TO select the most suitable crop and variety of forage for nutrient quality at the southern part of Korea, the crop of wheat, barley and rye were grown from Oct. 1999 to June 2000. Paldanghomil variety of rye crop was shown to have the highest chemical components in comparison to other varieties of crops used in this experiment. It showed relatively high content of crude protein and in vitro dry matter digestibility (IVDMD) and low content of NDF, ADF, cellulose and lignin. Therefore, it was concluded that paldanghomil of rye crop was the most suitable variety with high weight and high nutrient quality for forage in the southern part of Korea. The heritabilities of all nutrient quality characters were estimated to be high.
