Abstract

'Jinha' is a new strawberry (Fragaria × ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2019. The 'Jinha' cultivar originates from a 2011 cross between 'Albion' and 'Goha,' both of which exhibited excellent ever-bearing characteristics, including continuous flowering and large fruits under long-day and high temperature conditions. This new cultivar was initially named 'Saebong No. 11' after examining its characteristics and productivity during summer cultivation between 2012 and 2016. After regional adaptability tests, 'Jinha' was selected from 'Saebong No. 11' as an elite cultivar. The general characteristics of 'Jinha' include intermediate, elliptic leaves, and medium growth. The fruits are conical and of a red color. The plant height of 'Jinha' is simiar to that of the control variety, 'Flamenco', but it has a lot of number of leaves. The cluster length of 'Jinha' was 35.5 cm, 10.8 cm longer than 24.7 cm of the control variety. The number of flower clusters of 'Jinha' appeared 14.4, which was 4.1 more than that of 'Flamenco'. The average fruit weight of 'Jinha' was 10.1 g, which was 0.8 g heavier than that of 'Flamenco'. The soluble solid content of 'Jinha' was 10.2 °Brix, which was 2.0 °Brix higher than that of 'Flamenco'. The marketable yield of 'Jinha' was 25,931 kg·ha-1, 440% more than that of 'Flamenco' with 5,900 kg·ha-1. Therefore, the new cultivar of ever-bearing strawberry 'Jinha' is expected to be very popular in the export or bakery market because it is high soluble solid content and good shape.

여름재배용 사계성 딸기 '진하'(Fragaria × ananassa Duch.) 품종은 2019년 농촌진흥청 국립식량과학원 고령지농업 연구소에서 육성되었다. 2011년 경도가 높고 대과성인 중일성 딸기 품종 'Albion'을 모본으로 하고, 모양이 좋고 고온에 강한 사계성 딸기 품종 '고하'를 부본으로 하여 교배하였다. 2012년 파종 후 육묘하여 4월 정식하였다. 정식 후 사계성, 과실크기, 경도, 당도 등을 조사하여 사계성이며, 경도가 높고 수량성이 높을 것으로 예측되는 1개체를 실생선발하였다. 본 계통을 여름작형에서 2013년 우수계통 선발, 2014년 생산력검정, 2015년 특성검정, 2016년 지역적응성 검정을 수행하였다. 시험결과 당도가 높아 맛이 좋으며, 품종육성 목표에 가장 근접한 이 계통을 '새봉 11호(12-6-561)'로 계통명을 부여하였다. 2019년 직무육성품종 선정위원회에서 신품종으로 선정되어 '진하(Jinha)'로 명명되었다. '진하'의 초형은 반개장형이며, 초세는 중간이다. 과실모양은 원추형이며, 과색은 홍색이다. '진하'의 초장은 대조품종 'Flamenco'와 비슷하나 엽수가 많은 편이다. 그러나 화방장은 35.5 cm 대조품종인 'Flamenco'의 24.7 cm보다 10.8 cm 더 길다. 또한 화방수는 14.4개가 출현되어 대조품종보다 4.1개가 더 발생된다. '진하'의 평균과중은 10.1 g으로 'Flamenco'의 9.3 g보다 0.8 g 더 무겁다. 또한 당도는 10.2 °Brix로 'Flamenco'보다 2.0°Brix 더 높다. '진하'의 상품수량은 25,931 kg·ha-1로 'Flamenco'의 5,900 kg·ha-1보다 훨씬 많지만 일반적인 사계성 딸기품종 수량과 유사하다. 따라서 신품종 사계성 딸기 '진하'는 다른 사계성 품종보다 당도가 높고 모양이 좋아 제과용 시장에서 큰 인기가 있을 것으로 기대된다.
