RAPD MARKERS LINKED TO THE DISEASE RESISTANCE GENES IN CHINESE WILD VITIS
Random Amplified Polymorphic DNA (RAPD) and Bulked Segregant Analysis (BSA) were applied to detect molecular markers linked to disease resistance genes in Chinese wild Vitis and individuals from crosses between Chinese wild Vitis and cultivars of V.vinifera L. Two RAPD markers OPV03-1380 and OPJ16-750, linked to Uncinula necator resistance genes; three markers OPV02-600, OPJ13-300 and OPS03-1300, linked to Sphaceloma ampelinum resistance genes; OPP09-760, linked to Coniothyrium diplodiella resistance genes; OPC15-1300, linked to Glomerella cingulata resistance genes in Chinese wild Vitis were obtained.
The actual length of OPJ13-300, OPV02-600 and OPP09-760, were 305bp, 616bp and 769bp, respectively.
RAPD markers, which linked to Coniothyrium diplodiella and Glomerella cingulata resistance genes in Chinese wild Vitis, were converted into SCAR markers.
The acquired markers provide a solid basis for molecular-assisted selection (MAS) of disease resistance and for the breeding of varieties that are highly resistant to fungal diseases.
