瓠瓜种质资源主要果实性状的主成分与聚类分析
|
摘要
对119份瓠瓜种质的8个主要果实性状进行了主成分分析与聚类分析。结果表明,119份瓠瓜种质的ShannonWeaver多样性信息指数在0.394 8~2.063 6之间,8个果实性状存在较广泛的遗传多样性,其中以果实形状、皮色和单瓜质量的多样性最丰富。主成分分析结果表明,第一、第二、第三、第四主成分的贡献率分别为37.24%、23.33%、14.71%、9.44%,其累计贡献率达到84.72%。聚类分析结果表明,可以将119份瓠瓜种质分为两大类群,分别包含62份和57份种质,其中第一大类群在品质和外观方面均表现较好,可作为瓠瓜育种的基础材料。
This paper carried out principal components and cluster analysis of 8 main fruit characters from 119 bottle gourd germplasm resources.The results showed that Shannon-Weaver diversity information index was between 0.394 8-2.063 6.There were wide genetic diversities in 8 fruit characters,among them fruit shape,peel color and single fruit weight had the most abundant genetic diversities.The results of principal components analysis showed that the first,second,third and fourth principal component contribution rates were 37.24%,23.33%,14.71% and 9.44%,respectively and their cumulative contribution rate reached 84.72%.The results of cluster analysis indicated that 119 materials of bottle gourd germplasm resources could be divided into 2 groups,including 62 and 57 germplasm resources,respectively.The first group had better quality and appearance,and could be used as basic material for breeding of bottle gourd.
