Winter and spring triticale varieties included in the State Register of the Republic of Belarus were screened for genes of resistance to brown, stem and yellow rusts. Analysis with markers for resistance genes showed that amplified fragments linked to the resistance genes Lr25 / Pm7, Lr26 / Yr9 / Sr31 / Pm8, Sr2, Yr5 and Yr10 were present in the varieties under investigation. Winter triticale varieties of Belarusian breeding ‘Antos’, ‘Prometey’, ‘Zhytsen’, ‘Mikhas’ and Polish variety ‘Grenado’ were carriers of the resistance genes Lr25 / Pm7. In addition, ‘Grenado’ had the genes Yr5 and Yr10 of resistance to yellow rust. Winter triticale varieties ‘Moderato’ and ‘Dinaro’ and most of spring varieties, except ‘Milkaro’ and ‘Sadko’, showed field resistance to a brown rust population. The distinguished varieties of triticale, carriers of effective genes of resistance to brown, stem and yellow rust pathogens, can serve as sources of these genes to create resistant varieties.
