Covered Barley(Hordeum vulgare L.) Variety, ‘Cheongmyeong’ With High Anthocyanin Content and Green Aleurone Layer

Improvement of lodging resistance and adaptable to double cropping system, high yield and good quality have been recently received more attention by covered barley(Hordeum vulgare L.) breeders than ever in Korea. It was derived from the cross between ‘Dongsanpi73//Suwon248/ Alchanbori ‘and‘Suwon375’ in 2004. An elite line (SB04T1014-B-2SSD-B-6 (Iksan468)), showed high yield and good quality characteristics under yield trial test from 2012 to 2014. The following is the characteristics of ‘Cheongmyeong’, that is characterized as the vernalization of Ⅱ, compact panicle and long awn. The heading date of ‘Cheongmyeong’ was 2 days later than ‘Olbori’ but it showed similar maturity date. The culm length was 79 ㎝ which was 4 ㎝ shorter than ‘Olbori’. It showed the spike length of 4.0㎝ and 557 spikes/㎡. The number of grains per spike was 53 grains and test weight was 651 g. It showed higher number of grains per spike and lighter test weight than ‘Olbori’. It showed weak winter hardiness, stronger resistance to barley yellow mosaic virus(BaYMV) and lodging compared to ‘Olbori’. It showed similar protein and β-glucan content, and higher anthocyanin and polyphenol content than that of check cultivar, ‘Olbori’. Average yield of ‘Cheongmyeong’ was 4.30 MT/ha in the regional yield trials, which was 7% higher than those of ‘Olbori’.
