通过对江西省2010～2014年度共113份棉花区试品种抗枯萎病性鉴定结果的分析，结果表明：高抗、抗病、耐病、感病4个类型材料数年度间占比变化波动较大，尤以抗病和耐病类型变化幅度大，两者占比合计达到70.8％；各类型年度间平均相对病指变化幅度较小，感病品种的平均相对病指呈逐年减小趋势，品种的抗枯萎病性总体水平有提高趋势。

Through the analysis of resistance to wilt disease identification results of 113 cotton varieties in Jiangxi prov-ince from 2010 to 2014,the results showed that the proportion of 4 types of high resistance,resistance,tolerance and suscep-tible disease changed large fluctuations ,but but the change was existed between resistance and tolerance varieties,the total percentage of these two types was 70.8%.The changed amplitude of relative disease index in the 4 types was small,and the average relative disease index of susceptible veriety had the trend of decreasing year by year,the resistance to Frustum wilt of cotton varieties was better and better relatively.
