Abstract

‘Eunha’ is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2023. The ‘Eunha’ cultivar originates from a 2016 cross between ‘Portola’ 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. 15’ after examining its characteristics and productivity during summer cultivation between 2017 and 2022. After regional adaptability tests, ‘Eunha’ was selected from ‘Saebong No. 15’ as an elite cultivar. The general characteristics of ‘Eunha’ include semi-upright type, and strength vigor in growth. The fruits are conical and of a red color. The plant height of ‘Eunha’ is simliar to that of the control variety, ‘Goha’, but it has a lot of number of leaves. The number of flower clusters of ‘Eunha’ was 9.5, 4.6 less than 14.1 of the control variety. The average fruit weight of ‘Eunha’ was 12.2 g, which was 2.6 g heavier than that of ‘Goha’. The soluble solid content of ‘Eunha’ was 10.9 °Brix, which was 1.0 °Brix higher than that of ‘Goha’. The marketable yield of ‘Eunha’ was 27,499 ㎏·㏊^-1, 153 % more than that of ‘Goha’ with 17,911 ㎏·㏊^-1. Therefore, the new cultivar of ever-bearing strawberry ‘Eunha’ is expected to improve income when supplying farms as it has high soluble solid content and can be produced stably at high temperatures.
