摘要： 对56个冬瓜品种的13个性状进行了遗传相关和通径分析,结果表明,瓜长、瓜肉致密性、横径、单瓜重与总产量有密切关系,瓜肉致密性是构成冬瓜单瓜重和总产量的主要性状,瓜长对产量的贡献最大。瓜长、瓜肉致密性与单瓜重呈极显著正相关,中腔与单瓜重呈极显著负相关。

Abstract: The correlation and path analysis of 13 characters of wax gourd were carried out.The results showed that the length of fruit,compactness,width and average weight of fruit existed evident relativity to yield.Compactness was the most important component factor to the fruit weight and total yield.Fruit length contributed the most to the yield.Significant positive correlation were observed between fruit weight,fruit length and compactness,while significant negative correlation were observed between cavity of fruit and fruit weight.

Key words: Wax gourd, Genetic relativity, Path analysis
