The data about elements of structure of the crop yield of initial parental forms of triticale and secalotriticum (triticale with rye cytoplasm) and their hybrids is presented. They are obtained after di-allele crossing. Regularity of inheriting signs of productivity of parental forms by F1 hybrids is examined. F1 hybrids crop yield structural elements characteristics are shown. Among them are: tilling capacity; longevity, spikelet number and grain number of the main spike; grain weight of the one plant; 1000 grains mass. The structural analysis shows the hybrids obtained in reciprocal combinations of crossing triticale and secalotriticum, are more productive and have the effect of heterosis in relation to the parental forms. The conclusions made allow using of the hybrid with different genetic composition and nuclear structure in systematic crossing of the species towards productivity increase.
