Abstract
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.
