Morphological characterization and diversity estimation are essential in plant breeding. In this endeavor, the researcher performed a visual assessment of 18 phenotypic DUS listed traits of 32 Kabuli chickpea genotypes in rabi 2021-2022. Nine traits were monomorphic, four traits were dimorphic, while five traits were polymorphic. Shannon’s diversity indices were estimated using Microsoft excel. The index ranged from 0.00 to 1.06, with a mean value of 0.36. Seed size (g) obtained the highest value of the 32 genotpyes, few were unique as they could be distinguished based on a single trait, while the majority were very closely related. Cluster analysis revealed that the 32 genotypes were grouped into two major clusters—similar genotypes concerning different traits clustered in the same clusters and vice versa.
