The investigations in the Triticale collection, which began in 1981, comprised materials gathered in the working collection. In further years materials from foreign collections and breeders were obtained. Field and laboratory estimation of some important agronomic traits which could be of use in the practical breeding, were performed on these materials. The results of 3-year investigations /1982-1984/ of such traits, as weight of grains per ear, 1000 grain weight and protein content, are discussed. There is a wide variability range of the traits under study, the calculated variability coefficients being for the protein content V = 12,2%, for 1000 grain weight V = 14,2%, for weight of grains per ear V = 28,0%. A negative correlation between the protein content on the one hand and the 1000 grain weight and the weight of grains per ear of the other has been proved. There is a significant interrelation for the pair of traits: 1000 grain weight - weight of grains per ear.
