신품종 ‘보석찰’쌀보리는 안토시아닌 함량이 높은 자색 찰성 쌀보리 신품종으로 국립식량과학원에서 도복과 내한성이 강하고 찰성으로 립백도와 정맥율이 높으며 취반특성이 우수한 특성을 지닌 ‘찰쌀보리’와 ‘함안군북찰쌀보리’를 인공교배한 후 계통육종법으로 육성하였다. 전작 및 답리작 지역적응시험을 실시한 결과 답리작 적응성이 높으며, 도복 등 내재해성에 강한 특성과 안토시아닌 함량이 높은 자색영을 가진 계통임이 입증되었다. 출수기는 전작에서 새찰쌀보리보다 1일 빨랐으며, 답리작은 새찰쌀보리와 같았고, 성숙기는 전작과 답리작에서 새찰쌀보리와 같았다. 간장은 87 cm, 수장 5.0 cm, m2당 수수는 601개로 새찰쌀보리보다 많았고, 천립중은 29.0 g으로 소립종이었다. 단백질 함량은 표준품종인 새찰쌀보리와 비슷하였다. 안토시아닌 함량은 180.1 ㎍/g이었으며, β-glucan과 아밀로스는 새찰쌀보리와 비슷하였으며, 흡수율과 퍼짐성은 다소 높았다. 수량성은 전작에서 3.44 MT/ha, 답리작에서 3.56 MT/ha이었다.

A new six-rowed hull-less barley cultivar ‘Boseokchal’ with high anthocyanin content and purple lemma was developed from the cross between ‘Chalssalbori’ and ‘Hamangunbuk Chalssalbori’ by National Institute of Crop Science, RDA in 2008. ‘Chalssalbori’ has good winter hardness, lodging tolerance, and cooking property and ‘Hamangunbuk Chalssalbori’ possess waxy endosperm and purple lemma. An elite line CNY121-B-94323 was selected in 2003 and designated as ‘Iksan 87’. It showed good agronomic performance in the regional yield trials (RYT) from 2006 to 2008 and was released with the name of ‘Boseokchal’possessing high anthocyanin content and purple lemma waxy endosperm. The average heading and maturing dates of ‘Boseokchal’were April 23 and May 29 in paddy field, which were one day earlier and same compare with those of the check cultivar ‘Saechalssalbori’ respectively. It had 87 cm of culm length and 5.0 cm of spike length. It showed 601 spikes per m2, 61 grains per spike, 29.0 g of 1,000-grain weight, and 780 g of test weight. ‘Boseokchal’ showed better resistance to BaYMV (Barley yellow mosaic virus) and higher water absorption rate and expansion rate than those of the check cultivar. Its average yield of the pearled grain in the regional yield trial was 3.44 MT/ha in upland, and 3.56 MT/ha in paddy field, which were 5% lower and 1% higher than those of the check cultivar, respectively. Anthocyanin content was 180 ㎍/g that was higher than that of the check cultivar.
