Abstract:
A field experiment was conducted during Rabi, 2019-20 at Sehore, Madhya Pradesh to investigate the impact of G×E interaction on seed yield of chickpea and identify variability using twenty-five chickpea genotypes in three environments. High variability was observed for majority of the traits in three environments. In late sown condition high GCV and PCV was recorded for number of seeds per plants, number of pods per plants, biological yield per plants, seed yield per plant, empty pods per plant, hundred seed weight. Ample variability available for these traits can be exploited by direct selection. In generally, the late and very- sown crop matured early due to restricted reproductive period and hastened maturity. Characters showing high heritability coupled and high genetic advance as percentage of mean were, plant height, total number of seeds per plants, total number of pods per plants, number of empty pods per plant, 100 seed weight per plants, harvest index, seed yield per plants under late sown environments. Occurrence of high estimates of heritability coupled with genetic advance as per cent of mean for these traits suggest that these traits can be considered as favourable attributes for improvement through selection. Seed yield per plant exhibited a positively and significantly association with number of pods per plant, Biological yield per plant and harvest index. These three traits were followed similar significant trend in all the environmental conditions and plant height, number of seeds per plants in mid-late and very-late sown conditions indicating that results suggested that improvement in these positive correlated traits will accelerate the improve a seed yield per plant.
