Abstract

'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.

트리티케일 품종 '광영'은 2018년에 농촌진흥청 국립식량과학원에서 육성되었다. '광영'은 폭이 넓고 길이가 중간 정도인 녹색잎과 황갈색이면서 중간 길이의 이삭, 크기가 크고 황갈색인 종실을 가졌다. '광영'은 표준품종인 '신영'과 비교할 때 출수기가 전국 평균 4월 22일로 같았고, 내한성·내도복성·내병성도 같은 수준이었으며, 지상부의 잎 비율이 27.5 %로 '신영'의 21.2 % 보다 높았다. 생초수량은 ha당 평균 50.0톤, 건물수량은 평균 17.6톤으로 '신영'의 각각 47.0톤, 17.1톤에 비해 높았다. 품질특성으로 '광영'은 '신영'에 비해 조단백질 함량이 5.3 %로 다소 낮았고, NDF 및 ADF 함량도 각각 58.2 %와 34.9 %로 다소 높았으며, TDN 함량은 61.3 %로 약간 낮았으나, 사일리지 등급은 1등급이었다. '광영'은 종실 수량이 ha당 6.03톤을 보였다.
