Abstract
“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 774 spikes/m2, 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.”
