    EVALUATION OF CHICKPEA (Cicer arietinum L.) GENOTYPES FOR YIELD AND YIELD ATTRIBUTING TRAITS UNDER LATE SOWN CONDITION
    (Birsa Agricultural University, Ranchi, 2023) ALICE BARA; Ravi Kumar
    Chickpea (Cicer arietinum L.) belonging to family Fabaceae, is an important legume crop with significant economic and nutritional benefits. Believed to have originated in the Mediterranean regions, and being cultivated for over 7000 years it is widely grown and consumed all over the world. Despite its importance, chickpea production faces several challenges such as biotic and abiotic stresses, low yield, and poor-quality seeds. These challenges have prompted extensive research efforts to improve the crop’s yield, nutritional value, and resistance to biotic and abiotic stresses. The present investigation was carried out in Rabi 2021-22 at Western Section of Birsa Agricultural University Research Farm, Kanke, Ranchi. Total thirty-nine genotypes of chickpea including five checks (GNG 2299, Pant G 186, BG 372, KPG 59 and Birsa Chana-3) were taken for present investigation under late sown condition. Observations were recorded on ten quantitative and five qualitative traits under this study. Correlation of different traits with yield and among themselves was also studied. Direct and indirect effects of different traits on yield were estimated at both phenotypic and genotypic level in addition to GCV, PCV, Heritability and Genetic advance. Phenotypic variance was higher than genotypic variance for all the traits and similar trend was followed for PCV and GCV. High phenotypic and genotypic variance was found for yield per plot. High PCV and GCV was observed for number of secondary branches per plant and 100-seed weight. High heritability in broad sense was recorded for the trait days to maturity, number of secondary branches per plant, number of seeds per pod and 100-seed weight. High genetic advance as per cent of mean was recorded for the trait number of secondary branches per plant, number of seeds per pod and 100-seed weight. High heritability coupled with high genetic advance as per cent of mean was observed for number of secondary branches per plant, number of seeds per pod and 100-seed weight which suggested that selection of these traits may be effective as heritability is most likely due to additive gene effects. Positive and significant correlation was recorded for plant height, number of primary branches per plant, number of pods per plant and seed yield per plant for yield per plot. Number of primary branches per plant, number of pods per plant, number of seeds per pod and seed yield per plant showed positive direct effects with yield per plot. The qualitative traits viz., growth habit, flower colour, seed size, seed color and seed texture were able to distinguish chickpea genotypes and thus can be used for germplasm characterization in chickpea as per guidelines of DUS test. Based on the results of performance, it was concluded that four genotypes viz., JG 2021-68, BG 4032, IG21 05 and Phule G1216-10-17 were identified as early chickpea genotypes under late sown condition.
