The aim of present study was to estimate the genetic variability, genetic advance and correlation between yield and yield contributing traits along with direct and indirect effect of yield component on yield through path analysis from data collected on 20 chickpea genotypes. Seed index, seed yield per plant, harvest index, number of seeds per plant showed high genotypic and phenotypic coefficients of variation. Seed index, days to 50% pod setting, plant height, days to 50% flowering, seed yield per plant, days to maturity expressed high heritability. Whereas Harvest index showed high genetic advance. Seed index, seed yield per plant, harvest index, number of seeds per pod and plant height expressed high genetic advance as percent of mean. Seed yield per plant significantly positive correlated with harvest index and number of secondary branches per plant at genotypic and phenotypic levels. Harvest index, biological yield, days to 50% pod initiation showed high positive direct effect with seed yield per plant at genotypic and phenotypic levels. Thus, these traits are identified as the efficient and potential for the improvement of chickpea productivity in the present experimental materials.

“…Significant and positive association of seed yield was also observed between number of pods per plant in E1 and plant height in E3. Positive significant association of these traits was also supported by the findings of Rathod et al (2020) and Kumar et al (2020) for number of pods per plant; Janghel et al (2020) and Tsehaye et al (2020) for plant height and Sidramappa et al (2010) for duration of reproductive phase.…”

“…In E3, higher genetic variability was observed for swelling capacity, seed yield, number of pods per plant, iron content and leaf area index. Higher genetic variability for these traits was also reported by several researchers[Dar et al (2020) andRathod et al (2020) for seed yield;Fasil et al (2020) andRathod et al (2020) for number of pods per plant;Jayalakshmi et al (2018) for iron content; Johnson et al (2018) and Tripathi et al (2012) for swelling capacity and hydration capacity].…”

“…In this study leaf area index, number of branches per plant, number of pods per plant, plant height, harvest index, seed yield, 100-seed weight, hydration capacity, swelling capacity, cooking time and iron content exhibited high heritability and high to moderate GAM in all three sowing dates. Fasil et al (2020) for number of pods per plant, Kumar et al (2020) for seed yield, Tripathi et al (2012) for swelling capacity and Rathod et al (2020) for plant height and 100 seed weight reported high heritability and moderate to high genetic advance. Phenological traits viz., duration of reproductive phase in E1, and duration of flowering, days to first flowering, days to 50% flowering and duration of vegetative phase in E2 recorded high heritability but low genetic advance.…”

The study was conducted during rabi 2020-2021 at RARS, Nandyal, Andhra Pradesh to determine relationships among phenological traits, seed yield, yield attributes and quality traits in chickpea under different dates of planting. In the present study, in all three dates of planting, seed yield recorded highly significant and positive association with two phenological traits viz., duration of reproductive phase and duration of flowering. However, these traits were influencing seed yield via other contributing characters like days to first f lowering, duration of vegetative phase, leaf area index, days to maturity, plant height, number of branches per plant, number of pods per plant, 100 seed weight and harvest index. Strong correlations have been established between seed size and cooking time especially in kabuli and therefore, special emphasis may be given for improving the seed size with less cooking time in extra-large seeded kabuli chickpea. Further, there is sufficient genetic variability recorded for leaf area index, number of branches per plant, number of pods per plant, plant height, harvest index, seed yield, 100 seed weight, hydration capacity, swelling capacity, cooking time and iron content in the genotypes and the traits exhibited high heritability and high to moderate genetic advance in all three dates of planting.

A breeding effort was carried to investigate genetic variability, heritability, predicted genetic advance and the association studies between seed yield, yield attributing traits and quality traits during Rabi 2022-2023 at ZARS, Kalaburagi, India. The study was taken up with 14 genotypes, which includes advanced breeding lines and released variety as checks were planted in three replications using randomized complete block design. Studies on genetic variability have shown that every character was unaffected by the environment to the same extent. The genotypic coefficient of variation was slightly lower than the phenotypic coefficient of variation indicating that the existing variation is not only by the genotypes but also to some extent by the environment. For the majority of the traits, high to moderate genetic advance was found in conjunction with high heritability. This indicates presence of additive gene action. Hence, breeders can exploit these traits through phenotypic selection. The number of branches and pods on a plant were two key traits that showed a significant association with seed yield whereas, swelling capacity, hydration capacity and cooking time are positively associated with 100 seed weight. Thus, breeders can exploit those traits influenced by additive gene action for further genetic improvement in chickpea and it is possible to develop chickpea genotypes with high yielding and less cooking time. Finally, this investigation should be repeated over years and locations to confirm future breeding program.
