Abstract

Assessing the level of genetic diversity of collected germplasms enable breeders to exploit existed genetic resources for further breeding programs. Therefore, one hundred thirty-eight Barley (Hordeum Vulgare (L.)) accessions and three standard checks were evaluated using augmented design in the 2019 main cropping season. The accessions were planted in un-replicated plots and the three standard checks were replicated once in each block. The PCA showed that the first two principal components contributed 67.68% of the total variations observed among the genotypes. Principal component one (PC1) alone had contributed 43.02% of the total variations mainly due to tillers per plant, spike length and thousand seed weight in their respective order. Principal component two (PC2) contributed 24.66% of the total variations mainly through days to 50% flowering, days to 90% maturity, and thousand seed weight in their descending order. Genotypes were grouped into four clusters where 51.3%, 33.3%, 14.0%, 0.7% and 0.7% of genotypes fall in cluster I, II, III, and IV, respectively. The result revealed the existence of significant agro-morphological variations among the genotypes included in the study. Based on the characters considered and populations evaluated, the marked diversity observed among the barley genotypes in Ethiopia could be utilized in future crop improvement for various agronomically important traits. Generally, the study revealed the existence of wide range of diversity among barley accessions which has paramount importance for further exploitation of the important traits.
