Resumo
The main objective of this study was to test levels of resistance of commercial varieties, genotypes belonging to the germoplasm bank of CNPH-Embrapa and hibrids F1 of tomat to Alternaia solani, in field condition. The trials were conduced at the experimental fields of the Federal University of Goiás, Goiânia-GO, Brasil. It is located at an altitude of 730 m, latitude of 16° 41'S and longitude of 49° 17'W. The evaluations were accomplished at the 36, 43, 50, 57, 64, 71, 78 and 85 days after the seedlings planting, combining diagramatic scale and grades. Among indeterminate cultivars Ohio 4013 and CNPH 738 were the most resistants. Among determined ones the most resistant were F1 hibrid Hawaii 7998 x Monense and Rotam 4. The genotypes Ohio 4013 and the F1 Hawaii 7998 x Monense hibrid were the ones that more stood out for resistance to these pathogen and could be suitable for future breeding programs.
