    Abstract:

    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.
