The article presents the results of determining the characteristics of inheritance of traits that determine productivity by F1 hybrids. It was shown that the manifestation of heterosis in early and overall productivity is due to the nature of the inheritance of the number of fruits and their average weight, which changed from positive dominance to negative superdominance depending on the crossing components. Hybrid combinations F1 were distinguished: - L 111 x L 11069: L111 x MaKrista: 111 x L 1185: L 1185 x MaKrista; Zagadka x Facel; L111 x L135; L 111 x Facel, with a high heterotic effect for a number of valuable breeding traits capable to realize genetic productivity potential in the adverse environmental conditions. They can be recommended for outdoor cultivation in Moldova.
