ABSTRACT
Evaluation of F2 population of the cross IIHR-2201 X C-13-1-2-1 was carried out at experimental block, Department of Vegetable Science, College of Horticulture, UHS Campus, GKVK, Bengaluru during 2015-2016. Correlation study revealed that the parameters viz., plant height, number of branches per plant, number of fruits, average fruit weight, fruit length and fruit width have strong association with yield. Therefore, to increase the yield in tomato selection for above mentioned traits can be carried out. path analysis revealed that the number of fruits per plant followed by plant height, average fruit weight, number of branches per plant, pericarp thickness, fruit length, number of locules per fruit and ascorbic acid were showing direct positive effect on yield per plant while other parameters like fruit width followed by fruit firmness, total soluble solids, days to first anthesis and pH were showing direct negative effect. The characters showing high direct effect on yield per plant indicated that direct selection for these traits might be effective and there is a possibility of improving yield per plant through selection based on these characters.
Key words: Tomato, Correlation, Path co-efficient analysis, Direct effect, Fruit yield
