The adequacy of triticale traits was estimated for including in variety ideotype. The correlation between main traits (yield, grain quality, suitability for processing) and other analysed traits was used to find out acceptable traits for ideotype. Modificative and genotypic variabilities were determined. Such traits as grains per spike, grain weight per spike and spike lenght must be included in ideotype to increase grain yield. To improve suitability for processing it is necessary to include plant height and time to maturity in variety ideotype. Correlation is important between protein content in grains and time to maturity as well as grain number and weight, but changes in these traits acceptable for breeder decrease protein content in grains. The most genotypic variable has following traits: plant height, 1000 kernel weight, grain weight per spike. The inclusion of the mentioned traits in the ideotype makes it possible to select valuable genotypes.
