‘Baeksoojeongchal’, a new naked waxy barley cultivar was developed from a cross between ‘Jinmichapssal’ and ‘Radiant’ at the National Institute of Crop Science, RDA in 2019. ‘Baeksoojeongchal’ is a white, waxy naked barley cultivar with a low browning reaction owing to the low levels of proanthocyanidin. Regional yield trials were conducted for ‘Baeksoojeongchal’ as the breeding line, ‘Jeonju135’ at four different regions between 2017 and 2019. The average heading date of ‘Baeksoojeongchal’ in the paddy field was April 20, which was a day later than that of ‘Saechal’. Maturing date of ‘Baeksoojeongchal’ in the paddy field was May 26, which was 2 days later than that of ‘Saechal’. It has a short culm length of 75 cm and a short spike length of 4.3 cm, with 48 grains per spike and a 1,000-grain weight of 29.5 g. Compared to ‘Saechal’, ‘Baeksoojeongchal’ shows weaker winter withering and has better tolerance to lodging. The incidence of BaYMV (Barley yellow mosaic virus) in ‘Baeksoojeongchal’ was similar to that in ‘Saechal’; in addition, it was susceptible to powdery mildew. The grain quality characteristics of ‘Baeksoojeongchal’ indicated a similar protein content (9.6%) and a lower proanthocyanidin content (0.011%) and whiteness (42.0) compared to that in ‘Saechal’. The average yield was 505 kg/10a in the paddy field, which was 7% higher than that of ‘Saechal’. ‘Baeksoojeongchal’ is the naked waxy barley cultivar with the most whiteness and low proanthocyanidin content; therefore this could contribute to the promotion of barley consumption, by avoiding reduction in consumer preference (Registration No. 9194).

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).

Hordeum vulgare ‘Heukbochal’, a naked waxy barley cultivar with a high anthocyanin content and black lemma has been developed from a cross between ‘Ginssalbori/Changyongjaelae’ and ‘Ginssalbori’ by the National Institute of Crop Science, RDA. It is a winter-type barley with a vernalization degree of Ⅳ, lax panicle with loose-type spike density, and long awn type. The average heading date of ‘Heukbochal’ is April 19^th, which is the same as that of the control cultivar ‘Saechalssalbori’. It has a long culm of 79 cm and a long spike length of 7.0 cm, with 54 grains per spike and a 1000-grain weight of 30.4 g. Although compared with ‘Saechalssalbori’, ‘Heukbochal’ shows weaker winter hardiness, it is characterized by better resistance to barley yellow mosaic virus. The grains of ‘Heukbochal’ showed a similar protein content (10.4%) to ‘Saechalssalbori’ but a lower beta-glucan content (5%) than that of ‘Saechalssalbori’. Furthermore, the grains of ‘Heukbochal’ have an anthocyanin content of 0.116±0.005 mg/bran g, which is 1.9 times higher than that of ‘Heuknuri’ (0.062±0.007 mg/bran g), another non-waxy naked barley cultivar with a black lemma. Additionally, its average grain yield is 4.02 ton/ha in paddy fields, which is 5% lower than that of ‘Saechalssalbori’. ‘Heukbochal’ is the first developed naked waxy barley cultivar with a high anthocyanin content and black lemma; therefore, we anticipate its cultivation in Korea (Registration No. 8194).

As a result of the efforts to breed a high yield naked barley cultivar with disease and stress tolerance in response to climate change and proper double cropping of barley and rice in a paddy field. A new naked barley cultivar named ‘Hogang’ was developed from the cross between ‘Suyoung’ and ‘Geukjosuk 55’ at the National Institute of Crop Science, RDA, Korea, in 2016. ‘Hogang’ is a naked barley cultivar used for powdering and mixing with rice. It has good cooking quality, high whiteness, water absorption rate, and expansion rate. Among other quality characteristics, β-glucan content (5.5%) was higher than that of ‘Saessalbori’ cultivar, while the amylose content (21.7%) was lower than that of ‘Saessalbori’. ‘Hogang’ has a short culm length of 69 cm and it is resistant to BaYMV as well as lodging-resistant. As in ‘Saessalbori’, the maturity date of ‘Hogang’ is May 26^th. It has large seed size and grain weight of 34.6 g per 1,000 grains. The yield potential of ‘Hogang’ was 4.56 MT/ha, which was 7% higher than that of ‘Saessalbori’. ‘Hogang’ is expected to spread in BaYMV-prone areas since it is a stable and resistant cultivar.

A new black barley variety, “Heuksoojeongchal,” was developed as a cross between “Keunalbori 1” and “Masankwamaek/Mortoni” at the National Institute of Crop Science, RDA in 2014. Heuksoojeongchal had a longer culm length (89 cm) and a later average heading date and maturity than Seodunchalbori. It also had a spike length of 5.0 cm, 543 spikes/m², and 54 grains/spike. The 1000-grain weight of Heuksoojeongchal (36.0 g) was heavier than that of Seodunchalbori. Heuksoojeongchal showed resistance to barley yellow mosaic virus (BaYMV). The yield potential of Heuksoojeongchal was approximately 7% higher than that of Seodunchalbori upland, but the average yield potential was similar in upland and paddy fields. Among the quality characteristics, the β-glucan content (6.7%) was higher and the amylose content (5.5%) was lower than those of Seodunchalbori. The whiteness of the black barley was low, and its absorption rate and spreadability were similar to those of Seodunchalbori.

Consumer interest in nutrition and health has increased, for other food and industrial applications, including for barley. ‘Huknuri’ is a new naked non-waxy barley cultivar with black lemma. It was developed by the National Institute of Crop Science, RDA, in 2011. The initial cross was carried out in 2002, and an elite line (HB16225-B-B-9) was selected in 2006. Since then, through preliminary yield and advanced yield trials, it was designated as ‘Iksan 100’. It showed good agronomic performance in the regional yield trials from 2009 to 2011 and was released as ‘Huknuri’, possessing high anthocyanin content and black lemma with a non-waxy endosperm. The average heading and maturing dates of ‘Huknuri’ were April 23 and May 29 in paddy fields, which were one day earlier and the same as those of the check cultivar ‘Saessalbori’, respectively. It had a culm and spike length of 87 and 5.0 cm, respectively. It showed 601 spikes per m², 61 grains per spike, 29.0 g of 1,000-grain weight, and 780 g of test weight. ‘Huknuri’ showed better resistance to Barley yellow mosaic virus and higher water absorption and expansion rates than those of the check cultivar. Its average pearled grain yield in the regional yield trial was 3.44 MT/ha in upland, and 3.56 MT/ha in paddy fields, which were 5% lower and 1% higher than those of the check cultivar, respectively. The anthocyanin content was 180 µg/g, which was higher than that of the check cultivar.

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 cm which was 4 cm shorter than ‘Olbori’. It showed the spike length of 4.0cm and 557 spikes/m². 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’.
