‘Zasoojeongchal’ is a new colored naked barley cultivar developed from the cross between HB83072〔Tapgolbori / HB 78100-B-17-3-2〕, a disease resistant and good quality line and ‘Dokusima mochi hadaka’, colored naked cultivar with waxy endosperm by the Honam Agricultural Research Institute (HARI), NICS, RDA in 2006. An elite line CNB7-13-37-2-5-3, was selected in 2002 and designated as ‘Iksan 81’. It showed good agronomic performance in the regional yield trials (RYT) from 2005 to 2006 and was released with the name of ‘Zasoojeongchal’ possessing purple colored waxy endosperm. The average heading and maturing dates of ‘Zasoojeongchal’ were May 2 and Jun. 7, which were two and five days later than those of the check cultivar ‘Saechalssalbori’ respectively. The new cultivar, ‘Zasoojeongchal’, had 75cm of culm length that was 4cm shorter than that of ‘Saechalssalbori’, and 5.4 cm of spike length. It showed 607 spikes per m2, 63 grains per spike, 27.2 g of 1,000-grain weight, and 771 g of test weight. ‘Zasoojeongchal’ showed weaker winter hardiness, but better resistance to powdery mildew and BaYMV (Barley yellow mosaic virus) than those of the check cultivar, ‘Saechalssalbori’. It showed higher ß-glucan content, anthocyanin content, water absorption rate and expansion rate than those of the check cultivar, ‘Saechalssalbori’. Its average yield of the pearled grain in the regional yield trial was 2.67 MT/ha in upland, and 3.49 MT/ha in paddy field, which were 26% and 6% lower than those of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum temperature of -6℃ in January in Korean peninsula.
