“…Moderate PCV and GCV were recorded for plant height, number of primary branches, number of secondary branches, number of pods per plant, Number of seeds per plant, biological yield, seed index, harvest index and seed yield per plant indicating that there is great scope for selection of this character (Table 3). Results were in accordance with the findings of Jeena et al [5], Thakur and Sirohi et al [6], Kishore et al [7], Tsehaye et al [8] and Shivashish et al [9] in chickpea.…”

The present investigation was undertaken with 21 genotypes of Chickpea, (including one check) during Rabi 2020-21 in a randomized block design with three replications at field experimentation centre of Department of Genetics and Plant Breeding. Sam Higginbottom University of Agriculture, Technology and Sciences. The data were recorded for 13 characters to study genetic variability, correlation and path analysis. Analysis of variance among 21 genotypes showed highly significant differences for all the characters indicated the presence of substantial amount of genetic variability. On the basis of mean performance, the highest seed yield was observed in genotype NBEG-1121 and RVS-5949. The estimates of GCV and PCV were moderate for plant height, number of primary branches. Low GCV and PCV was recorded for days to 50% flowering. The difference between PCV and GCV was very low for all 13 yield contributing characters. This indicates that the influence of environment factor was low on these characters. High heritability estimate was recorded for number of seeds per plant, number of secondary branches per plant. A high magnitude of genetic advance expressed as a percent of mean was observed in respect of number of seeds per plant, number of secondary branches per plant. Seed yield per plant exhibited positive and highly significant correlations with days to 50% Flowering, no of secondary branches at both genotypic and phenotypic level. The positive non-significant correlations of seed yield per plant were found with number of secondary branches and days to maturity. Negative non- significant correlation was being observed with the plant height, number of primary branches per plant and number of pods per plant. Path analysis at both genotypic and phenotypic level showed positive direct effects by days to 50% flowering, number of secondary branches per plant. The characters identified above as important components merit due to consideration in the formulation of effective selection strategy in chickpea for developing high yielding varieties.

“…Genetic variation among individuals of a species is highly useful for breeders to identify and select the most desirable genotypes for the breeding programs (Bulti and Haji, 2019;Tsehaye et al, 2020). Estimation of genetic variation and its exploitation in hybridization programs is highly valuable for a successful crop breeding program (Rafiq et al, 2020).…”

Recently chickpea is being grown in more than 50 countries of the world (Tsehaye et al., 2020). Pakistan ranks 3 rd in chickpea producing countries but far below than world's average chickpea productivity per Abstract | Genetic variation occurring naturally in germplasm is highly valuable resource of alleles that can be deployed for genetic improvement of a species. Screening of available genetic stock for detection of most diverse and high yielding genotypes is a pre requisite for a successful crop breeding program. For this purpose, a research experiment comprising of sixty-eight elite chickpea germplasm genotypes along with two commercial varieties were sown under tri-replicate randomized complete block design during the winter season of 2020-21. D 2 statistics, principle component analysis and cluster analysis were employed to detect the most genetically variable and high yielding chickpea genotypes. D 2 statistics extracted higher values for standard deviation and coefficient of variation indicating that the studied genotypes possess considerable amount of genetic variation in performance of studied different traits. Principle component analysis distinguished the traits into eight components. Results revealed that PC1 and 2 extracted >1 Eigen values explaining that these components have major contribution in genetic variability. Cluster analysis distributed the genotypes into four distinguished clusters. Agglomerative dendrogram of genotypes was constructed by Ward's method. On the basis of Euclidean distance it was observed that members of cluster 3 (G.

“…GCV and PCV estimations ranging from high to moderate (10.316, 10.942) reveal that there is a lot of variation across these traits, implying that there is extent for genetic improvement through effective selection. Thakur and Sirohi [15], Shweta and Yadav [16] and Tsehaye et al [17] all observed similar findings. The genotypic coefficient of variation estimations reflect the overall amount of genotypic variability present in the material.…”

During Rabi, 2019-2020, the present trial was carried out at the field experimentation centre of the Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad to assess genetic variability, correlation and path analysis in twenty-six chickpea genotypes, including one check variety Uday for twelve quantitative traits. The analysis of variance revealed significant variations across genotypes for all of the features under investigation, demonstrating a high level of genetic variability in the experimental material. The genotypes C-224, C-201, ICC-16693, C-1028, C-129, C-213, C-130 and C-1025 have been identified as the top performing lines among the genotypes studied. PCV values were found to be higher than GCV for all of the traits investigated, indicating that environmental variables influence the characters. The fact that biological yield per plant has a high PCV and GCV implies that there is a lot of genetic variability in the material for these qualities. Plant height, days to 50% flowering, harvest index, biological yield per plant, hundred seed weight, seed yield per plant and number of pods per plant were all found to have high heritability. For the traits of biological yield per plant, seed index, harvest index, number of pods per plant, seed yield per plant and plant height, high heritability was observed along with high genetic advance as percent of mean, indicating that these characters were primarily governed by additive gene effects. As a result of the accumulation of more additive genes, direct selection of these features using a simple selection strategy would be efficient, leading to further development of chickpea genotypes. Number of seeds per plant, number of pods per plant, biological yield per plant, number of primary branches per plant, number of secondary branches per plant and plant height all had positive significant genotypic and phenotypic associations with grain yield per plant. At the phenotypic level, biological yield per plant and number of seeds per plant both had a strong positive direct effect on grain yield per plant and contributed the most to yield per plant.
