영문 초록

A new covered barley cultivar ‘Hangang’ with resistance to barley yellow mosaic virus (BaYMV) and tolerance to cold was developed by crossing ‘Samkwangchal/Radiant’ at the National Institute of Crop Science, RDA in 2018. The regional yield trials were conducted for ‘Hangang’ as a breeding line ‘Jeonju498’ in five different regions from 2016 to 2018. The average heading date of ‘Hangang’ was April 22, which was one day earlier than that of ‘Olbori’. The maturing date of ‘Hangang’ was May 30, which was similar to that of ‘Olbori’. The culm length was 81 cm, which was shorter than that of ‘Olbori’, showing tolerance to lodging stress. ‘Hangang’ showed the spike length of 4.6 cm with 669 spikes per m2, 54 grains per spike, and a weight of 33.5 g for 1,000 grains. Compared with ‘Olbori’, ‘Hangang’ showed stronger withering in winter (winter hardiness) and resistance to BaYMV. Among quality characteristics, ‘Hangang’ showed similar levels as those of ‘Olbori’ with respect to protein, β-glucan and amylose (10.7%, 4.6%, and 18.8%, respectively). However, ‘Hangang’ showed higher polyphenol content (1.69 mg/g) than the check cultivar. The yield of ‘Hangang’ in the regional yield trial was 611 kg/10a in upland, 502 kg/10a in paddy field, and an overall average of 567 kg/10a, which was 15%, 16% and 16% higher than that of the check cultivar, respectively. Therefore, ‘Hangang’ will be suitable cultivar when sowed in cold regions (Registration No. 8773).
