Abstract

Correlation studies conducted in 23 hybrids of tomato (Lycopersicon esculentum Mill.) revealed
that fruit weight, pericarp thickness, acidity, ascorbic acid and lycopene were positively and significantly
associated with yield per plant, while number of fruits per plant was associated negatively. On the
other hand, path analysis studies exhibited that fruit weight had the highest positive direct effect on
yield per plant, while, fruit weight was also having high positive indirect effect on yield per plant.
Therefore, these characters could be reliably looked for, while selecting a high yielding genotype
