摘要: In this report we identified QTLs conferring resistance to Sugarcane Mosaic Virus (SCMV) and their use in marker-assisted selection (MAS) was described. The genetic linkage map covering 1543 cM on ten chromosomes with an average interval of 17.3 cM was constructed with 89 SSR marker loci based on a maize population consisting of 184 F-2 individuals from the cross Huangzao4 (resistant)xYe107 (susceptible). The population of 184 F-2:3 families was phenotyped for resistance to SCMV under artificial inoculation at four developmental stages (seedling, elongation, anthesis, and grain-filling). With the method of composite interval mapping, three QTLs conferring resistance to SCMV were detected on chromosomes 3, 5, and 10 at seedling stage; four QTLs on chromosomes 3, 5, 6, 10 at elongation and anthesis stages; and five on chromosomes 3 and 10 showed significant additive gene effects, while the other three QTLs on chromosomes 1, 5 and 6 displayed dominant, over-dominant and partial dominant effects, respectively. Two major QTLs on chromosomes 3 R-scm1 and 10 R-scm3, explaining 7.2% to 26.9% and 15.3% to 15.8% of the phenotypic variance, were consistently detected at four stages. Based on this study, it was recommended that the MAS approach for SCMV resistance, combined with conventional selection method, could employ the QTLs on chromosomes 3, 5 and 10.
