Abstract

Twenty five, diverse six row barley genotypes were evaluated on the basis of yield and yield
related characters at Bako Agricultural Research Center, Shambu sub site. The experiment was
laid down in a Randomized Complete Block Design (RCBD) during 2012/13 cropping season.
The results of the analysis of variance (ANOVA) revealed significance (
all of the characters, except number of grain yield per spike. This indicated the existence of
variability and hence the potential for selection and improvement. The highest mean grain yield
performance was recorded from genotype IBPmGP 3, while the lowest mean performance was
recorded from genotype IBYT-HI16. Thousand seed weight, tiller number per plant, grain yield,
harvest index, spike length and number of kernel per spike were found to have high coefficient
of variability, intermediate to high heritability and genetic adva
suggesting that effective and satisfactory selection for practical improvement of these important
traits is possible. Grain yield showed positive and significant correlations with thousand kernel
weight, biomass yield, and harvest index. Positive a
components give an opportunity to simultaneously improve yield and yield contributing
characters. In conclusion, the observed variability within the twenty five six row barely
genotypes in grain yield and other agronomic traits, indicates the potential for further
improvement through directional selection and hybridization
