Abstract
One hundred accessions (50 from India and 50 from exotic sources) of grain amaranth (Amaranthus hypochondriacus) germplasm were grown in complete randomised block design. Data were recorded on six quantitative and two qualitative characters. Wide range of means was observed for all the characters. All the genotypes irrespective of their place of collection were grouped into 10 different clusters. Clusters I, VII, VIII, IX and X had high genetic distance with all other clusters. Correlation and path analysis revealed the significance of inflorescence; length, no. of leaves and plant height for selecting better yielding genotypes.
