genetic diversity in dahlia (Dahlia variabilis)

Multivariate analysis of divergense among 23 varieties of dahlia for nine developmental chararters led to their grouping into of clusters. The first two dusten had four varieties, the next two cluster had three varieties earh, three cluster comprised two varieties each, and the last three clusters induded one variety each. Thus, these three varieties were more diversed than others. Based on duster means, characters like Rower weight, flower diameter, number of flower and shoots/plant, and length or noral stalk were the major rarton or differentiation among these 23 varieties. The intercluster D² values ranged from 74 to 3033, suggesting very little domestiration in this crop.
