不同菜心品种产量及品质性状聚类分析

采用系统聚类法对41个菜心商品品种的形态、产量和品质性状进行聚类分析。结果表明，41个菜心品种在植株形态和产量性状上分为3个类群，每个类群又均可分为两个亚群，其中Ⅲ-1砸群5个品种的株型和产量性状表现优良。41个菜心品种在品质性状上分为3个类群，第1类群又可分为两个亚群，其中第Ⅱ、第Ⅲ类群5个品种的综合品质性状表现优良。菜心各品种在熟性、植株形态、产量和品质等方面差异明显，在实际中需根据生产目标选择适宜的品种。...

flowering Chinese cabbage; yield; quality; cluster analysis
Cluster analysis on plant morphology, yield and quality characters of 41 commercial flowering Chinese cabbage varieties was made. The results showed that, 41 flowering Chinese cabbage varieties were divided into 3 groups according to morphology and yield characters. Each of these 3 groups could further be divided into 2 subgroups, among which 5 varieties in Ⅲ-1 subgroup performed well on plant morphology and yield characters. 41 flowering Chinese cabbage varieties were divided into 3 groups according to quality characters, among which Group Ⅰ could further be divided into 2 subgroups. 5 varieties in group Ⅱ and Ⅲ performed well on integrated quality characters. The maturity, morphology, yield and quality of flowering Chinese cabbage varieties were obviously different, thus suitable varieties should be chosen according to production aims in practice.
