Pathogenicity Differentiation of Verticillium dahliae and Screening of Resistant Germplasm Resouces of Eggplant in Jilin Province
摘要
Abstract
In order to clarify the pathogenicity differentiation of Verticillium dahliae in eggplant of Jilin Province and screen for disease-resistant materials.Two materials with different resistance were selected as identification hosts.The pathogenicity differentiation of 45 strains of V.dahliae isolated from Jilin Province was studied using the root-dip method,and based on this,the resistance of 43 materials to V.dahliae was evaluated.The results showed significant differences in pathogenicity among different strains,which could be divided into three types.The Ⅰ type had strong pathogenicity,with an average disease index greater than 70,accounting for 31.11%of the tested strains.The Ⅱ type had moderate pathogenicity,with an average disease index between 30-70,accounting for 62.22%of the tested strains.The Ⅲ type had weak pathogenicity,with an average disease index lower than 30,accounting for 6.67%of the tested strains.Analysis of the correlation between pathogenicity,culture characteristics,growth rate,and pathogenic type revealed a weak correlation.Among the 43 materials,2 disease-resistant materials were screened,accounting for 4.65%of the screened materials,6 materials with medium resistance,accounting for 13.95%,14 materials were tolerant,accounting for 32.56%,while 21 materials were classified as moderately susceptible or susceptible,accounting for 48.84%.These results provide important resistant germplasm for breeding eggplants resistant to Verticillium wilt.关键词
