Genetic Variability, Character Association and Genetic Divergence in Barley (Hordeum vulgare L.) Genotypes Grown at Horo District, Western Ethiopia
Journal Title: STAR Journal - Year 2015, Vol 4, Issue 2
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 (P<0.05) differences for 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 nce as percent of the mean, 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 associations of Grain yield with yield 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.
