从品种资源角度研究了棉花黄萎病菌侵害对陆地棉品种主要性状的影响。在黄萎病菌侵害下 ,单株结铃数、果枝数大幅度减少 ,单株结铃数分布明显发生变化。黄萎病菌侵害改变了一些性状的相关关系。由非侵害状态下单株结铃数与衣分的正相关、与籽指的负相关改变为侵害状态下与衣分的相关不显著 ,与籽指呈显著正相关 ;在黄萎病菌侵害与非侵害状态下果枝数、单株结铃数及衣分相关不显著 ,而单铃重、籽指及纤维长度呈极显著正相关
From the perspective of variety resources, the effects of Verticillium dahliae invasion on the main characters of upland cotton varieties were studied. Under the attack of Verticillium dahliae, the number of bolls per plant and the number of fruit branches significantly decreased, and the number distribution of bolls per plant obviously changed. Verticillium wilt invasion has changed the relationship of some traits. There was a positive correlation between the number of bolls per plant and the litter size in the non-invasive state, the correlation between the number of bolls per plant and the litter size in the non-invasive state, There was no significant correlation between number of fruit branches, number of bolls per plant and lint percentage under non-invasive condition, but significant correlation was found between single boll weight, seed index and fiber length
