Abstract:

Thirty eight genotypes of tomato were evaluated for yield and yield-contributing characters. Various genetic parameters like variability, heritability and genetic advance were calculated. The test genotypes exhibited a wide range of variability for traits under consideration. These traits were also found to be highly heritable. Phenotypic coefficient of variation (PCV) was found to be greater than genotypic coefficient of variation (GCV) for all the characters studied. High heritability was observed for fruit yield plant-1 followed by average fruit weight while number of primary branches plant-1 exhibited lowest heritability results. High heritability combined with high genetic advance was shown by average fruit weight suggesting, additive gene action plays a major role in governing these traits. Thus, these traits are amenable to simple selection for their improvement.
