Despite of crops high demand, only less breeding work was done and less attention has been paid for genetic improvement of quality attributes. Before developing any superior variety with superior quality, it is necessary to compare the performance of the genotypes with best performing variety, aim of this study is to identify the superior quality genotypes. During Kharif, 2019, twenty-four genotypes and one check variety, were evaluated in Completely Randomized Block Design replicated thrice at three environments representing three Telangana agroclimatic Zones: PG Research Block, COH, Rajendranagar, Hyderabad (Southern Telangana Zone), progressive farmers field at Karimnagar (Northern Telangana Zone) and JVR HRS, Malyal, Mahabubabad (Central Telangana Zone). Significant differences were observed between genotypes. Protein content, crude fibre content in the pod and gum content in the seed's endosperm were estimated. Protein content was found highest in genotypes IC-28287 (23.86 percent) and IC-13348 (23.55 percent). The genotype IC-9077-P1 had the highest crude fibre content (4.36 percent), whereas IC-28269 had the lowest fibre content (8.71 percent). The gum content in cluster bean genotypes IC-103295 (33.02 percent) and IC-9077-P1 (32.17 percent) was determined highest. As a result, these germplasm can be utilized as such or can further be subjected to further selection or breeding programmes to develop a desirable variety of cluster bean suitable for rainfed environments.

Cluster bean, crude fibre content, protein content, gum content.

In any selection programme, the mean performance of germplasm for individual trait is an important criteria for removal undesirable types. This demonstrated that the material examined might serve as a potential source of quality traits such as protein content was found highest in genotypes IC-28287 (23.86 percent) and IC-13348 (23.55 percent), genotype IC-9077-P1 had the highest crude fibre content (4.36 percent), whereas IC-28269 had the lowest fibre content (8.71 percent). The gum content in cluster bean genotypes IC-103295 (33.02 percent) and IC-9077-P1 (32.17 percent) was determined highest. As a result, these germplasm can be utilized as such or can further be subjected to further selection or breeding programmes to develop a desirable variety of cluster bean with desirable quality traits.
