초록

'흑수정찰'은 도복에 강한 흑색 찰성 보리로 육성된 품종으로 파성은 III이며 이삭의 밀도는 밀수형이고, 까락이 긴 장망형으로 출수기는 4월 29일로 조숙종인 서둔찰보리보다 3일, 성숙기는 6월 3일로 3일 정도 늦었다. 간장은 89 cm로 서둔찰보리(82 cm) 대비 7 cm 크고, 수장은 5.0 cm로 서둔찰보리(4.4 cm)보다 컷다. $m^2$ 당 수수는 543개로 서둔찰보리보다 적었다. 1수립수 54립, 천립중(36.0 g)은 무거웠다. 리터중(622 g)은 서둔찰보리보다 가벼웠다. 토양 전염 바이러스병인 보리호위축병은 저항성이었으며, 한해는 서둔찰보리보다 약하였으나 도복은 강하였다. 품질특성 중 베타글루칸 함량(6.7%)은 서둔찰보리에 비해 높았으며 아밀로스 함량(5.5%)은 낮았다. 흑색 찰성 보리로서 백도는 낮았으나 흡수율과 퍼짐성은 비슷하였다. 수량성은 전작 재배지역에서 높았으나 전체지역 평균의 수량성은 4.33 MT/ha으로 서둔찰보리와 비슷하였다.

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, $543spikes/m^2$, 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 ${\beta}-glucan$ 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.
