Breeding of 'Seeberry' F-1 Hybrid Strawberry

Abstract

'Seeberry' is a short-day F-1 hybrid strawberry for seed propagation, that was released by the Protected Horticulture Experiment Station (RDA, Republic of Korea) in 2013. Inbred lines derived from domestic germplasms and selected varieties were used to develop this cultivar. 'Seeberry' originated from a cross of two inbred lines: a male parent 'Wongyo 3115' with high firmness and a female parent 'Wongyo 3116' with excellent fruit shape and high yield. 'Seeberry' cultivar should be grown with a crown diameter of over 10 mm to reveal its unique characteristics. 'Seeberry' has an upright plant shape with elliptic leaves, 12-15 flowers per cluster, vigorless growth habit, and average flower bud differentiation compared to vegetatively propagated cultivars. Fruits of 'Seeberry' are conical, having light skin color and approximately 15-16 g in average weight. Yield of this cultivar is about 92% lower than that of 'Akihime', but 'Seeberry' has excellent taste, sugar content of 9.7 degrees Bx, acidity of 0.6%, and good texture. With regard to disease and pest resistance, 'Seeberry' is sensitive to powdery mildew, aphids, and the two-spotted spider mite, and is resistant to anthracnose.
