摘要
绿豆象(Callosobruchus chinensis L,)是豇豆属豆类作物重要的仓库害虫。本研究通过抗豆象杂交育种后代 VC1973A/TC1966 F_1F_2和 VC1973A/(VC1973A/TC1966 F_2)BC_1F_1及 TC1966/(VC1973A/TC1966 F_2)BC_1F_1分离群体的遗传分析,发现绿豆抗豆象性状符合3:1的遗传分离规律,证明绿豆对豆象的抗性由1对显性单基因(Aa)控制,抗虫性为显性(A),感虫为隐性(a)。
The bruchid (Callosobruchus chinensis) is a very destructive pest during Vigna legume storage.The segregation populations of VC1973A/TC1966 F_2 and VC1973A/(VC1973A/TC1966 F_2) BC_1F_1 and TC1966/(VC1973A/TC1966 F_2) BC_1F_1 have been evaluated for the genetic behavior of bruchid resistance.We have found the 3:1 mode of segregation for mungbean resistance gene to bruchid.The result showed that the character of mungbean bruchid resistance was controlling by a pair of dominance gene (Aa),with the resistance gene A.
