The present study was conducted to determine correlation among different yield contributing traits of mung bean, at Agricultural Research Farm of the NWFP Agricultural University, Peshawar, during the growing season 2004. Correlation was worked out among plant height, days to flowering, days to maturity, total dry weight per plot, yield per plant, 100-grain weight, harvest index and yield per ha. Significant differences were observed among different populations for all the parameters. Correlation analysis revealed that earliness had negative correlation with plant height and dry weight per plot while 100-seed weight and harvest index were recorded to be positively correlated. Dry weight per plot was found to have positive correlation with days to maturity, seeds per pode and plant height while negatively correlated with yield per hectare and harvest index. 100-grain weight showed positive correlation with pods per plant and harvest index while it had negative correlation with days to maturity, seeds pods-1 and plant height. Seed yield per plot was found to be non-significantly correlated with 100-grain weight. Harvest index had significant positive correlation with seed yield per plant while it had significant negative correlation with days to maturity, seed per pode, plant height and dry weight per plot. Similarly, seed yield per plant was positively correlated with pods per plant, yield per ha and harvest index. On the other hand, its correlation with plant height was significantly negative.
