小麦矮秆种质系山农342-9矮秆基因的分子标记定位
Molecular Mapping of Rht Gene in Wheat Dwarfing Germplasm Line Shannong 342-9
摘要
Abstract
The GA sensitivity , genetic characteristics of dwarfing traits of Shannong 342-9 were identi-fied and analyzed by field investigation .And the dwarfing gene was located by molecular maker technology . The results showed that Shannong 342-9 was insensitive to GA , and its dwarfing gene was a recessive gene on chromosome 6B.Two SSR markers linked to dwarfing gene , Xwmc398 and Xgwm508, were identified from 2 606 pairs of primers.And their genetic distances with dwarfing gene were calculated with F 2 segregation population,which were 1.2 cM and 8.1 cM respectively.关键词
