次级群体

次级群体对初级群体的影响主要通过意见领袖实现。

Rural Secondary Group ( RSG ) 's influences on PRG are realized by opinion leader .

次级群体是用于QTL鉴定、精细定位、互作分析、图位克隆、品种改良等的良好材料。

And they were powerful materials for QTL identification , QTL fine mapping , analysis of QTL interaction , map based on clone , variety improvement and so on .

相对于初级作图群体而言，次级作图群体是在相似的遗传背景下进行QTL作图，消除了大部分遗传背景的干扰和QTL之间的互作，提高了QTL作图的灵敏度和准确性。

Comparing with the primary mapping populations , QTL mapping based on SMPs were carried out by the similar genetic background , so most interference of genetic background and interaction of QTLs were eliminated and the precise of QTL mapping were improved .

Prospect of the Secondary Populations in Crop

定位的群体有初级作图群体、次级作图群体和高级作图群体；

QTL mapping populations include the primary mapping population , the secondary mapping population and the advanced mapping population .
