| The commercial tomato, Lycopersicon esculentum, cultivars Ângela Gigante I-5100 and Santa Clara (tospovirus susceptible), the Stevens cultivar, lines and experimental hybrids (tospovirus resistant), were used: a) to evaluate two sources of resistance to tospoviruses in tomato (one from L. esculentum/Rey de Los Tempranos, and another one from L. peruvianum/Stevens); and b) to verify statistically significant correlation between virus concentration determined through DAS-ELISA and symptomatology. In the Ângela Gigante I-5100 and the Santa Clara cultivars, the correlation coefficient was highly significant and the symptom average level was high, showing that in susceptible cultivars the symptom evolution is related to the virus multiplication in the plant.
