 Abstract
`Taehan` (Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crops, NICS, RDA in 2012. It was derived from a cross between `Malgwiri` and `CI8015`. Subsequent generations were handled in bulk and pedigree selection programs at Suwon and Yeoncheon, respectively. After 2 years of preliminary and advanced yield tests, `SO00020B-YB-15-5-9-4-3`, designated as `Gwiri78`, were subsequently evaluated for earliness and forage yield during 3 years in four regions such as Yesan, Iksan-1 (Paddy), Iksan-2 (upland), and Jeju from 2010 to 2012, and finally named `Taehan`. Over 3 years, the heading date of `Taehan` was about 6 days earlier than that of the check cultivar `Samhan` (May 8 and May 14, respectively), and their average forage dry matter yield harvested at the milk-ripe stage was 14.5 tone , compared with 14.1 tone for the check cultivar. The cultivar `Taehan` was lower than that of the check cultivar `Samhan` in terms of protein content (6.3% and 7.7%, respectively) and total digestible nutrients (60.7%, and 62.1%, respectively). The TDN yield was more than that of the check cultivar (9.1 tone and 8.0 tone , respectively). Fall cropping of `Taehan` is recommended only in areas where average daily minimum mean temperatures in January are > , and it should not be cultivated in mountainous areas, where frost damage is likely to occur.
