. "Improvement of adaptability to stresses belongs to the main tasks of crop breeding. Recent studies showed close relation of genetic mechanisms of resistance to biotic and abiotic stresses with ABA growth regulation system and synthesis of specificproteins. In wheat the selection under barley yellow dwarf virus (BYDV) is an alternative that looks promising in order to select under stress (especially drought stress). The aim of the proposed project is to study the relation between the response toBYDV and tolerance to biotic stresses in barley (drought, low temperatures), which may help to select genotypes combining resistance to BYDV and tolerance to the mentioned stresses. Besides determination of resistance to low temperature and drought alsothe study of ABA system will be used to monitor the differences in the genotype response to stresses. It will be useful with the use of SSR and AFLP analyses in the available set of DH lines to detect genomic regions having impact on effectiveness of"@en . .
