摘要
对陕西省2003-2007年79个棉花区试品种(系)抗病性鉴定分析结果表明,多数品种呈高抗枯萎病,近年枯萎病总体抗性水平有下降趋势。高抗黄萎病棉花品种很少,黄萎病总体抗性水平呈增强趋势。筛选出17个对枯、黄萎病表现较好的兼抗性品种(系)。
The resistance of cotton to Fusarium wilt and Vertillium wilt were evaluated with 79 varieties (lines) from Shaanxi provincial regional trials during the period of 2003- 2007. The results showed that most of the varieties (lines) had high or middle resistance to Fusarium wilt, but the ratio of the varieties (lines) with high resistance to Vertillium wilt was low. In total, the resistance of cotton to Fusarium wilt had been lowered while the resistance to Vertillium wilt increased. In the these varieties (lines), 17 ones had better resistances to both of the diseases than that of others.
