Forty-nine bread wheat genotypes were evaluated in simple lattice design at Jamma and Geregera to determine the extent of variation and association among 11 traits. Analysis of variance showed significant differences (<em>p </em>< 0.01) among the genotypes for all traits, indicating the presence of adequate variability. Maximum values of genotypic coefficients of variation were recorded for spike length (8.66 %), number of productive tillers (8.4 %), number of grains per spike (6.4 %) and thousand-seed mass (6.15 %); this also shows the presence of substantial variability for these traits. Genetic parameters of the study revealed that days to heading, plant height, spike length, number of grains per spike and thousand-seed mass had moderate to high heritability and genetic advance as percent of the mean.
