结果表明：感病品种根系分泌物处理的黄瓜枯萎病发病早，接种后第15天病株率显著高于对照，至第20天时病株率与对照相近；而抗病品种根系分泌物处理的病株率一直显著小于对照。

The analysis of Wr+Vr showed that the additive effect was major and the susceptibility was partially dominant.The inheritance of resistance in the highly resistant accessions(Calhoun Gray、Sugerlee) to race1 conform to a single dominant gene conditioned the resistance and there was significant correlation between the genes controlling the characters.

试验结果表明：西瓜对枯萎病抗性是由隐性多基因控制，其遗传符合加性-显性模型，加性效应比显性效应更为重要，且感病对抗病表现为部分显性，显性方向指向增效，隐性基因为减效，在所有亲本中所携带的隐性基因比显性基因多。
