Estimation of Variability and correlation analysis for quantitative traits in chickpea (Cicer arietinum L.)

Abstract

A study was carried out in the fields of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad, Pakistan during 2010-2011. Twenty elite genotypes including three standard varieties of chickpea were evaluated for means and components of variability, heritability (h2bs), genetic advance and interrelationships for various parameters. Correlation studies showed that Genotypic and phenotypic correlations of grain yield per plant with number of secondary branches per plant, biomass per plant, number of pods per plant and number of grains per plant was positive and highly significant. Genotypic correlation of grain yield per plant with plant height was positive and significant. Genotypic and phenotypic correlations of grain yield per plant with number of days taken to maturity were negative and highly significant.
