‘Gwangyoung’, a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2018. The cultivar ‘Gwangyoung’ has leaves of wide width, medium length, and green color, and spikes of medium length and yellowish-brown color, and a large grain of yellowish-brown color. The heading date of the cultivar ‘Gwangyoung’ was April 22 which was similar to check cultivar ‘Shinyoung’. Its tolerance or resistance to cold, lodging, wet injury powdery mildew, and leaf rust were also similar to those of the check cultivar. The leaf blade ratio of ‘Gwangyoung’ (27.5%) was higher than that of ‘Shinyoung’ (21.2%). The average forage fresh and dry matter yield of cultivar ‘Gwangyoung’ at milk-ripe stages were 50.0 and 17.6 MT ha-1, respectively, which were higher than those (47.7 and 17.1 MT ha-1) of the check cultivar. The silage quality of ‘Gwangyoung’ was lower than that of the check cultivar ‘Shinyoung’ in crude protein content (5.3%) and total digestible nutrients (61.3%), while was higher than the check cultivar in neutral detergent fiber (58.2%) and acid detergent fiber (34.9%). ‘Gwangyoung’ showed the silage of 1 grade and a grain yield of 6.03 MT ha-1.
