Creation of leaf rust resistant varieties is one of the main aims of breeding of this crop. 94 lines of triticale were screened on the presence of genes Lr10, Lr25, Lr26 and its combinations. Lr26 gene was identified in all samples, 3 lines are carriers of Lr10 gene and presence of Lr25 was established in 4 lines. Combination Lr10+Lr26 was identified in lines 13-15т2-6, 13-15т2-7, 13-99т5-7 and 10-205т3-31, combination Lr25+Lr26 was established in lines 13-159т1-17, 12-80т14-1, 12-т1т-5 and 12-80т14-10. Eighty-five lines are resistant to leaf rust and nine lines are susceptible. In four lines resistance to leaf rust is controlled by Lr25 gene, in other lines it may be controlled by other gene (-s).
