영문 초록

A new black barley variety, ‘Heukdahyang’, was developed from the cross between ‘Keunalbori 1ho’ and ‘Masankwamaek/Mortoni’ at the National Institute of Crop Science, RDA in 2015. ‘Heukdahyang’ had a shorter culm length (76 cm) than that of ‘Olbori’, and had lodging tolerance. The average heading and maturity dates of ‘Heukdahyang’ were April 28 and June 2, respectively, which were later than those of ‘Olbori’. ‘Heukdahyang’ also had a spike length of 5.1 cm, spike density of 534 spikes/m2, and 57 grains/spike. The thousand grain weight of ‘Heukdahyang’ (35.9 g) was greater than that of ‘Olbori’. ‘Heukdahyang’ showed moderate resistance to barley yellow mosaic virus. The yield potential of ‘Heukdahyang’ was about 6% higher than that of ‘Olbori’ in upland and paddy fields. Among qualitative characteristics, protein and β-glucan content of ‘Heukdahyang’ were 11.3% and 4.7%, respectively, which were similar to those of ‘Olbori’. However, ‘Heukdahyang’ showed higher polyphenol content (0.162%) and higher DPPH radical scavenging activity than those of the check cultivar (Registration No. 7007).
