2 524.5 kg·ha^-1, which was 6.9% higher than that of the control variety Hejiao 02-69. Jiyu 209 was approved by Jilin Provincial Crop Variety Certification Committee in 2020 with the authorized No.20200003.
