Breeding of 'Daewang' Strawberry for Forcing Culture with Good Taste and Fragrance

Abstract

Abstract.A new cultivar 'Daewang' strawberry was developed by the National Institute of Horticultural & Herbal Science for forcing culture in 2010. The cultivar 'Daewang' was originated from the cross between 'Maehyang', a high firmness cultivar and 'Wongyo 3111', a high sugar content in 2006. The cultivar shows erect plant type, vigorous growth habit, early flower bud differentiation with 12-15 flowers per cluster from planting on healthy nursery. Fruits of 'Daewang' are conical type having a bright red skin color, and 16-17 g in an average weight. 'Daewang' is suitable for forcing culture as time required for dormancy breaking ranged between 50 and 100 hours. This cultivar has excellent taste for high sugar/acid ratio as sugar content of 11.1 °Brix, acidity of 0.39% with abundant texture and can be harvested by late spring because the fruit firmness of 'Daewang' was 18.2 g･mm -2 that was about 7.9 g･mm -2 higher than 10.3 g･mm -2 of 'Akihime' cultivar. But although total yield is not significantly different from 'Akihime' cultivar, its marketable yield is remarkably higher than that of 'Akihime' cultivar. Disease and pest resistance of 'Daewang' have a tendency to sensitive powdery mildew, anthracnose and spotted spider.

Effectiveness of Different Classes of Fungicides on Botrytis cinerea Causing Gray Mold on Fruit and Vegetables

“…South Korea is the fifth largest producer of strawberries, producing approximately 230,000 tons in 2012, behind the United States, Spain, Turkey, and Egypt (Na et al, 2013). However, many strawberry diseases have become major hindrances to strawberry production and export, including anthracnose crown rot caused by Colletotrichum fructicola , gray mold caused by Botrytis cinerea (teleomorph: Botryotinia fuckeliana ), Fusarium wilt caused by Fusarium oxysporum f. sp.…”

“…경도가 높은 촉성재배용 딸기 '하이베리' 품종 육성 18세기 유럽에서 F. virginiana와 F. chiloensis간 인위적인 종간 교잡에 의해 탄생하였고 (Darrow, 1966;Bringhurst, 1990;Um et al, 2019), 품종육성은 단교잡에 의한 육종 방법이 세계적으로 가장 많이 이용되고 있다 (Na et al, 2013). 2019년 기준 국내 딸기재배 면적은 6,462 ha로 대부분 시설재배 형태로 촉성재배가 주를 이루고 있으며, 전체 생산량은 234,000톤, 생산액 은 1조5,090억 원으로 과채 생산액의 28.9%로 1위를 차지하여 농가 소득의 기여도가 매우 높은 중요 작물이다 (Choi and Jeong, 2020;KOSIS, 2020).…”
