Response of mungbean C.Vs were studied under agroclimatic condition prevailing in Peshawar, planted in August 1983 and May 1984. Significant differences were observed for days to pod formation, number of branches, pods per plant, and grains per pod, pod length and yield per plant. Variety M-21-20 and M-13-1 maintained superiority in yield either sown in August or May. Days to pod formation showed positive association with pods per plant, grains per pod, pod length and yield per plant, except pod per plant and grains per pod in 1984, where negative correlation was observed. Positive correlation was noted among branches per plant, Pods per plant and yield per plant. However branches per plant associated negatively with grains per pod and pod length. Pods per plant showed positive relationship with grains per pod, pod length and yield per plant. Significantly positive association of grains per pod was observed with yield per plant, while correlation with pod length was negative. Pod length associated positively with yield in 1983 while this relationship was negative in 1984.
