MOLECULAR MARKING OF TRITICALE GENOTYPES BY THERESISTANCE TO STEM AND LEAF RUST

Abstract

Breeding lines of SP-2wereevaluated for resistance to leaf and stem rust using the phytopathology methods and DNA markers. Molecular-genetic identification of 64 triticale breeding lines on resistance to stem and leaf rustsallowed us to identify triticale lines with a complex of genes Sr2, Sr22, Lr28 and rye translocation 1BL. 1RS / 1AL1RS. Comparison of results with DNA markers and immunological evaluation showed that 9 lines (243/2416, 2301, 2382, 2455, 2273, 2222, 2312, 2232, 2190) have confirmed their high resistance in the infected field conditions.
