摘要：

为了评价棉花资源的群体结构，利用65个SSR标记对81份栽培棉花材料进行扫描，分析了该资源的群体结构，并对8个棉纤维品质性状数据/基因型数据进行关联分析。结果表明，该群体分为两个亚群。关联分析发现，以两年表型平均值检测到18个位点与棉纤维品质性状相关，其中5个位点与两个以上（含两个）性状相关。在这18个位点中Satt8、Satt12、Satt35、Satt105和Satt109这5个位点同时与两年表型值显著关联。明确了由81份材料组成的自然群体的群体结构，并获得了18个与目标性状相关联的SSR位点，其中5个位点同时与两年表型值显著相关，为纤维品质性状的分子标记辅助选择提供依据。

Abstract:

In order to evaluate population structure of cotton resources, 81 samples of cultivated cotton were scaned using the genotyping data of 65 simplesequence repeat (SSR) markers to analyze population structure of these resources. And the related analysis between SSR loci and 8 fiber quality traits was carried out. The results showed that the popuration was divided into 2 subgroups. The related analysis showed that detecting with average value in 2 years 18 SSR loci were associated with the quality traits of cotton fiber. Among them 5 loci were associated with over 2 traits (including 2 traits). And in these 18 loci, Satt8, Satt12, Satt35, Satt105 and Satt109, these 5 loci were simultaneously associated with phenotypic value in two years. The population structure of this natural population consists of 81 samples was clear. And 18 SSR loci associated with the target traits were obtained, among which 5 SSR loci were notably correlated with phenotypic value in 2 years simultaneously. These results had provided basis for molecule marker assisted selection (MAS) in cotton fiberquality trait.
