Conteúdo: | In cultivated lettuce germplasm, the highest levels of resistance to tospoviruses were identified in the accession ?PI 342444? (= cultivar ?Tinto?). We carried out controlled inoculation assays aiming to characterize the phenotypic expression and verify the spectrum of ?PI 342444?-mediated resistance against a panel of isolates of two tospovirus species: Tomato spotted wilt virus (TSWV) and Groundnut ringspot virus (GRSV). Lettuce seedlings were mechanically inoculated with seven isolates (three TSWV and four GRSV). Plants of ?PI 342444? did not exhibit symptoms after inoculation with TSWVisolates, whereas severe symptoms were observed on the susceptible lettuce control (cultivar ?Vanda?).
