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 19th, 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).
