Abstract

‘Goha’ is new strawberry (Fragaria × ananassa Duch.) cultivar, which was released by Highland Agriculture Research Center, RDA, in 2007. In 2003, this cultivar was originated from a cross between ‘Elan’ and ‘Flamengo’ and showed excellent ever-bearing characteristics including continuous flowering habit and high yield under high temperature and long-day condition. It was named ‘Saebong No.1’ after examination of the characteristic and productivity in summer culture from 2005 to 2006. Again, after two regional adaptability tests in 2007, the cultivar name, ‘Goha’ was released on this cultivar. The general characteristics of ‘Goha’ include erect type, middle vigor, round leaf, and long cluster in growth. The fruit shape is long conic and fruit color is dark red. ‘Goha’ had high soluble solids contents, activity, and good hardness. Fruit weight of ‘Goha’ is about 10.4g and the marketable yield was relatively high because of low percentage of abnormal fruit bearing. It is resistant against powdery mildew and fusarium wilt. ‘Goha’ is suitable for summer culture use export because it shows continuous flowering habit, high yield, and fruit quality under high temperature and long-day condition.

‘고하(Goha)’는 2003년 ‘엘란(Elan)’을 모본으로 하고 ‘플라멩고(Flamengo)’를 부본으로 교배하여 고온장일조건에서 화방이 계속 출현되고 높은 수량은 가진 우수한 사계성개체를 선발한 것이다. 딸기의 여름재배 작형에서 2005년 생산력 검정, 2006년 특성검정을 거쳐 ‘새봉 1호’로 계통명을 부여하였고, 2007년 2지역에서의 적응성 시험 거쳐 ‘고하’로 명명하였다. ‘고하’의 주요특성은 초형이 직립형으로 초세가 중정도이고 엽형은 원형이고 화방이 길다. 개화기와 수확기는 ‘플라멩고’보다 늦다. 과형은 장원추형이며, 과색은 진한 붉은색을 나타낸다. ‘고하’는 당도와 산도가 높고, 경도도 우수한 편이다. 수량성은 평균과중이 10.4g의 소과이고 다수성이다. 병해 저항성은 흰가루병, 잿빛곰팡이병, 시들음병에 강하다. ‘고하’는 고온장일조건에서 화아분화되고, 높은 과실품질과 수량성으로 수출용 여름재배에 적합하다.
