The Cuban tomato line LD3 , in which the Ty-1 gene from Solanum chilense LA 1969 was detected, was crossed with an F1 hybrid carrying the genes Ty-3 from S. chilense LA 2779 and Sw-5 from S. peruvianum. A hundred F2 plants were transplanted to a ferralitic soil in the field and the F2 plants individually evaluated in the field with high natural TYLCV-IL (Cu) incidence by using a scale from 0 (no symptom) to 4 (severe stunting). The total DNA extracted from the F2 plants were analyzed per individual plant by using PCR markers linked to the genes Ty-3 (resistance to TYLCV) and Sw-5 (resistance to TSWV) so that both genes could be detected in a same genotype. Eighty two F2 plants showed no symptoms under natural TYLCV incidence (0 symptoms) with a...
