Values in parenthesis are number of accessions forming cluster (group of accessions resembling each other for their phenotypic performance under drought stress for the ten traits and hence with low intra-cluster divergence). Bold values refer to intra-cluster distance. The χ2 significance was calculated using CHIINV functions in Microsoft excel with n-2 degree of freedom, where n is the number of traits considered for clustering which in this case were 10 traits.
