Correlation Study on Morphological and Yield Parameters of Mungbean (Vigna Radiata)

The present study was conducted to determine correlation among different yield contributing traits of mungbean, 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 plot1, yield plant1, 100-grain weight, harvest index and yield ha1. 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 pod1 and plant height while negatively correlated with yield per hectare and harvest index. 100-grain weight showed positive correlation with pods plant1 and harvest index while it had negative correlation with days to maturity, seeds pods1 and plant height. Seed yield plot1 was found to be non-significantly correlated with 100-grain weight. Harvest index had significant positive correlation with seed yield plant1 while it had significant negative correlation with days to maturity, seed pod1, plant height and dry weight per plot. Similarly, seed yield per plant was positively correlated with pods plant1, yield ha1 and harvest index. On the other hand, its correlation with plant height was significantly negative
