Keywords:
Genetic Variance, chickpea, Heritability, Genetic advance, genotypicAbstract
This study evaluated Genetic variability, heritability & Genetic advance in early development of chickpea. Twenty-five chickpea genotype were utilized in a Completely Randomized Design (CRD) with three replications at The University of the Punjab, Lahore. Morphological data were collected for seven traits length of seedling(SL),Length of root(RL),Root-and-Shoot-ratio(RTSR),Biomass of seedling(SB),Length of leaf(LL),width of Leaf(LW) and Area of leaf(LA) at early stage and analyzed.The Combined analysis of variance (ANOVA) revealed significant difference is high highly (P≤0.01) in all genotypes for all examined traits, underscoring substantial genetic variability within the current chickpea genotypes. Notably, traits such as Leaf-Area, Root-length, Leaf-length, and Leaf-width exhibited elevated heritability and GA, indicating feasibility on the basis of phenotype selection to enhance these traits. This insight provides valuable information for the targeted improvement of chickpea varieties through selective breeding based on these specific phenotypical characteristics.
