Identification of resistance of 132 grape germplasm resources to leaf gray mold
In order to determine the resistance of different grape cultivars to leaf gray mold,132 grape germ-plasm resources were evaluated by artificial inoculation.The results showed that the resistance of different grape varieties varied greatly.Two grape germplasm resources were scored as high resistance(HR,accounting for 1.51％),14 accessions were resistant(R,accounting for 10.61％),89 accessions were moderately resist-ant(MR,accounting for 67.42％),22 accessions were susceptible(S,accounting for 16.67％),and 5 acces-sions were highly susceptible(HS,accounting for 3.79％).No accession showing immune was identified.Muscadinia rotundifolia Michx.cultivars were the most resistant to gray mold,the Vitis labrusca L.and V.vinifera L.X V.labrusca L.cultivars were the second most resistant to gray mold,the V.vinifera L.cul-tivars were susceptible to gray mold.In addition,local germplasm resources Yunxiputao was resistant to gray mold.These results provided excellent grape germplasm resources for gray mold resistance breeding and the relevant research.
