摘要
对19个加工类型黄瓜品种的7个品质性状进行了主成分和聚类分析。结果表明:19个品种分为产量、形态和品质3个主成分因子,其主成分的累计贡献率达89.81%,而且基本上可描述7个品质性状的遗传变异。当类平均距离为1.035时,19个品种被聚为短果和长果2种类型,而当类平均距离为0.942时,19个品种被聚为短果中等品质、短果优质和长果高产3种类型。
Principal component analysis and cluster analysis on 7 quality characters of 19 pickling cucumber varieties were conducted. Three factors, yield, morphology (fruit) and quality accounted for 89. 81% of total variation and therefore, those three factors can be used to explain genetic variation of 7 quality characters. 19 varieties were clustered into two types which were short and long fruit, when average distance was 1. 035 and three types which were short fruit with good quality, short fruit with excellent quality and long fruit with high yield, when average distance was 0. 942.
