The resistance to leaf rust (Puccinia triticina), yellow rust (Puccinia striiformis f. sp. tritici) and powdery mildew (Blumeria graminis f. sp. tritici) of the triticale hybrids was evaluated. The material under study consisted of 11 hybrids built up by crossing x Triticosecale Wittmack with Aegilops sp. and Agrotriticum sp. and 9 forms as parental components (5 triticale forms, 2 Aegilops sp. and 2 Agrotriticum sp.) as well as 2 standard and 2 check cultivars. Studies were carried out using the method of artificial inoculation at seedling stage in a greenhouse and at the adult plant stage under field conditions. Plants from each of the above-mentioned forms were inoculated a in greenhouse with four pathotypes Puccinia recondita triticina and Puccinia striiformis f. sp. tritici and population of Blumeria graminis f. sp. tritici, while in the field conditions with a mixture of pathogen cultures. Five tested hybrids showed very high resistance to Puccinia triticina at the seedling and adult plant stages. A high resistance to Puccinia striiformis f. sp. tritici was found among studied forms in both growth stages. Almost all tested forms were affected by population of Blumeria graminis f. sp. tritici at seedling stage except of Aegilops crassa 4x Boiss and Aegilops juvenalis 6x (Thell.) Eig. The parental forms and standard cultivars displayed various responses with respect to rusts and powdery mildew resistance.
