Abstract:
The present experiment was conducted at research farm of All India Coordinated Research Project on Chickpea, R.A.K., College of Agriculture, Sehore (M.P.). The experimental material consisted of 28 diverse genotypes including 19 desi and 9 kabuli genotypes of chickpea laid out in Randomized Complete Block Design with two replications, were tested in consecutively two year under different sowing condition to provide optimum, normal and high stress conditions to the genotypes and genetic parameters, correlations observed. The analysis of variance is clearly indicating the impact of environment, G×E interactions observed significant for all traits. All the traits affected severely under stressful condition, because of high temperature. The days to flower initiation reduced by 5 days, days to 50% flowering reduced by 3 days, Days to pod initiation reduced by 17 days, plant height reduced by 17(cm), Days to maturity reduced by 23 days, number of pods per plant reduced by 33, number of empty pods per plant reduced by 1.15, number of seeds per plant reduced by 20.68, biological yield per plant reduced by 9.91(g), harvest index reduced by 6.91, hundred seed weight reduced by 4.78 (g), and seed yield per plant reduced by 5.06 (g) in normal to stress condition. PCV and GCV and heritability was almost high everywhere. The seed yield per plant was noticed significant and positively associated with number of pods per plant, number of seeds per plant, biological yield per plant, harvest index, hundred seed weight and pollen fertility while its significant and negatively correlated with days to flower initiation, days to 50% flowering, days to pod initiation in all the environmental conditions. For increasing seed yield due importance should be put on number of pods per plant, number of seeds per plant, biological yield per plant, harvest index, hundred seed weight and pollen fertility.
