采用常规品系04-1139与高产多角果品系05-1054构建的F_2代群体为作图群体,运用SSR(Simple sequence repeat)和SRAP(Sequence-related amplified polymorphism)构建分子标记遗传图谱并对甘蓝型油菜单株产量构成因素进行QTL分析.遗传图谱包含200个分子标记,分布于19个连锁群上,总长度1 700.23 cM,标记间的平均距离8.50 cM.采用复合区问作图法(Composite interval mapping,CIM)对单株产量构成因素(单株有效角果数,每果粒数和千粒重)进行QTL分析,共检测到12个QTL:其中单株有效角果数4个QTL,分别解释表型变异为35.64%,12.96%,28.71%和34.02%:每果粒数获得5个QTL,分别解释表型变异为8.41%、7.87%,24.3...

A F2 segregating population for genetic map construction and identification of QTL for seed yield in rapeseed (Brassica napus L.), was developed via crossing a conventional rapeseed line 04-1139 with a high yielding multiple silique rapeseed line 05-1054. A genetic map including 19 linkage groups was constructed with 200 SSR (Simple sequence repeat) and SRAP (Sequence-related amplified polymorphism) markers. This map covers a total length of 1 700.23 cM with an average distance between two adjacent makers of 8.50 cM. Using this map, QTL for the components of yield per plant, such as number of ...
