A new strawberry (Fragaria×ananassa Duch.) cultivar ‘Highberry’ was developed by Strawberry Research Institute of Chungcheongnam-do Agricultural Research and Extension Services for forcing culture in 2018. In order to breed a new cultivar that is favorable to export with high fruit firmness and maintain the fruit quality during warm temperatures in the spring season, ‘Highberry’ originated from a cross between an unreleased selection ‘NS071608’ (female parent) with high firmness and ‘Daewang’ (male parent) with good taste and fragrance in 2013. In 2014－2017, it was originally named ‘Nonsan No. 12’ by conducting seedling selection, growth characteristics and production trials in forcing culture, and it was renamed ‘Highberry’ in 2018. ‘Highberry’ shows an erect plant type and vigorous growth habit. The leaves are dark green and thick and the leaf shape is elliptic. Fruits are conical type; fruit color is red. The first cluster of ‘Highberry’ has 13 flowers, and it is a large fruit size cultivar with an average fruit weight of 16 g. The marketable yield of ‘Highberry’ was 2,623 kg·10a⁻¹, which is 97% of that of ‘Sulhyang’. The flower stem length of ‘Highberry’ was 37 cm long and is divided into two stems from the bottom. Fruit firmness of ‘Highberry’ was 15.3 g·mm⁻², which was 3.6 g·mm⁻² higher than 11.7 g·mm⁻² of ‘Sulhyang’ and can be harvested until late spring. The soluble solids content of ‘Highberry’ was 10.1°Brix, which was 0.6°Brix higher than that of ‘Sulhyang’. ‘Highberry’ is resistant to Fusarium wilt but susceptible to powdery mildew and two-spotted spider mites.
