Purple Covered Waxy Barley (Hordeum vulgare L.) Cultivar, ‘Boanchal

‘Boanchal’, a new covered waxy barley cultivar derived from crossing the ‘Suwon232’ and ‘Masangwamaeg’ with early maturing and colored waxy endosperm cultivars, respectively was developed at the National Institute of Crop Science, RDA in 2009. ‘Boanchal’ is characterized as the growth habit of Ⅲ, green leaf, medium spike and long rough awns. The heading date was April 24 in upland and April 17 in paddy field which was 2 and 1 day, respectively earlier than check cultivar, ‘Seodunchal’. The culm length of ‘Boanchal’ was 79 cm, which was 11 cm shorter than that of check cultivar. It showed spike length of 3.5cm, 854 spikes per m2, 43 grains per spike, and 28.0 g of 1,000-grain weight. Comparing to check cultivar, ‘Boanchal’showed stronger winter hardiness, but a similar resistance to barley yellow mosaic virus (BaYMV). It had purple grain and showed higher expansion rate than that of check cultivar, ‘Seodunchal’. Average yield of ‘Boanchal’ in the regional adaptation yield trial (RYT) was 2.96 MT/ha in upland and 3.91 MT/ha in paddy field. ‘Boanchal’ would be suitable for the area above -8℃ of daily minimum temperature in January in Korean peninsula.
