Abstract
Twelve chickpea genotypes were tested to assess variability, heritability, correlations and direct and
indirect effects between yield and yield components. Maximum phenotypic and genotypic coefficient of
variation was recorded for number of seeds per plant (33.8, 32.4), number of secondary branches per
plant (30.3, 29.6), number of pods per plant (25.6, 24.7) and 100 seed weight (23.0, 22.7) respectively .
High heritability coupled with high expected genetic advance as percent of mean were estimated for
number of secondary branches per plant, number of pods per plant and 100 seed. Path coefficient
analysis (seed yield as a dependent variable) revealed that seeds per plant followed by biomass yield,
days to maturity and 100 seed weight had exerted positive direct effect on seed yield. To conclude,
number of seeds per plant, biomass yield, 100 seed weight and days to maturity are important
parameters for selecting maximum yielding genotypes in chickpea.
