MARKER ASSISTED SELECTION FOR SEEDLESSNESS IN A MULTIRESISTANT TABLE GRAPE HYBRID FAMILY
Resistant table grape cultivars, without any compromise in quality and resistance, would be greatly advantageous for consumers. In this study, the cross VRH 3082-1-42 × Kishmish moldvaskii has been used to investigate the usefulness of the SSC8 marker for MAS. The SCC8 marker results were consistent with the progeny phenotypes. Although the seeded parent showed an unusual genotype, the genotyping of the population could be carried out. We traced back the haplotypes of the resistant donor parent. Based on our findings, the dominant, seedlessness-linked SCC8+ allele of the seeded VRH 3082-1-42 should be considered as a recombinant; the presence of a null allele could be explained by larger DNA rearrangements instead of mutations in the priming sites.
