Genetic analysis for various traits of Cicer arietinum under different spacing

Prescribed study was conducted in Faculty of Agriculture, Lasbela University of Agriculture, Water and Marine Sciences Uthal, Pakistan during crop sowing season of 2013-14. Three varieties were sown in triplicate completely randomized block design using 2 factor factorial analyses. It was suggested that higher genotypic variance, genotypic coefficient of variation, heritability and genetic advance indicated that the traits dry biomass, grain yield per plant, pods per plant, 100-seed weight and seeds per pod. Punjab-2008 and Bakhar-2011 performed batter for most of the grain yielding and its contributing traits. Significant genotypic and phenotypic correlations were reported for dry biomass, pods per plant, 100-seed weight, grain yield per plant and seeds per pod. higher positive direct effects of days to flowering, primary branches per plant, plant height and secondary branches per plant were reported for grain yield per plant on chickpea. Heritability, genetic advance, principle component analysis, principle component biplot and path coefficient analysis indicated that these traits may be used for the development of higher grain yielding chickpea genotypes to improve yield of chickpea.
