ABSTRACT
Genetic variability and character association were studied in 60 mungbean genotypes for different morpho-physiological characters during summer, 2013. Highest GCV and PCV were observed for number of branches per plant, plant height, total pod weight per plant, harvest index, canopy temperature difference, membrane stability index and necrosis. Highest genetic advance as per cent of mean was recorded for necrosis, membrane stability index, plant height, number of branches per plant, biomass, total pod weight per plant, total chlorophyll content, number of pods per plant, seed dry weight per plant, harvest index and canopy temperature difference. High heritability was recorded for photochemical efficiency followed by days to maturity, membrane stability index, plant height, seed dry weight per plant, total chlorophyll content , total pod weight per plant, biomass, number of seeds per pod, days to first flowering, 100 seed weight, days to first pod, flower retention, number of branches per plant. Hence, direct selection may be exercised for improvement of these traits. Estimates of correlations revealed that seed yield had positive and significant correlation with flower retention, number of pods per plant, number of seeds per pod, biomass, pod weight per plant, seed weight per plant, harvest index, canopy temperature difference, photochemical efficiency, membrane stability index, total chlorophyll.
Key words: Mungbean, Variability, Heritability, Genetic Advance and Correlation
