This study sought to evaluate the genetic variation among forty-nine different genotypes of barley, comprising both exotic and indigenous lines, In addition incorporating four check varieties (BH 902, RD 2552, 2035, DWRB 92). The analysis variance unveiled noteworthy discrepancies across a range traits, except for 1000-seed weight. Block-wise indicated no significant differences, suggesting comprehensive inclusion factors influencing seed yield. coefficient was highest number productive tillers per plant (GCV) at 16.62, followed by peduncle length 14.83, with phenotypic (PCV) values 17.14 15.33, respectively, minimal environmental influence on trait expression. non-hierarchical Euclidean cluster grouped all into eight clearly defined non-overlapping clusters. Cluster III comprised (17), whereas VI contained only one genotype (IBYT-HI-4). Intra-cluster distance revealed I as having value, Clusters V, III, VIII, VII. Notably, inter-cluster distances were notably high between clusters II (59.26) VIII (49.95), potential obtaining superior segregants through mating these
