Components of variance analysis in chickpea

Components of variance and other genetic parameters for ten agronomic traits in a 6 x 6 diallel cross set without reciprocals were analyzed in chickpea. Additive component (D) was predominant for days to flower initiation, plant height, 100seed weight and harvest index whereas for days to pod initiation, number of branches, number of pods, plant biomass and grain yield, showed pre ponderance for the non-additive components (H₁, H₂). Number of seeds per pod was found to be governed by both additive and non-additive components. The high heritability (narrow sense) estimates were noticed for days to flower initiation, harvest index and 100–seed weight. Partial dominance was observed for days to flower initiation, plant height and harvest index whereas over-dominance was observed for days to pod initiation, number of branches, number of pods, number of seeds per pod, plant biomass, grain yield and 100 – seed weight.
