Higher attacks by some fungal diseases are observed in triticale in the recent years. Together with yellow and brown rust, powdery mildew and stem rust are main economically important diseases on triticale. The breeding for resistant cultivars is economically the most efficient and environmentally friendly method for disease control. During 2015 – 2016, 43 triticale lines were selected, which had shown resistance to the causative agents of powdery mildew (Blumeri graminis f.sp. tritici = Erysiphe graminis f.sp. tritici) and stem rust Puccinia graminis. f.sp. tritici, and which possessed very good economic parameters. The investigation was carried out in an artificial infection field at Dobrudzha Agricultural Institute. The lines were divided into two groups according to their resistance to the studied pathogens and their productivity. All lines were analyzed for production potential. Triticale lines 102/99-212, 211/05-107, 63/08-89, 218/08-97 and 93/08-87 demonstrated full resistance to the causative agents of powdery mildew and stem rust and possessed productivity exceeding the used standard with over 20 %. Lines 63/08-86, 63/01-293, 63/08-83, 100/08-93, 218/08-81, 100/08-87, 11/07-95, 195/05-120, 113/07-86, 111/07-102, 93/08-89, 63/08-88, 63/08-79, 157т/9-4, 196/06-135, 195/05-148 combined high productivity with full resistance to powdery mildew and good resistance to stem rust.
