Abstract:
A set of 75 genotypes of barnyard millet including germplasm accessions, released cultivars and advanced genetic material were assessed for character associations and Ward’s hierarcheal clustering with Euclidian distance using 11 agro-morphological traits during studied kharif 2023 in an Alpha Lattice Design with two replications. The analysis of variance shown the presence of significant variations among the genotypes for all the traits evaluated. In correlation studies, grain yield exhibited significant and positive association with days to maturity, plant height and panicle length at both genotypic and phenotypic levels. The traits which are exhibiting positive significant correlation on grain yield can be considered as important traits to be included in the selection to achieve genetic improvement of grain yield in barnyard millet. The Ward’s hierarcheal clustering of genotypes with Euclidian distance has generated four main clusters separated at similarity index of 300 Euclidian distances. Similarly, K-means analysis generated four clusters containing 21, 31, 13 and 10 genotypes in respective clusters I, II, III and IV. Cluster II has maximum number of genotypes followed by Cluster I, Cluster III and Cluster IV.
