Abstract

In Ethiopia, tomato is one of the most popular vegetables produced by small farmers and commercial growers for both local uses as well as processing industries. Considering the importance of tomato as one of the beneficial vegetables for both domestic consumption and export markets, it is important to increase its productivity along with desirable attributes through its genetic character. On the basis of its wide use and expansion potential the need for developing varieties that suite specific agro- ecological conditions and specific end use is clear. Thirty-six tomato genotypes were evaluated for yield contributing characters to observe their associations and direct and indirect effect on yield. Character association analysis among yield and yield contributing characters revealed that the genotypic correlation coefficient was higher than the respective phenotypic correlation coefficients in most cases. This indicated that the suppressive effect of the environment modified the phenotypic expression of these characters by reducing phenotypic correlation values. Also, narrow difference between phenotypic and genotypic correlation coefficient was noticed for almost all the pairs of characters studied showing that masking or modifying effects of the environment was little indicating the presence of an inherent association among these characters. Fruit diameter showed significant and positive association with yield/plant at genotypic level but all other characters had non-significant negative and positive association with yield/plant. Path coefficient analysis revealed that fruit shape index had the highest positive direct effects on fruit yield/plant suggesting their importance while imposing selection for correlation of yield in tomato.
