Abstract

Protein and carbohydrate contents in polished barley were investigated for two leading varieties in Korea. The contents of crude protein $(total\;nitrogen{\times}5.83)$ were 8.60% for mean. 15.39% for maximum and 6.06% for minimum, and only one third of 22 varieties showed values above mean. the contents of crude protein was significantly correlated with dye binding capacity $(r=0.82^{**})$but insignificantly carbohydrate content. Kyong No.1 (15.39%), Kwan-Chui-Gi (12.42) and Yong-Weul-Yuk-Kak (11.95) can be classified as high protein varieties having appear to be unpopular to farmers. About 50% of barley field was occupied by varieties having protein content above mean, and Kyongnam-Daimaik no.89 (6.76%) a low protein variety, occupied about 8% of barley field, during last decade with little change.
