Hull-less Waxy Barley (Hordeum vulgare L.) Cultivar ‘Boseokchal’ with High Anthocyanin Content and Purple Lemma

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.
