Soybean mosaic disease caused by soybean mosaic virus (SMV) occurs wherever soybean [Glycine max (L.) Merr.] is grown and is considered one of the most important soybean diseases in many areas of the world. Use of soybean cultivars with resistance to SMV is a very effective way of controlling the disease. China has rich soybean germplasm, but there is very limited information on genetics of SMV resistance in Chinese soybean germplasm and reaction of the resistance genes to SMV strains G1–G7. There also is no report on allelic relationships of resistance genes in Chinese soybeans with other named genes at the three identified loci Rsv1, Rsv3, and Rsv4. The objectives of this study were to examine reactions of Chinese soybean cultivar Zao18 to SMV strains G1–G3 and G5–G7, to reveal the inheritance of SMV resistance in Zao18 and to determine the allelic relationship of resistance genes in Zao18 with previously reported resistance genes. Zao18 was crossed with the SMV-susceptible cultivar Lee 68 to study the inheritance of resistance. Zao18 was also crossed with the resistant lines PI96983, L29, and V94-5152, which possess Rsv1, Rsv3, and Rsv4, respectively, to examine the allelic relationship between the genes in Zao18 and genes at these three loci. Our research results indicated that Zao18 possesses two independent dominant genes for SMV resistance, one of which is allelic to the Rsv3 locus; the other is allelic with Rsv1. The presence of both genes (Rsv1 and Rsv3) in Zao18 confers resistance to SMV strains G1–G7.
