Genetic Diversity in Early Cauliflower (Brassica oleracea Var. botrytis L.) Germplasm

An experiment was conducted to study genetic divergence in 51 genotypes of cauliflower. Data was recorded for 16 quantitative characters. The genotypes were grouped into 14 clusters. A majority of the genotypes grouped together in Cluster 14 (with 14 genotypes), followed by Cluster 12 (with 8 genoty...
