Popis: The modern triticale varieties have high feed advantages, they have a good tolerance to difficult environments and they are resistant to majority of phy-topathogens. For the period of 2005-2006 phytosanitary monitoring for the triticale samples of different ecologo-geographic origin with spring (327 samples) and winter (37 samples) type of development from N.I. Vavilov All-Russian Scientific Research Institute of Plant Growing on the resistance to the basic wheat patho-gens of Northwest region of the Russian Federation (brown and yellow rust, wheat leaf blotch, powdery mildew) was carried out. In addition, the authors deter-mine the duration of interphase periods, the height of plants, the mass of 1000 grains. The pathogen of powdery mildew does not develop on samples of triticale. The maximal number of triticale samples, introduced from the European part of the former Soviet Union (Ukraine, Belarus) was characterized by absence of de-feat symptoms by brown rust and wheat leaf blotch agents. Pathogenesis of the yellow rust agent was not found on the triticale samples, received from Central Asia, Northern Europe, Australia, South America, Asia and Africa. As was revealed, the greatest degree the attribute of triticale origin influenced on wheat leaf blotch pathogenesis, in the least – on brown and yellow rusts pathogenesis. As was revealed, the criterion of a triticale origin influenced on wheat leaf blotch pathogenesis in the greatest degree, and in the least – on brown and yellow rusts. In the greater degree the plants development type affect the wheat leaf blotch pathogenesis on triticale samples of the Russian selection and in smaller - on triticale samples, received from European part of Former USSR, Northern Europe, East Europe, Central Europe. Keywords: triticale, cereal crop diseases, leaf rust, yellow rust, wheat leaf blotch, powdery mildew.
