Abstract
"Youhan" (Hordeum vulgare L.), a new whole-crop barley cultivar, was developed by the breeding team at National Institute of Crop Science, RDA in 2012. Youhan has the growth habit of III, a light green and mid-sized leaf, hooded and lax-type spikes. The cultivar showed 107 cm of culm length, 641 spikes per $m^2$. The heading date of Youhan was May 1, which is one day later than that of the check cultivar "Yuyeon" in upland, and 2 days earlier than that of Yuyeon in paddy field. The maturation time was similar to check cultivar Yuyeon on June 4 in upland and May 31 in paddy field. In terms of winter hardiness and resistance to lodging and disease, Youhan also performed better than the check cultivar. The average forage dry matter (DM) yield in the regional yield trial was approximately 12.6 ton $ha^{-1}$ and 12.0 ton $ha^{-1}$ in upland and paddy field, respectively, which were 6% and 5% higher than that of the check. The yield also showed 7.3% of crude protein, 26.8% of ADF (acid detergent fiber), 47.8% of NDF (neutral detergent fiber), 67.7% of TDN (total digestible nutrients), and a higher grade of silage quality for the whole-crop barley. Fall sowing cropping of Youhan is recommended only in those areas where the average daily minimum-mean temperatures in January are higher than $-8^{\circ}C$, and it should not be cultivated in mountainous areas of Korea.
