수출용 촉성재배 딸기 신품종 ‘홍실’ 육성

Breeding of New Cultivar ‘Hongsil’ in Forcing Culture of Strawberry for Export

‘홍실(Hongsil)’ 품종은 경상남도농업기술원에서 2015년육성한 촉성재배용 딸기 신품종이다. ‘802a312’를 모본으로하고 ‘옥매(Okmae)’를 부본으로 하여 2011년 교배하여 과실의당도와 경도가 높아 수출용으로 적합한 개체로 선발한 것이다 2013-2014년에 촉성재배 작형으로 특성 및 생산력검정 결과 우량계통으로 ‘1116-74-15’를 선발하였고, 2015년 농가 실증 시험을 거쳐 ‘홍실’로 명명하였다. ‘홍실’의 초형은 반개장형으로초세는 중간 정도이다. 휴면이 얕고 화아분화가 빨라서 촉성재배에 적합한 품종이다. 과실의 당도는 10.0 °Brix로 ‘설향’보다0.4 °Brix가 더 높았으며, 경도는 13.1 g·㎜-2로 ‘매향’과 비슷하였다. ‘홍실’의 과실은 장원추형으로 과색은 선홍색이며 상품수량은 4,269 ㎏· 10a-1으로 ‘매향’보다 16% 더 많았다. 병저항성은 흰가루병에 다소 약하므로 방제에 유의하여야 한다.

The ‘Hongsil’ strawberry (Fragaria × ananassa Duch.) is a new cultivar released by Gyeongsangnam-do Agricultural Research & Extension Services in 2015. This cultivar originated from a 2011 cross between ‘802a312’ and ‘Okmae’ and exhibited suitable fruit characteristics for export due to the high soluble solids content and firmness of the fruit. The breeding line ‘1116-74-15’ was selected as an elite line after examining its characteristics and productivity from 2013 to 2014. A field trial of this line was conducted on a farm in 2015, and it was registered as ‘Hongsil’ thereafter. The ‘Hongsil’ strawberry demonstrates intermediate plant type and moderate vigor in growth. It is suitable for forcing culture due to its early flower bud differentiation and low chilling requirement. The soluble solids content of ‘Hongsil’ is 10.0 °Brix, which is approximately 0.4 °Brix higher than that of ‘Seolhyang’ The Fruit firmness of ‘Hongsil’ is 13.1 g·㎜-2 , similar to that of ‘Maehyang’. Fruits of ‘Hongsil’ are long conical having a red skin color and marketable yield is 4,269 ㎏·10a -1 which is 16% higher than that of ‘Maehyang’. The ‘Hongsil’ cultivar is sensitive to powdery mildew, and it therefore warrants further investigation regarding disease control.
