Abstract: The experiment aimed to assess grafting effects on the tomato fruit quality in root-knot nematode-infested conditions in polytunnel cultivation. Three screened resistant brinjal rootstocks against nematode were used as rootstock for tomato grafting with three different scions viz. Hisar Arun, Arka Rakshak and Pusa Rohini. Different biochemical parameters were evaluated using the ripened fruits of tomato and the grafted plants had significantly increased T.S.S. content by 9.84 to 13.5 % and ascorbic acid content by 6.03 to 23.2 %. In contrast, the acidity of tomatoes decreased by 8.6 to 18.8 % as compared to non-grafted tomato plants. Among all treatments, R19 and R20 rootstocks grafted with Arka Rakshak performed best for fruit quality characters.
