Abstract

Twenty-five phenologically and physiologically different mungbean genotypes were involved in field experiments during kharif seasons of 2000 and 2001 to elucidate the relative efficacies of pnenological as well as physiological parameters during pre and post flowering periods on seed yield. Through estimations of correlations, further partitioning of the correlations into direct and indirect effects, regression, and per cent association of the traits during pre and post flowering periods with seed yield it was concluded that yield structure of mungbean was related differentially with physiological traits during pre and post flowering periods. During pre flowering period, leaf area duration and relative growth rates of leaf and total plant and days to flowering had major influence on yield. During post flowering period, dry matter allocation in pods and total plant, days to podding and leaf area duration had their definite roles in influencing the seed yield mungbean genotypes.
