In 2013, a strawberry variety ‘Altaking’ was derived as an artificial cross between ‘12-S-4’ (with high firmness) and ‘Ssanta’ (with high sugar content). Seedling and line selections were conducted from 2013-2015. Preliminary and advanced yield trials of ‘13-S-6-3,’ which was the final selected line, were conducted from 2015-2017. The general characteristics of ‘Altaking’ include upright growth habit, elliptical leaves, and strong vigorous growth. The fruit is long, conical, and light-red in color. The average number of flowers per flower cluster was 12.1, which could reduce the labor required for fruit thinning. This variety is suitable in forcing culture because of its early flower-bud differentiation (September 1), early first harvest (mid of November), and continuous formation of the next flower cluster. ‘Altaking’ has adequate characteristics for exportation because the sugar content rises in the early stages of color development. Although ‘Altaking’ and ‘Seolhyang’ have similar sugar content, the former is less sour, thus making it taste sweeter. ‘Altaking’ has a unique flavor and it smells like peach. The fruit weighs approximately 35.1 g, and it should be harvested at 80% coloration to intensify its deep flavor. In 2019, ‘Altaking’ was registered with the Korea Seed and Variety Service (KSVS) for plant variety protection (Registration No. 7854).
