| description | Downy mildew (DM), caused by Plasmopara viticola, is one of the most serious diseases that affects grape production worldwide. Utilizing host resistance, commonly known as 'R' genes, is considered the most effective way to cure the disease. The identification of the R gene in well-known table grape cultivars is conducive to breeding varieties with better quality. In this study, a population of F1 with 246 progenies was obtained from the cross of two widely grown table grapes 'Moldova' and 'Shine Muscat', in which 'Moldova' appeared resistant to P. viticola resistance. According to the sequencing data from GBTS, a high-density genetic map containing 826 SNPs, which spanned 1,515.99 cM, was constructed. Through the analysis of MapQTL and GWAS, a resistant locus for P. viticola was mapped, located at 27.534−30.729 Mbp in chr18, and was named Rpv34. A total of 21 Resistance Gene Analogues (RGA) distributed in three clusters were identified in this locus. A SNP marker chr18_29062596 was proved to be highly associated with resistance to P. viticola. This work will improve the mechanism of resistance understanding of P. viticola in grapevine and facilitate the use of resistant germplasm in breeding. |
