| 摘 要： | 采用来自Charleston×东农594的143个重组自交系(RILs),构建了1个含有20条连锁群的大豆遗传连锁图谱,对大豆营养生长期、生殖牛长期、发育期进行QTL分析,以期探索大豆生育期相关基因的遗传机理.结果表明:采用复合区间作图法共定位了 6个显著影响营养生长期的QTL位点,分布在A1、H、K、N连锁群上;定位了6个显著影响大豆生殖生长期的QTL位点,其中4个,reA1-2、reH、reK、reN也同时控制营养生长期的长短;在整个生育期定位到8个QTL位点,有5个位点能解释20%以上的表型变异.

| Abstract: | In order to sludy on genetic mechanism of growth period in soybean,a genetic linkage map of 20 linkage groups was constructed using 143 recombinant inbred lines( RILs)from soybean. Charleston × Dongnong 594. Combining the map with composite interval mapping method,6 QTLs controlling vegetative period were mapped on linkage groups A1 ,H,K,N; 6 QTLs for reproductive period were identified,of these, reA1-2, reH, reK, reN also affecting vegetative growth; in whole growth period,8 QTLs significantly affecting maturity were identified, among them,5 QTLs could explain more than 20% phenotypic variation. |
