用新化白苦瓜做母本P（2感虫品种）,广西野生苦瓜做父本P（1抗虫品种）进行杂交获得F1代。F1代分别与P1、P2回交获得两个回交世代B1和B2,同时F1代自交获得F2代。利用以上六个世代进行田间试验,在田间自然虫源条件下,对苦瓜植株果实抗虫性的遗传进行了研究,结果表明苦瓜对瓜实蝇的抗虫性是数量性状的遗传,符合加性-显性遗传模型,抗瓜实蝇的遗传以加性效应为主。

Xinhua White bitter gourd P1 （insect-resistance variety ） was used as a female parent and wild bitter gourd P2（susceptible variety） was used as male parent, the F1 generation was made.Then F2, B1, B2 were all obtained by self-breeding and backcross. Insect-resistance genetics to fruit flies （Bactrocera cucurtitae） were investigated by using 6 generations in the field under natural infestation. The results showed that insect-resistance genetics to fruit flies （Bactrocera cucurtitae） are appropriate to additive-dominant model and the additive effects were more important than the dominant effects.
