Study the Genetic Parameters in Phaseolus
The experiment was conducted at vegetable research farm, horticulture and landscape design, college of
agriculture and forestry, Mosul University, Iraq, during spring season 2018. The aim of this study was to determine of
genetic parameters and correlation coefficients and heritability in 8 genotypes of common bean, genotypes were sown in a
randomized complete block design with three replications. Result showed that significant difference between genotypic in all
the 16 parameters. Genotype BRS Pitango is the best in most the traits, while genotype G11867 is best in the 100-seeds
weight. The Б2 phenotypic and genotypic were higher in plant height, leave area, seeds weight /plot. The heritability in broad
sense and genetic advance were higher in plant height, seed weight /plot and total dry seeds (t/ha.). The results recorded
higher positive significant genotypic and phenotypic correlation coefficients between total dry seeds yield (t/ha.) with the
plant height, seeds weight /plot, seed diameter and 100- seeds weight.
