Twenty one tomato (Lycoperscion Esculentum Mill.) genotypes were evaluated during 2011/2012 to estimate the magnitude of heritability, genetic advances, and to obtain information on association of different characters with fruit yield and among themselves. The experiment was conducted at Mizan-Tepi University trial field using Randomized Complete Block Design (RCBD) with three replications. High genetic advance accompanied by high heritability was observed for plant height, number of fruit clusters per plant and fruits per plant, suggesting that selection for number of fruits per plant, plant height, and number of fruit clusters per plant would be most likely effective in tomato improvement. Number of fruits per plant showed positive and significant correlation with number fruits per cluster (rg = 0.680**, rp = 0.601**) and shape index (rg = 0.595**, rp = 0.544*) at both genotypic and phenotypic levels, indicating the above characters play important role in yield improvement and that they are more useful in selection process
