Abstract

This work characterizes 'Yeolha', a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar that was released by the Highland Agriculture Research Center, RDA, in 2013. This cultivar originated from a 2008 cross between 'Goha' and 'Elsinyo' and showed excellent ever-bearing characteristics including continuous a flowering habit under long-day and high temperature conditions. It was originally named 'Saebong No. 5' after examining its characteristics and productivity in summer culture from 2010 to 2013. After two regional adaptability tests in 2012, it was selected as an elite cultivar and renamed 'Yeolha'. The general characteristics of 'Yeolha' include a semi-spreading plant type, elliptic leaves, and strong vigor in growth. Its fruit is conical and red. T he s oluble s olids content of 'Yeolha' is 8 .6%, w hich is 0.6% h ig her than t hat of 'Flamenco', b ut f ruit hardness is lower than that of 'Flamenco'. The average fruit weight of 'Yeolha' is about 12.1 g and the marketable yield is $28,133kg{\cdot}ha^{-1}$, which is 117% higher than that of 'Flamenco'. 'Yeolha' is resistant against Fusarium wilt. In addition, 'Yeolha' is suitable for four-season cultivation as a high harvesting cultivar because it shows continuous flowering under long-day and high temperature conditions.

'열하' 품종은 농촌진흥청 국립식량과학원 고령지농업연구센터에서 2013년도 육성한 사계성 딸기 신품종이다. '열하(Yeolha)'는 '고하(Goha)' 품종을 모본으로 하고 '엘시뇨(Elsinyo)' 품종을 부본으로 2008년 교배하여, 고온장일조건에서 과실이 크고, 화방이 연속적으로 출현되는 우수한 사계성 개체를 선발한 것이다. 고랭지의 여름재배 작형에서 2010-2013년 생산력 검정, 특성검정을 거쳐 '새봉 5호'로 계통명을 부여하고, 2012년에는 2지역 적응성시험을 거쳐 '열하'로 명명하였다. '열하'의 초형은 반개장형이며, 엽형은 타원형이며, 초세가 강한 편이다. 과실모양은 원추형이며, 과색은 붉은 색이다. '열하'의 당도는 8.6%로 '플라멩고'의 8.0%보다 0.6% 더 높다. 그러나 경도는 '플라멩고'보다 낮았다. '열하'의 평균과중은 12.1g으로 사계성 품종 중에서 중간크기에 속하는 편이고, 상품수량은 $28,133kg{\cdot}ha^{-1}$으로 '플라멩고' 품종보다 117% 더 많았다. 병해저항성은 시듦병에 저항성이다. '열하'는 고온장일조건에서도 화방이 연속으로 출뢰하여 다수확용으로 적당한 사계성딸기 품종이다.
