Abstract

In this investigation, magnitude of genetic divergence was
studied in 25 vegetable amaranth using D2 statistics. The
genotypes were grouped into 5 clusters with the highest
number of genotypes (10) in cluster V. High inter-cluster
distance indicated that genotypes of cluster III were far
diverged from the genotypes in cluster I, II and IV,
respectively. The PCA indicated prominent contribution
of protein, foliage yield, leaf area and Zn content towards
total divergence. Cluster I and Cluster III could be considered
for excellent antioxidant and nutrients and high foliage
yield. Cluster II for nutrients, cluster IV for antioxidant and
nutrients and cluster V for antioxidant, nutrients, and
foliage yield. Based on inter-cluster distance, intra-cluster
and scatter diagram, the genotypes AA28, AA15, AA19,
AA26, AA9 and AA17 would be potential genotypes for
generating transgressive segregants.
