Abstract:: Andou 162 was released by the Soybean Research Institute, Heilongjiang Academy of Agricultural Sciences and Chunfeng Modern Agricultural Institute using the nematode-resistance No.12 and F1 of Kenfeng 18×Hartwig as female and male parents with sexual hybridization, shuttle breeding and pedigree method. In comparison to Nenfeng 18, it showed higher yield in Heilongjiang regional trials in 2016 and 2017 (2 587.1 kg?ha-1 on average, with an increase of 10.9%) and production trial in 2018 (2 491.0 kg?ha-1 with an increase of 13.6%). Andou 162 was approved by Heilongjiang Crop Variety Approval Committee in 2019. The seeds are rich in protein and fat contents (42.07% and 20.30%, respectively) and have resistance to race 3 of soybean cyst nematode. Moreover, the seeds have improvements in appearance (due to the broken linkage between resistance gene and brown hilum), with yellow coat and hilum. Andou 162 is a new high-quality, high-yield and disease-resistant soybean variety.
