“…Further, our inoculation technique appeared to work well, and differences in oat cultivar resistance to BYDV can be screened using such a field method. Many barley cultivars carry specific resistance genes to BYDV (Jedlinski 1984), but in oat cultivars the resistance is mainly non-specific (Comeau 1984). However, several oat cultivars with high level of resistance have been released (e.g.…”

Abstract. The effects of barley yellow dwarf virus on the development, grain yield and yield components of oat cultivar Veli and breeding lines Hankkija 78152 and 78033 were studied in two years. Cultivar differences to BYDV infection were best observed at a low infection level. Single tilleranalysis indicated close correlation between symptom severity and reduction in main yield components. Early infection caused greatest yield losses in all cultivars. BYDV strongly reduced both plant height and harvest index. Mild infection reduced the grain yield by 2-B %, but severe infection by 36-41°/o. The number of grains and panicle weight were strongly reduced, but the 1000-grain weight was only slightly affected after severe BYDVinfection. Implications of these results for disease control are discussed.

“…In North America, six strains of BYDV have been identified based on differential transmission by each of five different aphid species (GILL, 1969;ROCHOW, 1969). There is also variation in host tolerance to these strains (COMEAU & DUBUC, 1978 , 1978) and in wild oats (COMEAU, 1984;RINES et al, 1980). ENDO & BROWN (I 964) found tolerance in oats to BYDV to be heritable and relatively easy to identify in segregating populations.…”

“…A. atlantica and A. damascena have genes responsible for high glucan content (Welch et al, 2000). The species A. barbata Pott is resistant to powdery mildew (Thomas, 1992), stem and crown rust (Marshall and Myers, 1961;Carson, 2009Carson, , 2010, BYDV (Comeau, 1984), and it additionally have the highest content of oleic acid (Ladizinsky, 1988;Loskutov, 2005). A. canariensis carries resistance genes to crown and stem rust (Loskutov, 2005).…”

The search for agronomic traits and the use of new sources of variability in oat farming is very important in terms of breeding. Wild species of Avena are grouped into three gene pools depending on their interfertility with cultivated hexaploid oat. The primary and tertiary gene pools are extensive and diverse, the secondary gene pool is relatively small and poorly represented in ex situ gene banks. Appropriate wild species are a valuable source of many appropriate traits such as: high protein, oil, ß-glucan and balanced amino acids composition contents in grain; short culm; cold and drought tolerance. Moreover, they are a source of resistance genes for oat diseases, such as: powdery mildew, crown and stem rust, smuts or barley yellow dwarf virus (BYDV). Note, however transfer of genes from wild to cultivated species is a long and laborious process. These types of methods are used in the species Avena with various end effects. The purpose of this article is to collect information on attempts of transferring different genes from wild oat species to cultivated oats.
