| 摘 要： | 通过对陕西省2009-2015年棉花区域试验及生产试验160个陆地棉棉花品种（系）的抗枯黄萎病的鉴定结果分析，未发现对枯萎病和黄萎病均免疫的品种。对枯萎病呈高抗的品种有71个，占测试品种的38.1%；未发现对黄萎病高抗的品种，达到抗性水平的品种有77个，占测试品种的48.1%。从7 a测试结果来看，对枯萎病抗性水平总体呈下降趋势，对黄萎病抗性水平总体呈增强趋势，但未见对黄萎病抗性水平达到高抗及以上的品种。共筛选出7个品种（系）对枯黄萎病表现突出的兼抗性。

| Abstract: | After resistance screening and evaluation of 160 cotton varieties (lines) in Shaanxi province from 2009-2015,no variety immune to both Fusarium wilt and Verticillium wilt was identified. About 38.1%,71 varieties,showed high resistance to Fusarium wilt. About 48.1% (77 varieties) were resistant to Verticillium wilt,but no high resistant variety (line) was found. From the screening and evaluation results between 2009 and 2015,the level of resistance to Fusarium wilt decreased along with time,while the resistance to Verticillium wilt increased. In this study,we screened out 7 varieties (lines) that are resistant to both Fusarium wilt and Verticillium wilt. |
