- Abstract
'Jopung' (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 2009. It was derived from an original cross between the F1 hybrid of 'Early80' and 'PA202-210-S' and 'Walken' in 1999. Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon and Yeoncheon, respectively. A line, 'SO99006-B-YB-29-Y1', was selected for earliness and good agronomic characteristics and designated as a line name of 'Gwiri65'. The line 'Gwiri65' was subsequently evaluated for earliness and forage yield in four different locations, Yesan, Iksan, Kimjae, and Jeju, from 2007 to 2009 and finally named as 'Jopung'. Over 3 years, the average forage dry matter yield of cultivar 'Jopung' harvested at milk-ripe stage was 17.3 MT ha-1, compared with 13.6 MT ha-1 of check cultivar 'Swan'. The silage quality of 'Jopung' was superior to the check cultivar 'Swan' in crude protein content, and was similar to the check cultivar in percent total digestible nutrients (TDN). Cultivar 'Jopung' is suitable primarily for winter planting in the southern regions of Korean peninsula.
