【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 F₁F₂和 VC1973A/（VC1973A/TC1966 F₂）BC₁F₁及 TC1966/（VC1973A/TC1966 F₂）BC₁F₁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）。更多还原

【Abstract】 The bruchid （Callosobruchus chinensis） is a very destructive pest during Vigna legume storage.The segregation populations of VC1973A/TC1966 F₂ and VC1973A/（VC1973A/TC1966 F₂） BC₁F₁ and TC1966/（VC1973A/TC1966 F₂） BC₁F₁ 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.更多还原
