Tomato (Solanum lycopersicon) is the one of the most essential and consumed vegetable in the world. A change in the climatic conditions provides the way for biotic and abiotic stress in the vegetable crops. Grafting makes the plants to overcome the stress condition and it provides answer for the quest of stress condition and this was practised in tomato, brinjal, watermelon, etc. to overcome the stress situation like drought and salinity and no studies on waterlogging were reported. Hence a study was proposed to screen the compatible grafts of tomato for flooding condition during vegetative stage based on the previous studies at the Department of Crop Physiology, TNAU, Coimbatore. Different Solanaceous flood tolerant rootstocks are Solanum torvum, Solanum sysimbriifolium, Solanum aculeatissimum, LE 828 were grafted with scion, a commercial tomato plant PKM 1. Cleft grafting was practised and graft of Solanum torvum * PKM 1 recorded higher graft success percentage of 96%. Then the grafted plants were transplanted and subjected to flooding stress in the submergence tank and the different parameters recorded after 7 days of flooding were graft success percentage, number of leaves, shoot height, leaf area, total chlorophyll content. Graft LE 828 * PKM 1 showed better performance compared to other grafts in normal irrigated condition while in flooding condition graft Solanum torvum * PKM 1 performed better compared to other grafts of tomato genotypes in flooding. Hence the solanaceous rootstock LE 828 and Solanum torvum can be used as stress tolerant rootstock overcoming the climate change constrain in future.
