Abstract
Samhan (Avena sativa L.), a winter forage oat was released by the National Crop Experiment Station (NCES) in2001. Samhan was selected from the cross Early 80/CI 7518. CI 7518 is a winter oat line that was obtained from UnitedStates Department of Agriculture (USDA). Subsequent generations followed by the cross were handled in bulk and pedigree selec-Suwon, and was designated as a line name of Gwiri 37. Samhan was subsequently evaluated for winter hardiness and forageyield in Suwon, Unbong and Iksan from 2000 to 2001. Over 2 years, the average forage yield of Samhan harvested at May 10was 7.1 ton ha1, compared with 2.76 ton ha1 for Ol and 2.96 ton ha1 for Swan. Samhan is about 6 days later than Olfor heading date. Samhan is adapted primarily for winter planting for forage use in the central regions of Republic of Korea.
