摘要
以收集的国内外37份南瓜种质资源为试验材料,对其形态学性状的遗传多样性参数进行调查和统计分析。结果表明:30个形态性状的变异系数较大(10.35%～69.44%),不同性状在不同的材料之间表现出不同程度的形态学多样性。其中突出的是叶形、瓜形、瓜形指数、商品瓜横切面形状、老瓜肉色、种皮色、商品瓜横径等性状。变异系数最大的性状是瓜形(69.44%)。此外,南瓜种质资源的其它一些性状也存在着许多明显的差异。
In this paper, the morphological traits of 37 pumpkin germplasm resources were stualect ann analyzed. It showed that the CV of 30 traits were bigger （10.35% -69.44%）. There are different extent of diversity on morphology of the different varieties, especially in the aspects of leaf shape, melon shape, coefficient of melon shape, cross section shape of the ripe melon, flesh color of ripe melon, color of seed and width of ripe melon. The biggest CV is melon shape, which goes up to 69.44%. In addition, many distinct differences are also found in some other traits.
