The article presents the results on the use of lines of carriers of mutant marker genes in crossings to obtain heterotic F1 hybrids. The degree of dominance of the main traits of determining productivity (the duration of the growing season, the average number of flowers on inflorescences, the number of fruits and the mass of the fruit), depending on the characteristics of the initial parental forms, is shown. Combina-tions of hybrids with a high effect of heterosis in all studied features are isolated.
