Abstract
Green gram (Vigna radiata L.) is an important pulse crop grown in India. The entire success of plant breeding programme of any crop largely depends on the wide range of variability present in that crop. It is the range of genetic variability in respect of important economic characters present in the population upon which is based on the effectiveness of selection. Correlation studies measure only mutual association between two traits and it does not imply the cause and effect of relationship. Path analysis is a standardized partial regression analysis, which further permits the partitioning of correlation coefficient in to components of direct and indirect effects of independent variable on the dependent variable.
The present investigation was carried out with thirty diverse mungbean (Vigna radiata L. Wilczek) genotypes for ten characters with three replications in the field of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra state during the kharif, 2016-17 for the estimation of genetic variability parameters, correlation coefficient and path coefficient analysis. The higher values of GCV and PCV observed for almost all the characters studied. High estimates of heritability in broad sense were recorded for plant height (0.97), grain yield per plant (0.91), days to 50 percent plant flowering (0.89), 100 seed weight (0.85), plant stand at harvest (0.84), number of pod per plant (0.84), number of seed per pod (0.78), days to maturity (0.29) and number of branches per plant (0.20). High genetic advance observed for plant stand at harvest (67.48) plant height (16.72), days to 50 percent flowering (6.37), number of pod per plant (5.44). The lowest magnitudes of genetic advance were reported for number of branches per plant (0.44), 100 seed weight (0.86), number of days to maturity (1.35), number of seed per pod (2.31), grain yield per plant (4.70) and number of pod per plant (5.44). The yield per plant was highly significant and positively correlated with plant stand at harvest, plant height, number of branches per plant, number of pod per plant, 100 seed weight, number of seed per pod, Path coefficient analysis indicated high direct effect on days to 50% flowering, number of branches per plant, number of pod per plant.
