| 摘 要： | 利用遍布全基因组的21个SSR分子标记,对小麦雌性不育系XND126与1201、802、60个普通小麦品种(系)组成的三个品种(系)群体进行群体结构的评估,发现在三个群体中都存在群体结构.对消除群体结构后的三个亚群体中各标记的连锁不平衡值(linkage disequilibrium value)进行比较.结果表明,群体大小影响标记与雌性育性位点间的LD值.基于对小麦雌性育性taf1位点初步定位的信息.对2DS染色体上30个SSR分子标记的LD研究显示,Xgwm71、Xwmc25、Xgwm515、Xcfd36同样与原标记Xgdm35等具有较大的LD值,可能与taf1密切相关.获得这些较大LD值的标记(Xgwm71、Xwmc25等),为taf1位点的精细定位做出了充分的准备. |

| Abstract: | In this article,we evaluated the population structure in three variety population consisted of a female sterile line 126 with 120,180 and 260 varieties of wheat by SSR analysis,the study showed that sub-population existed in the three populations.The linkage disequilibrium(LD) value were compared in three sub-populations after the elimination of population structure,it was found that the different size of population influenced LD value of marker with quantitative trait locus.Based on the information of fema... |
