Fontes de resistência em acessos de Solanum (secção Lycopersicon) a Verticillium dahliae raças 1 e 2

Abstract: A murcha-de-verticílio (Verticillium dahliae) é uma das doenças mais severas do tomateiro (Solanum lycopersicum L.). Duas raças fisiológicas de V. dahliae foram caracterizadas infectando o tomateiro e ambas estão presentes no Brasil. A estratégia de controle mais efetiva para isolados da raça 1 tem sido a utilização de cultivares resistentes em associação com práticas culturais. Entretanto, não existem cultivares comerciais de tomate resistentes à raça 2 do patógeno. Neste contexto, torna-se importante a ident… Show more

“…Despite its prominence, several factors can limit tomato production, such as adverse weather conditions, pests and diseases (VENEMA et al, 2008;MIRANDA et al, 2010;CARRER FILHO et al, 2015). To overcome some of these hurdles, farmers rely on grafting technique, which consists in bonding parts of two plants by means of tissue regeneration developing a single plant (PEIL, 2003;CARDOSO et al, 2006;LOOS;CALIMAN;SILVA, 2009;SIRTOLI et al, 2011).…”

“…lycopersici (CARRER FILHO et al, 2015). Another is Solanum habrochaites, which is adapted to a wide range of latitudes, enhancing tomato growth, even under unfavorable conditions, throughout the cycle if compared to ungrafted plants (VENEMA et al, 2008), as well as providing resistance to Verticillium dahlia, strains 1 and 2 (MIRANDA et al, 2010).…”

“…The predominance of tomato accessions resistant to V. dahliae in S. lycopersicum has been already reported by several authors (Acciarri et al 2007, Miranda et al 2010, due to the constant incorporation of the resistance Ve-1 gene in commercial lines of different breeding programs.…”

“…Although the expression of resistance to V. dahliae is considered dominant, incomplete or partial resistance has been reported in tomato, mainly due to germplasm allelic diversity (Miranda et al 2010), as well as the co-evolution of race 1 with varieties that express resistance to the corresponding physiological race. The widespread use of the genetic factor (Ve gene), that prevailed for decades in the fields of tomato-producing regions, contributed to the emergence of V. dahliae race 1 strains that can infect cultivars containing the Ve gene.…”
