| Abstract: | With F1 individuals of the cross combination 88-110 of 83-4-96 ( V. quinquangularis Rehd. )× Muscat Rose ( V. vinifera L. ), the RAPD marker OPC15-1300 linked to ripe rot ( Gloeosporium fruetigenum Berk. ) resistance genes in Chinese wild Vitis was gained using bulked segregation analysis(BSA). And it was found that OPC15-1300 could be hereditary from the resistant parent (83-4-96) after the marker was tested in 50 F1 plants of the cross combination 88-110, 32 accessions of 8 Chinese wild Vitis species and 14cultivars of V. vinifera L. Also, it has provided a solid basis for molecular marker-assisted selection (MAS)and for possibly cloning disease resistance genes in the future. |
