초록

'장하'품종은 농촌진흥청 국립식량과학원 고령지농업연구소에서 2014년도 육성한 사계성 딸기 신품종이다. '장하'는 '고하'품종을 모본으로 하고 '엘시뇨' 품종을 부본으로 2008년 교배하여, 고온장일조건에서 당도가 높고 화방이 연속적으로 출현되는 우수한 사계성 개체를 선발한 것이다. 고랭지의 여름재배 작형에서 2011년 생산력 검정, 2012년 특성검정을 거쳐 '새봉 6호'로 계통명을 부여하고, 2013-2014년에는 2지역 적응성시험을 거쳐 '장하'로 명명하였다. '장하'의 초형은 반개장형이며, 엽형은 타원형이며, 초세가 중간이다. 과실모양은 원추형이며, 과색은 붉은 색이다. 엽수는 21.4매로 '플라멩고'의 55.8매 보다 34.4매 적다. '장하'의 당도는 8.9%로 '플라멩고'의 7.7%보다 1.2% 더 높다. '장하'의 평균과중은 11.7g으로 사계성 품종 중에서 중간크기에 속하는 편이고, 상품수량은 $19,013kg{\cdot}ha^{-1}$으로 '플라멩고' 품종보다 141% 더 많았다. '장하'는 식미가 좋아 생식용으로 적당한 사계성딸기 품종이다.

'Jangha' is a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2014. The 'Jangha' cultivar originated in 2008 from a cross between 'Goha' and 'Elsinore' that showed excellent ever-bearing characteristics, including continuous flowering habit and high soluble-solids contents under long-day and high temperature conditions. This cultivar was initially named 'Saebong No. 6' after examining its characteristics and productivity in summer culture from 2010 to 2012. After two regional adaptability tests in 2013-2014, 'Jangha' was selected from Saebong No. 6 as an elite cultivar. The general characteristics of 'Jangha' include semi-spreading type, elliptical leaves, and moderately vigorous growth. The fruit are conical in shape, and red in color. 'Jangha' plants have 21.4 leaves, 55.8 fewer than 'Flamenco' plants. The soluble-solids content of 'Jangha' was 8.9%, which was 1.2% higher than that of 'Flamenco'. The average fruit weight of 'Jangha' was about 11.7g and the marketable yield was $19,013kg{\cdot}ha^{-1}$, 141% higher than 'Flamenco'. 'Jangha' is suitable for summer season cultivation as a high soluble solids contents cultivar, because it shows continuous flowering habit under long-day and high temperature conditions.
