dc.descriptionThe purpose of the present study was to estimate the heritability of traits through phenotypic, genetic and environmental parameters related to the production components and agro-morphological characters: plant height (PHt), days to heading, lodging, grain yield (YLD), thousand kernels weight (TKW), protein content, and commercial classification of grains (CLASS) of an elite collection of 39 barley genotypes grown under irrigated conditions in the savannah of Central Brazil. The experiment was planted under irrigation on May 2009 at Embrapa Cerrados, Federal District, Brazil. A complete randomized block design with four replicates was used. Genetic variability was observed among the tested genotypes. The genotypic correlations (in absolute values) found for all traits were greater than their corresponding phenotypic and environmental correlations. A significant influence of genetic factors on trait expression was observed. It could be concluded that the phenotypic expression is decreased depending on the environmental conditions. The greatest magnitudes for the genotypic and phenotypic correlations were found for TKW and CLASS. Trait YLD was positively correlated to PHt in terms of genotypic and phenotypic correlation. The selection accuracy was rated high for all traits. The high magnitudes found in the estimation of broad sense heritability indicated the existence of genetic variability, showing the possibility of obtaining genetic gains through the selection for all characters.pt_BR
