摘要

'BRS Tospodoro' is a high lycopene tomato cultivar, which combines multiple disease resistance genes and desirable processing traits. This cultivar was found to be suitable for both conventional and organic crop systems. 'BRS Tospodoro' was obtained via backcross breeding using 'Viradoro' as recurrent parent and the inbred line 'CNPH 1306' as the donor of the Pto gene (resistance to Pseudomonas syringae pv. tomato race 0). 'BRS Tospodoro' has the Mi1-2 gene that controls resistance to root-knot nematodes (Meloidogyne incognita, M. javanica, and M. arenaria) as well as tolerance to populations of the aphid Macrosiphum euphorbiae (vector of Potyvirus species), and to whiteflies (Bemisia tabaci). 'BRS Tospodoro' has also the Sw-5b gene, which controls resistance to major Tospovirus species (Groundnut ringspotirus, Tomato chlorotic spot virus, Chrysanthemum stem necrosis virus, and Tomato spotted wilt virus). This cultivar is also resistant to Stemphylium solani and S. lycopersici (Sm gene), Fusarium oxysporum f. sp. lycopersici race 1 (I-1 gene) and Verticillium dahlie race 1 (Ve gene). 'BRS Tospodoro' presents uniform fruit ripening, with the first harvest being done around 110 to 120 days after plant emergence. The fruits are firm, square-shaped, with an average weight of 46 g (in organic cropping) to above 70 g (in conventional cropping). The soluble solids content is in the range between 4.6 and 4.8 oBrix. The external fruit color is uniform (gene u) and bright red (L* = 44.1; a* = 33.9; b* = 20.4). The average lycopene content of mature fruits is 104 μg/g. This cultivar has the jointless locus (j2), which facilitates both manual and mechanical harvesting. 'BRS Tospodoro' has determinate growth habit (locus sp) with vigorous foliage, which provides good fruit protection from sunscald. 'BRS Tospodoro' can be cultivated in all the traditional processing tomato-producing areas of Brazil without the need of any technical adjustment. 'BRS Tospodoro' displayed very good adaptation to the South Brazilian Region and South Cone of South America (Argentina and Uruguay), where P. syringae pv. tomato and Tospovirus are serious economic problems for the crop. 'BRS Tospodoro' might also be cultivated in traditional processing tomato-producing areas (South-East, North-East and Central Brazil), if geminivirus control measures are adopted. Due to its vigorous foliage, 'BRS Tospodoro' requires careful monitoring of the environmental conditions that favors late blight (Phytophthora infestans) epidemics. 'BRS Tospodoro' has been evaluated under organic crop systems with excellent performance in field assays conducted in Brasilia-DF, Brazil.
