ABSTRACT
The study on correlation among quantitative traits and their direct and indirect effect on seed yield in F2 populations (Meha X GJM-1006, Meha X GJM-1008) of mungbean was carried out at Navsari Agricultural University, Navsari during the summer 2014. Correlation analysis revealed that seed yield was significantly and positively correlated with clusters per plant, pods per plant, straw yield per plant and harvest index in F2 population of Meha X GJM-1006 and with seeds per pod, straw yield per plant and harvest index in F2 population of Meha X GJM-1008. It indicates that an association of two characters is not only due to genes but also due to their influence of the environment. The path coefficient analysis on phenotypic basis revealed that pods per plant, days to flowering, days to maturity, clusters per plant, seeds per pod, 100 seed weight, straw yield per plant and harvest index had positive direct effect in F2 population of Meha X GJM -1006 while straw yield per plant, plant height, primary branches per plant, days to maturity, seeds per pod, 100 seed weight, straw yield per plant and harvest index had positive direct effect in F2 population of Meha X GJM -1008 on seed yield, indicated that pods per plant and straw yield per plant directly lead to increase in seed yield both the populations, respectively.
Key words: Mungbean, F2 Population, Correlation coefficient and Path Analysis.
