Five hybrids of muskmelon were evaluated for their vegetative and yield
characteristics In addition to their reactIon 10 fusarium will disaese caused by
Fusarium oxysporum f. sp. melonis. Local commercial cultivar susceptible to fusarium wilt was also growing for comparison. The experiments were carried out I~ commercial .fields naturalty i"fested wilh F. o. f. sp. melon;s at Kantar Shark (ismaiiia Governorate) during autumn season 0' 2000/2001 and 200112002 and in a pathogeb free field al EI-Arish (North Sinai Governorate). which showed no previous problems with wilt disease of melon. VasClJlar wilt Is a sort of disease could not easily cootroliing this disease. Growth characters, (Nit yield. disease incidence and severity were reported. Results showed that high disease Incidence and severity were recorded i~Kantara Shark infested soil on the susceptible cultivar Shahd Eldokki and Galia. Vicar and Ideal hybrids. In additiOn they recorded the lowest earty mariletable and tot~1 yield. On Ihe contrary Primal and Regal hybrids recorded low level of fusarium wilt severity and higher ear1y and tOlal fruit yield specially in pathogen free field of Nort Sinai Govemorate.
