Abstract

‘Punghan’ (Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2008. It was derived from a cross between ‘Beltsville 61-150 (IT133501)’ and F1 between ‘Sikyonggwiri’ and ‘PA202-210’. A oat cultivar from USA, ‘Beltsville 61-150’, has a high cold tolerance, while the F1 between ‘Sikyonggwiri’ and ‘PA202-210’ has early heading and high yielding with large-size grain. Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon and Yeoncheon, respectively. A line, ‘SO99013-B-YB-31’, was selected for earliness and good agronomic characteristics and designated as a line name of ‘Gwiri 60’. The line ‘Gwiri 60’ was subsequently evaluated for winter hardiness, earliness, and forage yield in five locations, Yesan, Cheongwon, Iksan, Kimjae, and Jeju, from 2006 to 2008 and finally named as ‘Punghan’. Over 3 years, the average forage dry matter yield of ‘Punghan’ harvested at milk-ripe stage was 14.5 ton ha-1, compared with 13.6 ton ha-1 of check cultivar ‘Samhan’. ‘Punghan’ is about 2 days earlier in heading date than check cultivar. ‘Punghan’ is adapted primarily for winter planting use in the mid- southern regions of Korean peninsula.
