A New Cold Tolerant, High Forage and Grain Yielding Winter Oat Cultivar 'Samban'

Abstract

'Samhan' (Avena sativa L.), a winter forage oat was released by the National Crop Experiment Station (NCES) in 2001. 'Samhan' was selected from the cross 'Early 80'/'I7518'. 'CI 7518' is a winter oat line that was obtained from United States Department of Agriculture (USDA). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon and Yeoncheon. 'S0 9500 1-B-GB-4' was selected for winter hardiness and forage yield in 1998 at Suwon, and was designated as a line name of '$\hat{O}Gwiri\;37$' . 'Sarnhan' was subsequently evaluated for winter hardiness and forage yield in Suwon, Unbong and Iksan from 2000 to 200 1. Over 2 years , the average forage yield of 'Sarnhan' harvested at May 10 was 7.11 ton ha- 1, compared with 2.76 ton ha- I for '0 1' and 2.96 ton ha- 1 for 'Swan' . 'Samhan' is about 6 days later than '0 1' for heading date. 'Samhan' is adapted primarily for winter planting for forage use in the central regions of Republic of Korea.
