Abstract

                                The present investigation was carried out at three locations, viz., Rayakottai (E1) Oddanchatram (E2) and Attur (E3 ) of TamilNadu during the summer season, 2007. The experimental material consisted of two tomato F1 hybrids, their parents and ToLCV resistant and susceptible check varieties/hybrids. The experiment was laid out in a randomized block design with three replications. The results of pooled mean revealed that the two synthesized hybrids viz., CLN 2123A X HN2 and HN2 X CLN 2123A registered higher plant height, number of branches, total phenol content and yield per plant than their parents. Plant height, number of branches per plant, and number of fruits per plant revealed significantly positive association with fruit yield per plant in all the three locations. Pooled mean value of ToLCV incidence recorded at 60 DAP and 75 DAP exhibited negative and significant correlations with plant height, number of fruits per plant, total phenol content and fruit yield per plant in all the three locations. The quality parameters viz., TSS, titrable acidity and ascorbic acid content exhibited positive but non significant correlation with yield per plant.
