摘要： Soybean mosaic virus is a severe constraint of soybean production in China. A total of country-wide 22 SMV strains (SC1-SC22) were identified. Of these, SC3 is a major strain widely distributed in Huanghuai and Yangtze River Valley region of China. Soybean cultivar 'Qihuang-1' contains R-SC3Q locus conditioning the resistance to SC3 and is an important parental line extensively used to breed the soybean cultivars in China. The objective of this study was to elucidate the genetic pattern of SC3 resistance genes in cultivars developed from 'Qihuang-1' or its derivative lines. Hence, we have evaluated the SC3 resistance in 91 cultivars developed from 'Qihuang-1' or its derivative lines. The results showed that a total of 43 cultivars exhibited resistance to the SC3 strain. Among them, 37 cultivars were derived from 'Qihuang-1'. Then, we have detected the R-SC3Q loci in these cultivars using four SSR markers (Satt334, Sct_033, BARCSOYSSR_13_1114 and BARCSOYSSR_13_1136). It revealed that, among the 37 resistant cultivars derived from 'Qihuang-1', there are 20 cultivars containing R-SC3Q loci. Moreover, the allelic relationship of resistance genes was analysed using the crosses from resistance x resistance between 'Qihuang-1' and its resistant derived cultivars. The results showed that the resistance genes of 'Qihuang-1' and its 20 cultivars were allelic. But it is not allelic with those of the other 17 cultivars, different from 'Qihuang-1', and also, R-SC3Q does not condition the resistance. These results will be beneficial to exploring the transmission of resistance genes of 'Qihuang-1' and will be useful to the disease resistance breeding of soybean.
