초록
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-temperaturetolerant ‘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’ was9.1 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 slightlyheavier 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’ was892 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 andthat 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’, andit shows tolerance to drought or high temperature. ‘Arirang-2’ was approved as a new potato cultivar by The Korea Seed and Varieties Serviceon March 3, 2021 (Registration No. 8444).
Abstract
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-temperaturetolerant ‘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’ was9.1 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 slightlyheavier than that of ‘Superior’ (90.0 g), and much heavier than that of ‘Sante’ (38.9 g).
