“…Furthermore; plant height, primary and secondary branches per plant and pods per plant were also positively associated with each other and these traits add towards higher biomass".

The present investigation was carried out at Chamelty Agriculture Farm of M.S. Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, Bajhol, Solan, Himachal Pradesh (H.P.) to examine the quantitative traits of chickpea germplasm and their relationship to seed yield. Seed yield per plant exhibited positive and highly significant correlations with biological yield per plant, harvest index, number of seeds per pod and number of pods per plant. The positive non- significant correlations of seed yield per plant were found with plant height (cm), primary branches per plant, 100-seed weight (g), days to 50 per cent flowering, days to flower initiation and days to maturity. These characters emerged as most important factors in influencing seed yield in chickpea.

“…Higher values of variances in plant height, 100‐grain weight, and the number of pods per plant were also reported by previous studies in chickpea accessions. This indicates the importance of these traits in increasing plant productivity (Archak et al, 2016; Khan et al, 2006; Malik et al, 2014).…”

“…Upadhyaya et al (2006) developed a chickpea core collection consisting of 1956 accessions to increase the utilization of chickpea genetic resources in breeding programs, representing 84% and 100% of the variation range of the entire collection in plant height, 100-grain weight, numbers of pods per plant, days to maturity, and grain yield. Working on 13 chickpea accessions, Khan et al (2006) reported that although the genotypic coefficient of variation was relatively low for days to flowering, days to maturity, plant height, and the number of pods per plant, it was high for 100-grain weight.…”

A chickpea (Cicer arietinum L.) collection consisting of 445 Kabuli-type collected from different locations of Iran was evaluated based on six qualitative and 14 quantitative morphological descriptors. Chickpea accessions were widely varied in plant height, the number of pods per plant, plant dry weight, 100-grain weight, grain yield, and harvest index. Grain yield was positively correlated with the number of pods per plant (r = 0.39 ** ), pod fertility percentage (r = 0.42 ** ), dry weight per plant (r = 0.88 ** ), and harvest index (r = 0.30 ** ). The highest value for the Shannon-Weaver diversity index was observed in growth habit (0.98) and leaf color (0.88). The first and second components of the principal component analysis (PCA) explained 17.97% and 16.20% of the total variations, respectively. The cluster analysis results revealed that the accessions with higher pod, leaflet, and peduncle length were grouped in cluster I, whereas cluster II indicated the dominant contribution for the number of pods per plant, plant dry weight, and grain yield. The highest phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for grain yield per plant (44.3% and 48.3%), the number of pods per plant (44.3% and 45.1%), and dry weight per plant (44.4% and 44.8%). The heritability estimates were also more significant for the number of pods per plant, plant dry weight, and harvest index. These accessions might be used in the chickpea breeding programs to expand high-yielding Kabuli-type cultivars with a broad genetic base.

“…By fixing atmospheric nitrogen and enhancing soil structure, chickpeas preserve soil fertility and are crucial to rainfed agriculture. Improving the physical, chemical, and biological characteristics of soils is thought to produce an outstanding crop for environmental agricultural diversification and, as a result, variable agriculture [6]. Up to 141 kg (about 310.85 lb) of nitrogen can be fixed by a healthy chickpea crop per hectare.…”

Twenty-one chickpea genotypes were examined, and an experiment was carried out by using a Randomized Block Design with three replications at the Department of Genetics and Plant breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Naini Allahabad, U.P during the rabi season of 2021-2022. The analysis of variance revealed significant differences existed for most of the traits. Among all the genotypes IPC-05-62 recorded high seed yield per plant followed by IPC-6006, ICCY-10, IPC-05-24, GNG-1958, IPC04-52, KPG-59, IPC-06-77, GNG-1581, JG-24, IPC-97-29, IPC-2K-25, JGM-7 and ESCJ-627U. All these genotypes recorded high seed yield as compared to check UDAY. JG-24 was shown drought tolerant compared to among all genotypes. High Genotypic Coefficient of Variation and Phenotypic Coefficient of Variation was observed for seed vigour and drought tolerance score. High heritability coupled with high genetic advance as percent of mean was observed for plant height, number of primary branches, number of pods per plant, number of seeds per plant, harvest index, seed vigour and drought tolerance score. The correlation studies revealed that seed yield per plant was positively and significantly correlated with plant height, days to 50% flowering, number of primary branches, harvest index and seed index. The path analysis indicated that harvest index was observed as the maximum positive direct effect on seed yield per plant and thus, may be considered as useful traits for yield improvement of chickpea.
