| 摘 要： | 在陕西关中棉区，黄萎病对不同熟性棉花品种的严重危害不一，早熟品种在７月下旬，中熟品种为８月下旬，严重危害期对结铃数及铃重影响最大，对衣分影响较小，品种间影响差异不显著。棉花品种抗病性鉴定应以各严重危害的病情指数作区别指标。

| Abstract: | Serious harmfulness of Verticillium dahliae to different maturing cotton varieties take place in different period.Early-maturing variety is affected in late July,while middle-maturing cotton variety in late August.Effect of serious harmfulness on boll-bearing number and boll weight is greater than lint percentage,and there is not remarkable.Difference among varieties therefore,the author suggests that the disease level at serious effecting period can be used as a parameter for screening disease-resistant cultivars. |
