In the conditions of the Republic of Belarus there was created a new breeding material by means of intraspecific hybridization, as well as there were studied peculiar features of inheritance of the main economic and agronomic traits in hybrid combinations. There were presented results of studying of inheritance of quantitative traits hybrids of winter triticale (Triticosecale) in the system of intraspecific hybridization. The results revealed that the highest F1 values (in accordance with all elements of the efficiency) were marked in the experiment when the winter triticale varieties Mikhas, Ugo and Disko were used as the parent forms. The carried out analysis of inheritance and value of heteroic quantitative signs has shown that in some hybrid combinations ((Disko x Ugo, (by height of a plant, productive bushiness, to number of grains in the main ear, weight of grain from the main ear), Ugo x Disko (on height of a plant, productive bushiness, length of an ear, number of grains in the main ear, weight from a smooth ear)) there were marked positive values true and hypothetical heterosis.
