Fragaria × ananassa (Duch.) cultivars, ‘Wongyo 3115’ and ‘Wongyo 3116’, were bred as an intermediate parent line using heterosis of F1 hybrids in octoploid strawberry. These two new cultivars were developed as inbred lines (S9 generation) propagated from both seed and runners/stolons. ‘Wongyo 3115’, an inbred line derived from the ‘Benihoppe’ cultivar, has a semi-upright plant shape showing a vigorless growth habit, weaker than the original ‘Benihoppe’ cultivar; it has early flower bud differentiation and produces 10 flowers per cluster when grown from healthy seed. ‘Wongyo 3115’ has low yields of conical type fruit with pink colored skin; average fruit weight is approximately 11 g. The important characteristic of ‘Wongyo 3115’ is its excellent fruit firmness, firmer than the original variety. ‘Wongyo 3116’, an inbred line derived from the ‘Doyonoka’ cultivar, has an upright plant shape, vigorless growth habit, weaker than that of the original ‘Doyonoka’ cultivar; it has early flower bud differentiation and produces 8 flowers per cluster when grown from healthy seed. ‘Wongyo 3116’ has oblate type fruits with red skin and an average weight of approximately 12 g. The important characteristics of ‘Wongyo 3116’ are excellent fruit shape and higher yield than other inbred lines, although it produces small fruits compared to the original cultivar. Both cultivars have excellent taste, high sugar/acid ratio, and good texture. In regards to disease and pest resistance, ‘Wongyo 3115’ and ‘Wongyo 3116’ have a tendency to be sensitive to powdery mildew, anthracnose and the two-spotted spider mite.
