Ten promising and one respective local check of cassava (Manihot esculenta Crantz) genotypes were tested at Areka, Bele and Goffa districts of southern Ethiopia during 2006-2007 growing seasons using RCBD with three replications. The objectives of the study were to examine the interrelationship of yield related characters and extent of their contribution to fresh root yield on cassava. The genotypic correlation between fresh root yield and number of vertical stem/plant, root girth, root diameter, weight of above ground plant parts and root dry weight was highly significant, while positive and significant phenotypic correlation was observed between root fresh yield plot and root girth, root length and diameter. Among these characters, roots diameter reflected the highest direct effect of (p=1.976) towards root fresh weight; while minimum was indicated by number of branches/plant (p=0.004). Number of vertical stem/plant, stem girth, weight of above ground plant parts and root dry weight had contribute to the root fresh weight. Therefore indirect selection for higher fresh root yield may be effective for improving these characters. This study suggests the relative higher value of residual effect (0.364) indicated more yield components should be considered in the future to account for the variation in cassava root yield.
