Genetic divergence of parents and F2 segregation in grain Amaranths

Twenty six accessions of grain Amaranths (Amaranthus hypochondriacus), including both indigenous and exotic introductions, were evaluated in the rabi season (winter crop, November-March). Based on D² analysis, the accessions were grouped into eleven clusters. Clusters I, II, and III had seven, four,...
