| 摘 要： | 应用AFLP、SRAP、RAPD、SSR及同工酶等标记构建的326个标记位点的白菜遗传图谱和81个DH株系群体,采用M apQTL 5软件对白菜的株高和开展度进行QTL定位。结果表明：通过2年试验,在10个连锁群上共检测到27个QTL,主要分布在R 5、R 10连锁群上：其中控制株高的有11个,控制开展度的有16个;获得2年稳定表达的控制株高的QTL 1个,控制开展度的QTL 3个;各QTL加性效应各不相等,其遗传贡献率为13.3%-29.2%;控制株高和控制开展度的QTL位点表现为紧密连锁或相似的位置,主要集中在R 5连锁群上。

| Abstract: | An AFLP,SRAP,RAPD,SSR and isozyme genetic map with 326 markers and a DH (double haploid lines) population with 81 lines were employed in mapping and analysis of quantitative trait loci(QTL).The number,location,variation explained and additive effect of QTL underlying plant height and plant expansion were determined by using software Map QTL5 in two diffent years.The results were as follow: during two different years,27 putative QTLs,including 11 for plant height,16 for plant expansion were mapped on R5 and ... |
