Abstract:
Among 83 seed samples of tomato, 16 were naturally infected with Fusarium oxysporum, while the percentage of infection ranged from 1 to 22 per cent. Based upon pathogenicity tests and race identification using tomato differential cultivars, two races 1 and 2 of F. oxysporum f.sp. lycopersici were identified. Greenhouse tests of the resistance reaction of 9 tomato cultivars against local isolates of races 1 and 2 of the fungus showed that cultivars Flora Dade, and PomoDoro were resistant to race 1, while cultivars Peto 86 and Super Marmand were resistant to race 2. Only Strain-B was resistant to both races. The other cultivars were susceptible or moderately susceptible to both races of the fungus.
