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 $9.7^{\circ}Bx$, 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.

'씨베리' 품종은 농촌진흥청 국립원예특작과학원 시설원예시험장에서 2013년도 육성한 국내 최초의 일계성 딸기 $F_1$ 품종이다. '씨베리' 품종을 육성하기 위해 2004년부터 국내 보유 유전자원 중 특성이 우수한 품종들을 선발하여 약 10여 년에 걸쳐 주요 형질별로 근교계통을 육성하였다. 이중 고경도의 특성을 가진 근교계통인 '원교3115호'를 교배모본으로 하고 수량성과 과형이 우수한 근교계통인 '원교3116호'를 화분친으로 하여 $F_1$ 일대잡종 '씨베리' 품종을 육성하였다. '씨베리' 품종을 종자로 재배하기 위해서는 관부 직경이 10mm 이상이 되도록 육묘하고 정식하여야 제 특성을 나타낼 수 있다. '씨베리'의 초형은 직립형이고 잎은 타원형이다. 초세는 영양번식 개체보다는 다소 약한 경향이고 화방당 꽃수는 12-15개, 화아분화는 대조품종과 비교하여 중간 정도의 특성을 나타낸다. '씨베리' 품종의 과실 특성을 보면 과형은 원추형, 과색은 연한 적색이고 평균과중은 15-16g 내외이다. 수량은 대조품종인 '아키히메' 품종의 92% 수준으로 다소 적은 경향이고 당도는 $9.7^{\circ}Bx$, 산도는 0.6%로 맛은 새콤달콤한 경향을 나타낸다. 병해충 저항성은 흰가루병에는 약하나 탄저병에는 강하고 진딧물과 응애는 다소 약한 것으로 나타났다.
