| 摘 要： | 以自育高品质中长绒棉品种（新陆中9号提高系）9-1696为母本，与主栽品种中棉所35为父本配置单交组合，筛选出12对SSR引物在F2群体和B1群体进行纤维长度、整齐度、比强度和伸长率4个纤维品质性状的QTL分析,采用区间作图法（LOD>2.0），在F2群体中检测到6个与纤维品质性状连锁的QTL位点。其中，检测到纤维长度、纤维整齐度、伸长率各1个QTL位点，比强度检测到3个QTL。在B1群体中检测到2个QTL，分别与比强度和纤维长度连锁。

| Abstract: | The parents used are 9-1696 and CCRI 35,that 9-1696 is high quality mid-length fiber cotton by ower-breeding and CCRI 35 is major-plant in Xinjiang.Based on the cross and 12 SSR makers information of 180 plants of F2 population and 135 plants of B1 population,the inheritance of 4 fiber quality traits were studied by the methods of QTLs.The major results are as follows:Six QTLs were detected and linked to four fiber quality traits by using F2 population and interval mapping method(at the level of LOD>2).One QTL was linked to Fiber length;three QTLs were linked to strength;one QTL was linked to uniformity,one QTL was linked to elongation.Two QTLs were identified based on B1 population,and linked to fiber length and strength respectively. |
