| 摘 要： | 【目的】 研究新疆当前棉花主栽品种对红腐病和立枯病的抗性,为病害的高效防控提供依据。【方法】选用拟轮枝镰孢霉和立枯丝核菌新疆菌株,通过人工接菌条件下的室内盆栽鉴定和田间小区试验,分析新疆20个棉花主栽品种对红腐病和立枯病的单一抗性水平和兼抗水平。【结果】大多数棉花品种对2种病害存在显著或极显著的抗性差异;供试品种中没有表现为免疫或高抗的品种,多数品种对2种病害表现为感病或高感,仅有少数品种对红腐病或立枯病表现为抗病或中抗;对红腐病表现为抗病的有中棉72号和新陆早53号,表现中抗的有中棉50号、新陆早57号和新陆早61号等5个品种;对立枯病表现为中抗的有新陆早53号、中棉72号和中棉50号等6个品种;对2种病害的兼抗性表现为中抗的有新陆早53号、中棉72号和中棉50号等6个品种。【结论】当前新疆棉花主栽品种中,对红腐病和立枯病均存在显著的抗性差异,缺乏对红腐病和立枯病高度抗病品种;对2种病害的抗性存在一定程度的关联,对立枯病表现为中抗的品种多数兼具对红腐病的抗性。

| Abstract: | 【Objective】 In order to investigate the resistance of the current main cotton cultivars in Xinjiang to fusarium red rot and rhizoctonia damping off, and to provide the basis for the effective control of diseases.【Method】Xinjiang strains of Fusarium verticilliodes and Rhizoctonia solani were selected and the single resistance level and concurrent resistance level of 20 main cotton cultivars to fusarium red rot and rhizoctonia damping off in Xinjiang were analyzed by indoor pot culture and field experiment under artificial inoculation.【Result】The results showed that:Most varieties had significant or very significant resistance differences to 2 diseases. Among the tested cultivars, there was no immune or high-resistance variety, and most of the cultivars showed a sensitivity or high sensitivity to the disease. Only a few of them showed resistance to or middle resistance to fusarium red rot or rhizoctonia damping off. In the present study, Zhongmian 72 and Xinluzao 53 showed resistance to fusarium red rot, and there were 5 varieties such as Zhongmian 50, Xinluzao 57 and Xinluzao 61, etc. that were moderately resistant. Six varieties with moderate resistance to rhizoctonia damping off were Xinluzao 53, Zhongmian72 and Zhongmian 50, etc. and 6 varieties with moderate resistance to two diseases were Xinluzao 53, Zhongmian72 and Zhongmian 50, etc. were found to be moderately resistant.【Conclusion】There are significant differences in resistance to fusarium red rot and rhizoctonia damping off in the main cotton cultivars in Xinjiang at present, but lack of varieties with high resistance to these diseases. There was a certain degree of association between the resistance of the 2 diseases, and the resistance of the damping off showed that most of the varieties were resistant to fusarium red rot. |
