Genetic Variability, Heritability and Genetic Advance for Yield and Yield Related Traits in Barley (Hordeum vulgare L.) Germplasm

Abstract

Sixty four barley genotypes were tested in 8x8 simple lattice design at Atsbi, Ofla and Quiha environments in Tigray region, in 2009/10. The overall objective was to study the extent of genetic variability, heritability and genetic advance among the said genotypes. Analysis of variance (ANOVA) study revealed that there was a significant difference (p< 0.001) among the genotypes for all the characters studied except for 1000-kernel weight at Quiha which was significant (p<0.05) and plant height was non-significant at Atsbi and Ofla. High phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were recorded for number of productive tillers/m and number of kernels/spike across locations. High GCV along with high 2 heritability and genetic advance was obtained from number of productive tillers/m and number of kernels/spike 2 across locations.
