摘　　要：以60份樱桃番茄品种为试材,利用SPSS软件对其种质资源的主要品质性状进行了主成分分析和聚类分析。结果表明:经主成分分析将12个品质性状综合成为5个主成分因子,其累积贡献率可达80.234%以上;经聚类分析60个樱桃番茄品种可划分为8类,各类别间品质和遗传距离有较大差距。研究结果为番茄品质鉴定改良和品质育种提供了科学参考。Taking 60 cherry tomato varieties as materials, their principal component and cluster analysis of germplasm quality traits were analyzed by using SPSS software. The results showed that 12 traits were classified into 5 principal components and their additive contributing rate came up to 80. 234%; 60 cherry tomato varieties were divided into 8 categories through cluster analysis,and there was a wide genetic distance and quality between each category. The results could provide the basis for evaluation of tomato main quality traits the quality breeding.
