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.
