Background: To characterize Dolichos bean germplasm collected from different sources based on agro-morphological characteristics and identify suitable Bean lines used as Vegetable purpose in the hilly region of Tripura, field experiment was carried out at the Experimental Farm of College of Agriculture, Tripura at Lembucherra, West Tripura, during the Period of August 2023 to February2024.

Methods: The experiment was conducted using a Randomized Complete Block Design (RBD) with 25 treatments and 3 replications. The germplasms were sourced from various regions of Tripura and the Indian Institute of Vegetable Research (IIVR).In the present study 6 qualitative characters and 13 quantitative characters were recorded from 25 genotypes.

Results: All the 25 Dolichos bean genotypes under study showed wide range of variations in the qualitative and quantitative characters including Pods per plant revealed significant variation, six distinct pod colors, four flower bud colors, four standard petal colors, three wing petal colors, four keel petal colors and three seed colors have been observed.

Conclusion: The identification of superior genotypes such as Khowai Local-2, VRSEM-1, and Brahmanpuskarini Local-4 is particularly noteworthy. These genotypes demonstrated exceptional performance in terms of yield and other agronomically important traits, making them strong candidates for inclusion in future breeding programs. Their potential to serve as parental lines in hybridization efforts could lead to the development of high-performing, location specific cultivars tailored to meet the needs of both farmers and consumers.
