Estimates of direct and indirect effects among yield, yield contributing and quality traits in Kabuli chickpea

Abstract

Present study was conducted to investigate direct and indirect effects and selection criteria among the thirty genotypes of kabuli chickpea. The experiment was carried out in the Regional Agricultural Research Station, Nandyal, Andhra Pradesh during rabi at 2016-17. The genotypes were evaluated in a Randomized Block Design having three replications under rainfed and irrigated conditions. The most important characters accounting for cause and effect relationships on seed yield of kabuli chickpea were shoot biomass and harvest index under rainfed as well as irrigated conditions through their high direct effects as well as high indirect contributions via other traits viz., days to 50 percent flowering, number of primary branches, number of pods per plant and number of seeds per plant under rainfed condition. While, days to 50 percent flowering, days to maturity, number of pods per plant and number of seeds per plant under irrigated condition. Therefore, selection for high shoot biomass and harvest index would leads to the high seed yield.
