The tomato accessions were found to vary in their resistance to strain 1 and strain 2 of Fusarium oxysporumf sp. Lycopersici .This study shows that some diversity exists in the tomato accessions. Severity test for strain 1 shows that 7 varieties showed mean resistance while NGIANMAY/09/030, Pure wate~ and NG/MRIMAY/09/005 were susceptible. Maximum rating was 3.5 on NG/MRIMAY/09/005 and NGIANMAY/09/030 when challenged with stain 1 on the field. Under field condition, many of the varieties that were grown were severely affected. Almost all varieties were susceptible to strain 2 of the inoculated Fusarium It is well documented that the occurrence of disease in plant was found to depend on at least two components: pathogen and its host plant; and for disease development requires favorable environmental condition. This study showed the different resistant level of the ten accessions to Fusarium wilt disease which is a soil borne disease. NG/MRIMA Y/09/006 exhibited minimum resistance in terms of disease severity, number of leaves and fruit yield, with its yield comparably high, which makes the variety as the best performing accessions used. It was observed from the data taken that all the tomato accessions inoculated with the fungi, fusarium oxysporum fsp .lycopersici shows the symptoms of Fusarium wilt, therefore the best way to control the disease is by planting under irrigation during the dry season
