Abstract:Jidou4, which was developed through sexual hybridization by Handan agriculture academy of sciences, was an elite soybean variety with high yield, high quality, resistant and wide adaptability. It won the third prize of national science and technology progress in 1990. 16 varieties were developed from Jidou4 and its derivative materials through hybridization or mutation in Hebei, Shanxi and Shan’xi, among which 7 varieties were approved by National Crops Variety Approval Committee, 5 varieties were high oil with the fat content among 21.79% -23.97%. These varieties are fit to plant in Huanghuai and Northeast where were major producing areas in China and play an important role in soybean production. Jidou4 was widely used in breeding that demonstrated it’s not only an excellent variety, but also a rare elite germplasm. Screening and cultivating excellent germplasm is a basic work for soybean research.
