Abstract
Mothbean crop has entirely been eliminated from the Punjab and NWFP provinces while it is very rarely and partially grown in some part 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 out mothbean germplasm for high yield and resistance to disease. For this purpose a set of 66 mothbean germplasm accessions (collected from various part 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 were 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 traits. The results revealed a significant variation in all the characters except number of clusters per plant. The phenotypic co-efficient of variation (PCV) were higher in magnitude then genotypic co-efficient of variability (GCV) indicating the dominant influence of environment on the traits under study. High h2 (86.08 %)was calculated for number of pods per plant.
