Genetic diversity in cauliflower (Brassica oleracea L. var. botrytis)

摘要

Genetically diverged twenty genotypes of cauliflower were grouped into five clusters. The intra-cluster value was maximum in cluster IV and minimum in cluster II. The inter-cluster distance was larger than the intra-cluster distance suggesting wider genetic diversity among the genotypes of different groups. The inter-cluster average D2 values indicated maximum distance between cluster I and IV followed by between I and III, and between I and V. Thus, the genetically diverged genotypes could be used as parents in hybridization programme for getting desirable segregants.
