초록

신품종 '누리찰'은 찰성 쌀보리 신품종으로 국립식량과학원에서 계통육종법으로 육성하였다. 3개 지역에서 답리작 지역적응시험을 실시한 결과 답리작 적응성이 높으며, 쓰러짐에 강하고 수량이 7-16% 증가된 보리밥 특성이 좋은 계통임이 입증되었다. 출수기와 성숙기는 답리작에서 새찰쌀보리보다 각각 1일 늦었다. 간장은 82 cm로 중장간, 수장 4.0 cm, $m^2$당 수수는 774개로 새찰쌀보리와 많았으며 천립중은 25.0 g으로 새찰쌀보리보다 가벼웠고 도복에 강하고 보리호위축병에 저항성을 보였다. 단백질 함량은 새찰쌀보리보다 적었고, ${\beta}-glucan$, 전분, 아밀로스 함량은 새찰쌀보리와 비슷하였다. 흡수율은 비슷하였고 퍼짐성은 다소 높았다. 호화특성은 최고점도가 높고 치반점도가 낮았으며, 보리밥 물성은 경도, 탄력성, 저작성이 새찰쌀보리보다 낮아 보리밥이 다소 부드러운 특성을 보였다. 평균수량성은 답리작에서 4.00 MT/ha로 새찰쌀보리보다 10% 증가하였다.

"Nulichal" was developed by the National Institute of Crop Science, RDA, in 2010. The initial cross was conducted in 2000, and an elite line (HB15305-B-B-31-2) was selected in 2005. Subsequently, preliminary yield and advanced yield trials have designated it as "Iksan 95." It showed good agronomic performance in regional yield trials from 2008 to 2010 and was released as "Nulichal," with resistance against the barley yellow mosaic virus (BaYMV) and high yields with a waxy endosperm. The average heading and maturation dates of "Nulichal" were April 24 and May 30, respectively in paddy fields, which were 1 day later than those of the check cultivar "Saechalssalbori." It had culm and spike lengths of 82 and 4.0 cm, respectively. It showed $774spikes/m^2$, 63 grains/spike, 25.0 g of 1,000-grain weight, and 793 g of test weight. "Nulichal" showed higher levels of resistance to BaYMV than the naturally occurring Iksan (type III strain), Naju (type I), and Jinju (type II). The expansion rate was higher than that of "Saechalssalbori" and its hardness, gumminess, and chewiness were lower than those of "Saechalssalbori." Its average pearled grain yield in the regional yield trial was 4.00 MT/ha in paddy fields, which was 10% higher than that of the check cultivar. The combined availability of "Nulichal" was improved by its increased culm length compared with that of "Hinchalssal."
