dc.description.abstract Approximately 900 accessions of Avena sterilis and A. fatua, which originated from 15 different countries were challenged with race 5 of Blumeria graminis f.sp. avenae, which causes powdery mildew in oat. Among the F2 progeny, 3 different lines expressed very good adult plant resistance, though each had a degree of seedling susceptibility. The inoculum level in the greenhouse was extremely high, much greater than would be expected under normal field conditions. During an unrelated experiment involving A. strigosa, 2 accessions (from Portugal and Uruguay) were also noted to have some resistance to B. graminis. Of the wild weedy diploid species of oat, 13 have been designated as A genome species. Four, A. longiglumis, A. prostrata [Avena hirtula], A. canariensis and A. damascena have been assigned the genomic designations AlAl, ApAp, AcAc and AdAd, respectively, based on these criteria, while the remaining species have been assigned to the 'strigosa' group with the genome designation of AsAs. The preliminary observations of genetic variation and breeding prospects on the evaluation and enhancement of Avena landrace collections for extensification of the genetic basis of Avena for quality and resistance breeding are presented. en
