Abstract

'Miha' is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2019. The 'Miha' cultivar originates from a 2014 cross between 'Monterey' and 'Saebong No. 3', 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. 12' after examining its characteristics and productivity during summer cultivation between 2015 and 2019. After regional adaptability tests, 'Miha' was selected from 'Saebong No. 12' as an elite cultivar. The general characteristics of 'Miha' include intermediate, elliptic leaves, and strong growth. The fruits are conical and of a dark-red color. The number of leaves of 'Miha' was 21.9, which was 6.2 fewer than that of the control cultivar, 'Goha' with 28.1. The number of flower clusters of 'Miha' was similar to that of 'Goha'. The average fruit weight of 'Miha' was 13.4 g, which was 4.3 g heavier than that of 'Goha'. The fruit hardness of 'Miha' was 36.2 g·mm-2, which was 10.1 g·mm-2 harder than that of 'Goha'. The marketable yield of 'Miha' was 37,393 kg·ha-1, 156% more than that of 'Goha' with 23,970 kg·ha-1. Therefore, the new cultivar of ever-bearing strawberry 'Miha' is expected to be very popular in the export or bakery market because it is hard.

여름재배용 사계성 딸기 '미하'(Fragaria x ananassa Duch.) 품종은 2019년 농촌진흥청 국립식량과학원 고령지농업연구소에서 육성되었다. 2014년 경도가 높고 대과성인 중일성 딸기 품종 '몬테레이'를 모본으로 하고, 경도가 높고 고온에 강한 사계성 딸기 계통 '새봉3호'를 부본으로 하여 교배하였다. 2015년 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 2016년 우수계통 선발, 2017년 생산력검정, 2018년 특성검정, 2019년 지역적응성 검정을 수행하였다. 시험결과 경도가 높고 대과성으로 품종육성 목표에 가장 근접한 이 계통을 '새봉 12호(15-28-57)'로 계통명을 부여하였다. 2019년 직무육성 품종 선정위원회에서 신품종으로 선정되어 '미하(Miha)'로 명명되었다. '미하'의 초형은 반개장형이며, 초세가 강하다. 과실 모양은 원추형이며, 과색은 진홍색이다. '미하'의 엽수는 21.9매로 대조품종인 '고하'의 28.1매보다 6.2개 적었다. 그러나 '미하'의 화방당 화수는 대조품종인 '고하'와 비슷하였다. '미하'의 평균과중은 13.4 g으로 '고하'의 9.1 g보다 4.3g 더 무거운 대과성 품종이다. 또한 경도는 36.2 g·mm-2로 '고하'보다 10.1g·mm-2 더 단단하다. '미하'의 상품수량은 37,393 kg·ha-1로 '고하'의 23,970 kg·ha-1보다 156% 증수되었다. 따라서 신품종 사계성 딸기 '미하'는 단단하여 수출용 또는 제과용 시장에서 큰 인기가 있을 것으로 기대된다.
