Avaliação de danos causados pelo Barley yellow dwarf virus: PAV em cultivares de trigo no Brasil

Abstract: Com o objetivo de avaliar os danos causados pelo Barley yellow dwarf virus - PAV (BYDV-PAV), em cinco cultivares de trigo (BRS 177, BRS 179, BRS 194, BRS Camboatá e BRS Angico), foi conduzido um experimento no telado da Embrapa-Trigo (Passo Fundo RS) no ano de 2005. Os danos induzidos pelo BYDV-PAV foram determinados por meio de análise de características agronômicas (estatura das plantas e massa de matéria seca) e do rendimento (número de afilhos, espigas e grãos por planta; massa de mil grãos). Os dados fora… Show more

“…For a specific cultivar, one of these characteristics can be more important than the other (Cao et al 2015). Some Brazilian wheat genotypes have been evaluated for tolerance to R. padi and/or BYDV and for antixenosis and antibiosis to S. avenae (Lanzarini et al 2007;Peruzzo et al 2007;Cezare et al 2011;Savaris et al 2013;Silva et al 2013). Although the methodologies employed in these studies were differ-ent from each other, in general, the cultivar BRS Timbau´va is described as resistant (based on antibiosis and tolerance studies) to R. padi and potentially tolerant to BYDV but, on the other hand, it appears to be sensitive (by antibiosis) to S. avenae.…”

“…In other studies with barley, a reduction was observed in TSW ranging from 3.2 to 14.9% between plants inoculated with BYDV-PAV and healthy plants (Edwards et al, 2001) and, for wheat, the same inoculation resulted in decrease in TSW between 16.9 and 38.4% (Lanzarini et al, 2007). The differences between the present work and other studies, related to results for the variable TSW, are probably due to a higher incidence and severity of YDD found by the authors, since those works were conducted under controlled conditions and high viruliferous aphid population, which drastically affected TSW.…”
