Abstract
The aim of the study was to transfer mlo gene, which determines very effective resistance to powdery mildew (Blumeria graminis DC. f. sp. hordei) from spring barley to winter forms and to determine agronomic value of selected breeding lines under field conditions. The spring barley cultivar Danuta was used as a donor of mlo gene. Mlo gene was introduced into genome of the two multi-row winter cultivars Carola and Bażant, with good agronomic value but susceptible to powdery mildew. Powdery mildew resistance was evaluated under field conditions and natural infection in several homogenous lines with Mlo resistance type, which were selected from generated F1, F1BC1, F2BC1 populations. The homogenous line BKH 5735 resistance to B. graminis f. sp. hordei determined by mlo gene was selected as a result of evaluations under controlled conditions, natural infection and using molecular markers. This line showed good economic value comparable to the control varieties and it may be concluded that the line BKH 5735 has Mlo resistance and provides high-yielding.
