Mothbean crop has entirely been eliminated from the Punjab and NWFP provinces while it is very, rarely and partially grown in some parts of Sindh and Balochistan provinces of Pakistan with very poor yield production. The main reason for low production of this crop is non-availability of high yielding disease resistant varieties. An effort has been made to collect and screen mothbean germplasm for high yield and resistance to disease. For this purpose a set of 66 mothbean germplasm accessions (collected from various parts of country) was evaluated at Agricultural Research Institute, D.I. Khan during 2004. Most of the accessions were usually found a mixture of several variable genotypes. High yielding desirable plants was screened for further investigations. The materials thus selected were again planted during successive year (2005) in a triplicated randomized complete block design for studying genetic variability, in various morphological trai ts. The results revealed a significant variation in all characters except number of cluster plant-1. The phenotypic co-efficient of variation (PCV) were higher in magnitude than genotypic co-efficient of variability (GCV) indicating the influence of environment on the traits under study. High h2 (86.08 %) was calculated for number of pod plant-1.
