Isolation and Identification of Colletotrichum and Screening of Anthracnose Resistant Varieties from Snap Bean
摘要
Abstract
In this study, we isolate and identify Colletotrichum from snap bean( Phaseolus vulgaris L. ), and screen anthracnose resistant resources from these varieties. The results show that the pathogenic bacterium separated by morphology and molecular identification is Colletotrichum. Leaves at seedling stage and pods at matured stage of 48 bean varieties were soaked in liquid of Colletotrichum. We found that in seedling stage 44 varieties were resistant, 4 varieties were susceptible, and among which 1 variety was highly susceptible. In matured period, 40 varieties were resistant, and 8 varieties were susceptible, and among which 3 varieties were highly susceptible. Correlation analysis was made by taking disease severity index of leaves and pods through SPSS software as varable force. The result shows resistances at seedling stage and maturing stage have very significant correlation. The related coefficients are Kendall: 0.315, Spearman: 0.411.关键词
