| 摘 要： | 甘蓝型油菜的白花性状是一种有用的指示性状,本研究以甘蓝型白花油菜及其分离群体为材料,对甘蓝型油菜的白花性状的遗传规律进行了研究。结果表明,甘蓝型油菜的白花性状受1对不完全显性基因控制。利用集团分离法(BSA)对白花基因进行AFLP分析,在256对AFLP引物中共获得6个与白花基因紧密连锁的分子标记。EA11MC04与EA12MC01为基因两侧最近的分子标记,其遗传距离分别为0.8,1.0 cM。

| Abstract: | White character is a useful marker trait in Brassica napus L,white petal rapeseed and their segregation populations were used as experiment materials to study the inheritance of white petal traits.The results showed that the white petal color character was controlled by one pair of incomplete dominant gene.Bulked segregation analysis(BSA)was employed to identify the amplified fragment length polymorphism(AFLP)markers linked to the white petal gene,from a survey of 256 AFLP primer combinations,six AFLP markers tightly linked to the white petal gene were identified.In which EA11MC04 and EA12MC01,the two closest markers,were located on either side of the white petal gene at a distance of 0.8 and 1.0 cM,respectively. |
