Resistance of 59 barley cultivars to three distinct isolates of Bipolaris sorokiniana, causing brown leaf spot was tested on seedlings and adult plants in a screen house and in a growth room, by determination of disease incidence, disease severity, and rate of lesion expansion. The disease reaction and severity at the seedling stage differed among cultivars. The cultivars MNS Brite, NDB 112, Kindred, Parkland, and Oderbrucke were moderately resistant to brown leaf spot, but the resistance was partial to all three isolates. None genotype with complete resistance was found. The cultivars CI 9539, Svanhals, and Chevron, considered as sources of resistance, were classified as moderately susceptible, and susceptible, respectively. Disease severity, disease reaction, and incidence of B. sorokiniana in grains also differed among the cultivars at the adult plant stage. Nevertheless, none of the genotypes was resistant to B. sorokiniana. The rate of lesion expansion differed among cultivars BR 2, MN 698, Kitchin, Svanhals, and NDB 112, with NDB 112 having the slowest expansion rate (0.194–0.205 mm2/day). 相似文献

In Southern Brazil, under ideal conditions Soilborne Wheat Mosaic Virus (SBWMV) induces yield reductions to the wheat crop
of over 50%. The only effective way of controlling the disease is through resistance. However, the inheritance of resistance
is not been fully understood. The purpose of this work was to study the genetic control of resistance to SBWMV. Crosses were
carried out between the resistant wheat cultivar Embrapa 16 and the susceptible cultivars BR 23 and IAC 5-Maringá, at the
National Wheat Research Centre, Passo Fundo, RS, Brazil. The parents, F1, F2, and backcrosses were sown in plots in a field where soil was naturally infested with the vector of the virus, the fungus
Polymyxa graminis, in order to promote natural infection. All plants were individually evaluated for severity and type of lesions, according
to a scale of 0 to 5, where, 0 = absence of symptoms and 5 = plants severely affected by mosaic plus dwarfing and rosetting.
The statistical analyses of the data showed broad sense heritability values between 43% and 55%. The data suggested the presence
of two genes controlling resistance to SBWMV in the segregating population of both crosses.
