‘Saebong’ is a double cropping potato variety bred by the Highland Agriculture Research Institute, NICS, RDA, in 2010. Although the major double-cropped potato cultivar of Korea, cv. Dejima, with a dormancy period of 50-60 days after harvest was introduced in 1978, it is susceptible to physiological disorders, such as abnormal tubers and cracking, and common scab. The ‘Chubaek’ variety matures very early and has a dormancy period similar to that of cv. Dejima, yet it is highly susceptible to potato virus Y and has a low dry matter content. ‘Saebong’ was obtained by crossing ‘Daegwan2-8’ with ‘DH9-231’ in 2002. Seedling and line selections were performed from 2003-2004, and yield trials were carried out from 2005-2006 in Gangneung and Pyeongchang. Regional yield trials were conducted in spring and autumn in Namhae, Jeju, and Gangneung from 2007-2008 and in Muan, Jeju, and Gangneung in 2009. This variety produces many white flowers and berries, narrow green leaflets and petioles, and round tubers with beige-colored skin and white-colored flesh. Its dormancy period, when stored at 20℃, was 50-60 days after harvest in spring, similar to cv. Dejima and Chubaek. The average tuber yields in spring and autumn regional trials were 40.4 and 30.5 ton⋅ha^-1, respectively. It is susceptible to common scab but highly resistant to potato leafroll virus and potato virus Y. Its dry matter content was 21.56% and 20.60% in spring and autumn, respectively (similar to those of cv. Atlantic and cv. Goun). It produces brighter colored potatoes and can be used to process potato chips and table stock after autumn cultivation in the potato double cropping area of Korea (Registration No. 4873).

In 2018, a new potato variety, ‘Arirang-2’, was released by the Highland Agriculture Research Institute in Pyeongchang, Korea. To create new varieties with better tuber formation at high temperature under long day, a cross was performed between high-temperature tolerant ‘Eigenheimer’ and drought tolerant ‘Daegwan 1-116’ in 2011. The shoot (57.9 cm) of ‘Arirang-2’ was taller than ‘Superior’ and ‘Sante’, and its tuber skin and flesh were red and light-yellow colored, respectively. Average number of tubers per plant of ‘Arirang-2’ was 9.1 while ‘Superior’ and ‘Sante’ had 5.4 and 14.1 tubers, respectively. Average weight of tuber of ‘Arirang-2’ was 98.1 g, which was slightly heavier than that of ‘Superior’ (90.0 g), and much heavier than that of ‘Sante’ (38.9 g). Total weight of tuber per plant of ‘Arirang-2’ was 892 g, which was remarkably higher than that of ‘Superior’ (486 g) and ‘Sante’ (549 g). Total yield (TY) of ‘Arirang-2’ measured in Gangwon-Do, Korea was around 5,022 kg/10a while that of ‘Superior’ was 3,036 kg/10a. In Kazahstan, total yield of ‘Arirang-2’ was 4,657 kg/10a and that of ‘Sante’ was 4,155 kg/10a. Marketable tuber yield (MTY) of ‘Arirang-2’ was 3,119 kg/10a in Gangwon-Do, Korea while that of ‘Superior’ was only 2,147 kg/10a. In Kazahstan, MTY of ‘Arirang-2’ was 3,162 kg/10a, which was 60% higher than that of ‘Sante’ (1,974 kg/10a). ‘Arirang-2’ is resistant to early blight (Alternaria solani) and late blight (Phytophthora infestans) compared to ‘Superior’ and ‘Sante’, and it shows tolerance to drought or high temperature. ‘Arirang-2’ was approved as a new potato cultivar by The Korea Seed and Varieties Service on March 3, 2021 (Registration No. 8444).
