摘要： Soybean cyst nematode (SCN) is a destructive threat to soybean production. It is economically important to develop a new SCN-resistant soybean cultivar with high yield and other good agronomic traits. In this study, a yellow-seed-coated and yellow-hilum-pigmented cultivar Heinong 531 belonging to maturity group I was developed by a pedigree breeding method through a test-cross between a female parental SCN-resistant soybean cultivar Pengdou 158 and a male parental line F-1 (high-yield but SCN-susceptible Hefeng 55 x SCN-resistant Kangxian 12). Heinong 531 was evaluated for SCN resistance in both SCN-infested field and autoclaved soil inoculated with hatched second-stage juveniles of SCN HG Type 0. The results indicated that SCN development at all stages in Heinong 531 was suppressed and the female index was only 1.6 to 5.6%. Heinong 531 as well as Pengdou 158 and Kangxian 12 were identified as carrying the Peking-type resistance with both rhg1-a GmSNAP18 and Rhg4 GmSHMT08 genes. In the 2-year regional trials, the average yield of Heinong 531 reached 2805.0 kg/ha, and the 1-year production trial demonstrated an average yield of 2,751.5 kg/ha with yield increase of >12.0% when compared with the local cultivars. The average seed-fat (oil) contents of Heinong 531 reached up to 22.3%. The Peking-type SCN-resistant Heilong 531 with enhanced yield and high seed-oil contents was released in China in June 2021 with the certified number of 'Heishendou 20210004'. These agronomic traits make Heinong 531 a good prospect in a wide attempt to control SCN in the main soybean-producing areas of Northeast China.
