Abstract: Black beau varietids Huibuzhi, Chibuliu and Xiaoheidon, Which are resistant to physiological races 1,2,3,4 of soybean cyst nematode (SCN),were crossed with some spreading varieties.Fourteen new lines with yellow seed colour and resistance to race 4 of SCN were selected by several years selective breeding.Through several years identification, these new lines are stablly resistant and average root nematode are less than 10, among which average root nematodes of 10 lines are lizs than 3.These 10 lines belong to highly resistant appearins erecting and unlodging,their 100-seed weight increase 50% compared to their resistant parents,and yields per mu are 125-150kg,10-15%higher than their resistant parents, and close to and surpass high parents yields.These new lines can be used directly in soybean production,especially in Huang, Huai and Hat aress highly affected by race 4 of SCN,and can also be used for middle materiales of soybean breeding.
