Rpv34: A novel plasmopara viticola resistance locus discovered in 'Moldova' grapes

A research team identified a P. viticola-resistant locus, Rpv34, in table grapes through analysis of a high-density genetic map with 826 SNPs derived from F1 progenies of "Moldova" (resistant) and "Shine Muscat" (susceptible parent). This discovery, including the identification of 21 Resistance Gene Analogs and a highly associated SNP marker, enhances understanding of resistance mechanisms and supports the breeding of resistant grape varieties, which may improve grape quality and production.
