Many fungal diseases in the world and in the country have been reported on tomatoes and one of the most important diseases is stem cell sclerotia with factor Sclerotinia sclerotiorum is. The damage to the disease varied from zero to 100 percent. This fungus infects a wide range of host plants that are non-agronomic. Due to the production of honey (sclerotia) for several years in the soil and plant remains 200 and more than the contaminated are durable. Control of the disease through agronomy is not so consistent and on the other hand, the chemical struggle with the disease is both difficult and may be cost-effective Therefore, the use of resistant cultivars was the most important and most cost-effective way to control the disease in contaminated areas of tomato cultivars under greenhouse conditions and experimental pots. The cultivars planted are 12. This research was based on a randomized complete block design with the use of millet-worn millet-fungus-induced disease in the six-leaf stage. The results obtained after two weeks of Vernal f1 showed that cultivars had a significant difference at 1% level. Among the cultivars tested, two varieties were Cindel 1 and Tessera f1 as two semi-susceptible cultivars and two cultivars of Savarona had the highest tolerance And three cultivars 2/33 with the Platera disease index .
