영문 초록

‘Daegwang’ was developed in a potato breeding program at the Highland Agriculture Research Institute, National Institute of Crop Science, Rural Development Administration, South Korea. It was selected from the hybrid ‘Haryeong’בP03404-1’ from 2007. In 2011-2012, the major agronomic characteristics of this variety were evaluated in Gangneung for spring cultivation and Pyeongchang for summer cultivation as clone number ‘P07917-4’. ‘P07917-4’ was renamed as ‘Daegwan 1-127’, and regional yield trials for this clone were conducted in Cheongju, Naju, Gangneung, and Pyeongchang in 2013-2015. This cultivar was registered as ‘Daegwang’, based on its key agronomic characteristics, including drought tolerance, late blight resistant, and high yield. It has medium maturity and a semi-erect growth habit. ‘Daegwang’ has a round to short oval tuber shape, shallow eye-depth, yellow skin color, and white flesh color. Its leaf color is green, and its white flowers bloom abundantly. This cultivar is resistant to potato late blight but susceptible to potato common scab. The incidences of hollow heart and internal brown spot were low. However, the frequency of tuber cracking was high, at about 6.0% in summer cultivation in Pyeongchang. In the regional yield trials, ‘Daegwang’ had an average tuber yield of 34.1 ton/ha, which was 6.2% higher than that of ‘Sumi’, and its dry matter content was 16.8%. Boiled ‘Daegwang’ tubers have a viscous-floury texture and a pleasant taste. ‘Daegwang’ is expected to be produced as a table potato. (Registration No. 7664).
