辣椒种质资源主要表型性状的聚类分析

Cluster Analysis Based on Main Morphologies in Hot Pepper

通过对92份辣椒材料表型性状进行聚类分析,结果表明,92份辣椒种质间的距离系数分布在1.25～33.37之间,在14的距离系数处,可将92份辣椒材料分为七大类群,将一些来源相同或相近的地方材料聚在一起,其辣椒多样性分布和种质来源地具有一致性。

The morphologies of 92 hot-pepper accessions were analyzed by cluster analyses in the study. The results showed that distance coefficients ranged from 1.25-33.37 among the 92 accessions. The accessions were divided into 7 groups at 14 of genetic distance. The genetic diversity distribution of some accessions was related to the source place, and the accessions collected from similar areas were clustered together.
