MARKING OF RESISTANCE GENES TO LEAF RUST AND THEIR ExPRESSION AT DIFFERENT STAGES OF ONTOGENESIS IN WINTER TRITICALE VARIETIES AND SAMPLES

Abstract

The laboratory evaluation of resistance of 49 samples of winter triticale to agent clones of leaf rust has been carried out. It’s established that in the winter triticale variety Moderato and samples 13/14, 23/14, 24/14, 77/14, 81/14 translocation 1RS.1BL is identified with resistance genes Lr26/Yr9/Sr31. It is shown that winter triticale samples 114/14, 115/14 is resistant to leaf rust at different stages of ontogenesis. Samples 10/14, 79/14, 102/14, 103/14, 108/14, 109/14, 116/14 of Moderato and Dinaro varieties also have fielding resistance.
