This study was conducted to select suitable rice cultivars for high-quality rice production in silage barley-rice double cropping in Honam plain area by National Institute of Crop Science from 2008 to 2009. Heading dates of all tested cultivars were before the safe heading limit(Aug. 31). Rice yield was superior in "Keunseom", "Hanareum", "Hanmaeum", "Onnuri", "Hopum", "Juan 1", "Dongjin 1", and was little in "Daepyeong", "Hwasin", "Malgeumi", "Chilbo", "Nampyeong", "Hopyeong". Protein content was high in "Hanareum", "Keunseom", "Chilbo", "Nampyeong", and was low in "Hanmaeum", "Dami", "Sindongjin", "Pyeongan", "Samgwang". And head rice ratio was high in "Malgeumi", "Hwanggeumnuri", "Samgwang", and was low in "Keunseom", "Hanareum", "Dami", "Hanmaeum", "Hwasin". In consideration of all the factors, in conclusion, proper cultivars for silage barley-rice double cropping are "Onnuri", "Hwanggeumnuri", "Hopum", "Dongjin 1", "Juan 1".
