Studies on Genetic Variability and Interrelationship among the Different Traits in Tomato (Lycopersicon esculentum Mill.)

2 Abstract: The genetic parameters, character association and path coefficient analysis between yield and yield contributing characters of different tomato genotypes were studied. The genotypes exhibited a wide range of variability for all the traits studied. The traits were also found to be highly heritable. High genetic advance as percentage of mean was exhibited for fruit weight/plant followed by number of fruits in three cluster/plant and number of flowers in three clusters/plant. Fruit yield had high positive r and r with total number of fruits at pg harvesting period and number of fruits in three clusters/plant. Plant height at flowering, number of flowers in three clusters/plant, days to flowering and total number of fruits at harvesting period also contributed yield directly. The results indicate that for increasing yield, selection should be based on plants bearing more fruits of larger size and weight.
