利用有棱丝瓜“粤优大肉”和普通丝瓜“株杂二号白丝瓜”高代选系为亲本建立种间杂交F1、F2、B1、B2及部分反交F’2、B’2，对果棱、果把形状、果皮颜色及日开花时间性状的遗传特性进行分析。结果表明：果棱性状为1对主基因控制的质量性状，同时受微效基因控制，有棱为部分显性；丝瓜果皮颜色、果把形状、丝瓜日开花时间均为数量性状，符合加性－显性遗传模型，以加性效应为主，控制性状的最少基因数目分别为2对、1对、3对。广义遗传力及狭义遗传力都非常高，在育种中可以在早期世代对性状进行选择。4个性状都不受细胞质遗传影响。

The inheritance of three fruit traits ( fruit ridge,carpogodium shape,fruit peel color ) and daily anthesis in Luffa was studied by using interspecific populations derived from Luffa acutangula cv.Yueyoudarou and Luffa cylindrica cv.Zhuzabai No 2.The fruit ridge was partially dominated and controlled by one major gene with other minor genes.The traits of fruit peel color,carpogodium shape and daily anthesis were all quantitative?ly inherited and fit the pattern of additive-dominance mode. The minimum gene numbers for three traits were 2,1 and 3,respectively.The general inheritabilities and narrow inheritabilities of the three traits were all very high,indicating that selection in breeding can be carried out in early generations.There was no cytoplasmic in?heritance in the four trait studied.
