A new six-rowed naked varley variety, Namho, was developed from a crossing berween Nagadehadaka with tolerance to environmental stresses and Sigokku 42 with high yield and resistance to lodging at National Honam Agricultural Experiment Station, RDA in 2002. Its growth habit was winter type (¥²) with greenish leaves, thick culm and six-rowed type, and its heading and maturing date were Apr. 19 and May 25, respectively which were earlier 3 and 4 days, respectively than those of check variety Saessalbori. Also, this variety showed cold tolerance, BaYMV resistance comparing to check variety Saessalbori. In the quality investigation, the grain has the higher ¥â-glucan content, and better cooking quality as water absorption and expansion rate than those of check variety. Its average pearled grain yield in the regional yield trial was 3.86MT/ at double cropping in paddy which was 6% higher than that of check variety. The adaptable area of Namho is warm regions where is more than -7¡É (minimum average temperature on Jan.).
