Abstract:
The present investigation was undertaken to estimate the correlation coefficients among twelve quantitative traits and to study the direct and indirect effects of various yield contributing traits on grain yield by path analysis in thirty five mungbean genotypes at educational and research farm, department of agricultural botany, college of agriculture, Dapoli, dist. Ratnagiri (MS), during rabi, 2018-19 in a randomized block design with three replications. The results of association study revealed that, grain yield per plant (g) showed highly significant and positive correlation at both genotypic and phenotypic levels with number of branches per plant, number of pods per cluster, number of clusters per plant, number of pods per plant and hundred seed weight (g) whereas it was highly significant and positively associated with days to initiation of flowering, number of grains per pod, plant height, pod length and days to fifty per cent flowering at genotypic level only indicating possibility of simultaneous improvement for these traits. Days to maturity had highly significant but negatively correlated with grain yield per plant at the genotypic level. Path analysis revealed that, number of branches per plant, pod length, plant height, number of pods per cluster and number of pods per plant recorded the highest direct effect at in desirable direction. Their association with grain yield was also significant and positive indicating true and perfect association between these traits. Therefor direct selection for these characters would help in isolating high yielding genotypes from highly segregating population.
