Abstract. The research is aimed at studying the economic characteristics of collectible samples of tetraploid rye and identifying sources of valuable characteristics for the creation of new highly productive varieties. The purpose of the study was to identify sources of economically valuable traits from varieties of tetraploid winter rye of various ecological and geographical origin in the conditions of the West Siberian region. Materials and methods of research. The material for the research was 33 collectible varieties of tetraploid winter rye. The standard variety is a short Tetra. The study of rye is conducted according to generally accepted methods. According to the results of a comprehensive study of economically valuable signs of collectible varieties of winter rye, sources of signs of interest for further breeding were identified: winter hardiness at the level of 4.6 points (Tetra korotkaya, Vlada, Sibir 4, Rokot 95, Plamya, Zazerskaya 3, Igumenskaya 78); plant height 132.4–140.0 cm and resistance to lodging 4.5–5.0 points (Tetra korotkaya, Vlada, Sibir 4, Rokot 95, Igumenskaya Hl, Belaya vezha, Iskra, Igumenskaya 78, Druzhina); yield 797.3–803.1 g/m2 (Tetra korotkaya, Vlada); by productive bushiness 4.3 pcs. (Tetra korotkaya); by ear productivity (ear length 13.1–14.3 cm; ear lake 81.5–85.4 %, grain weight from ear 2.64–2.78 g and from plant 8.59–8.89 g) (Tetra korotkaya, Vlada, Polnovesnaya, Plamya, Iskra, Rokot 95, Igumenskaya 78); grain quality (weight of 1000 grains 55.6–55.9 g, grain size 679.3–700.0 g/l, falling number 201.0 s) (Tetra korotkaya, Igumenskaya Hl, Dubinskaya, Iskra). The scientific novelty lies in the study of the collection of tetraploid winter rye and the identification of sources according to the main economically valuable characteristics. The most promising samples according to the complex of characteristics include: Tetra korotkaya, Vlada, Rokot 95, Polnovesnaya, Igumenskaya 78 and Igumenskaya Hl.
