| 摘 要： | 【目的】鉴定与筛选18份国外棉花种质黄萎病抗性、农艺性状，为丰富新疆棉花资源库提供黄萎病抗性资源。【方法】2018、2019年调查棉花农艺性状、黄萎病发病，检测吐絮期测产、取样考种、纤维品质。对主要农艺性状进行方差、各指标相关性、病情指数聚类分析。【结果】18份国外种质均为中早熟性类型；均为中等株高；果枝始节差异不显著，黄萎病高抗株系占5.55%,抗病占27.77%,耐病占44.44%,感病占22.22%;病情指数除了与有效果枝、马克隆值呈正相关，与其余指标呈负相关。病情指数聚类为抗、耐、感病三类，其中，4号为高抗材料。【结论】抗病材料6份分别为2、4、6、9、11、16号，耐病材料8份分别为1、3、5、7、8、12、14、15号，感病材料4份分别为10、13、17、18号；籽棉产量较高材料5份分别为3、4、9、11、15号，纤维品质较优材料3份分别为1、9、11号；筛选出2份抗病高产优质种质资源为9号和11号。

| Abstract: | 【Objective】 To enrich Xinjiang cotton resource pool and provide Verticillium wilt resistance resources from the introduced eighteen foreign cotton germplasm by identifying their Verticillium wilt resistance and agronomic characters. 【Methods】 The cotton agronomic traits, the incidence of Verticillium wilt, cotton yield, and the fiber quality were investigated and variance analysis of main agronomic traits, correlation analysis and cluster analysis of disease index were executed. 【Results】 Eighteen foreign germplasm belonged to medium and early maturity types with.There were one highly resistance, six resistance, eight tolerance and four susceptible germplasm to Verticillium wilt, accounting for 5.55%, 27.77%, 44.44% and 22.22%, respectively.The disease index was negatively correlated with plant height, first node of fruit branch, boll bearing per plant, boll weight per plant, lint percentage, yield of seed cotton, average length of upper part, strength of breaking ratio, uniformity index and elongation, but positively correlated with effective fruit branch and Micronaire value.The cluster analysis of disease index showed that they were divided into three clusters.Among the above types, No.4 was a high resistance material. 【Conclusion】 The Verticillium wilt resistance ability are screed and identified in the research.Verticillium wilt resistant germplasm are lines 2, 4, 6, 9, 11 and 16, and sensitive lines are 10, 13, 17 and 18.Furthermore, five germplasm with higher yields (line 3, 4, 9, 11 and 15) and three germplasm (1, 9 and 11) with better quality are also identified.Ultimately, two Verticillium wilt resistance germplasm (9 and 11) with high yield and good quality are screened out. |
