‘Choyoung’, a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar ‘Choyoung’ has the leaves of medium width, long length and green color and a medium grain of brown color. The heading date of the cultivar ‘Choyoung’ was April 30 which was 2 days earlier than that of check cultivar ‘Shinyoung’. Its tolerance or resistance to cold, wet injury, powdery mildew, and leaf rust was similar to those of the check cultivar. But the resistance to the lodging of cultivar ‘Choyoung’ was stronger than that of the check. The average forage fresh and dry matter yield of cultivar ‘Choyoung’ at milk-ripe stages were 40.5 and 15.7 MT ha-1, respectively, which were similar to those (40.3 and 16.1 MT ha-1) of the check cultivar. The silage quality of ‘Choyoung’ was higher than that of the check cultivar ‘Shinyoung’ in crude protein content (5.9%), while was similar to the check cultivar ‘Shinyoung’ in acid detergent fiber (33.9%), neutral detergent fiber (57.3%), and total digestible nutrients (62.2%). It showed a grain yield of 5.59 MT ha-1, which was 38% higher than that of the check cultivar ‘Shinyoung’ (4.05 MT ha-1). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than -10 ℃.

This experiment was conducted at Suwon, Korea from 2013 to 2015. The objective of this study was to establish the optimum seeding rate, and to clarify the nitrogen fertilizer level for rye seed production in central and north area of Korea. We used Korean rye cultivar ‘Gogu’ for this test. We employed a split-plot design with three replications. The main plots were designed by three seeding levels (3, 5 and 7 kg 10a-1), but other sub-plots were randomly seeded. The plots were treated with three different nitrogen fertilizer levels (3, 6 and 9 kg 10a-1). The percentage of productive tiller, number of grain per spike, fertility rate, 1 liter weight, and 1000-grain weight decreased as seeding rate increased from 3 kg 10a-1 to 7 kg 10a-1, whereas the number of spike per ㎡ increased. Therefore the grain yields of rye had less of an effect by increasing seeding rate. There was an increase in number of spike per ㎡, number of grain per spike, and fertility rate as nitrogen fertilizer level increased from 3 kg 10a-1 to 9 kg 10a-1, but grain yields significantly not affected by the interaction of seeding rate × nitrogen fertilizer levels. However, the best seeding rate and nitrogen fertilizer level for rye seed production were 5 kg and 5∼6 kg 10a-1, respectively, considering seed and fertilizer reduction and the prevention of pollution by excess fertilization.

'Dakyeong' (Avena sativa L.), a winter oats for forage use, was developed by the breeding team at National Institute of Crop Science, RDA in 2016. It was derived from a cross between ‘CI7505’(IT133304) and ‘Swan’(IT197920). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Iksan and Jeonju, respectively. After preliminary and advanced yield test for 2 years, ‘SO2004009-B-B-10-8-3-9’, designated as a line name of ‘Gwiri91’, were subsequently evaluated for earliness and forage yield during 3 years in four parts such as Jeju (upland), Yesan (upland), Iksan (upland), and Jeonju (paddy), from 2014 to 2016, and finally named as ‘Dakyeong’. Cultivar ‘Dakyong’ has leaves of dark green color, thick diameter culm and long grain of brown color. Over 3 years, the heading date of ‘Dakyeong’ was about 5 days earlier than that of check cultivar ‘Samhan’ (April 30 and May 5, respectively), and their average forage dry matter yield harvested at milk-ripe stage was higher 12% (15.7 tone ha-1) than 14.0 tone ha-1 of check cultivar. Cultivar ‘Dakyeong’ was lower than the check cultivar ‘Samhan’ in terms of the protein content (6.1% and 7.0%, respectively) and total digestible nutrients (62.1%, and 62.5%, respectively), while the TDN yield was more than the check (7.79 tone ha-1 and 7.64 tone ha-1, respectively). Fall sowing cropping of ‘Dakyeong’ is recommended only in areas where average daily minimum mean temperatures in January are higher than -6°C, and it should not be cultivated in mountain areas, where frost damage is likely to occur.

Oats (Avena sativa L.), which are known as one of the forage crops of Korea, have good livestock palatability and are popular to cattle farmers because of their high dry matter. However, the cultivation of double cropping in the rice field was reluctant due to the late maturing for farmers to plant rice continuously. 'Hi-early', a winter oats for forage use, was developed by the breeding team at National Institute of Crop Science, RDA in 2016. It was derived from a cross between ‘517A2-121’(IT133383) and ‘CI7604’ (IT133379). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon, Iksan and Jeonju, respectively. After preliminary and advance yield test for 2 years, ‘SO2004015-B-B-23-1-3-7’, designated as a line name of ‘Gwiri92’, were subsequently evaluated for earliness and forage yield during 3 years in four parts such as Jeju (upland), Yesan (upland), Iksan (upland), and Jeonju (paddy), from 2014 to 2016, and finally named as ‘Hi-early’. Cultivar ‘Hi-early’ has the characteristics of medium leaves of green color, thick diameter culm, and medium grain of brown color. Over 3 years, the heading date of ‘Hi-early’ was about 9 days earlier than that of check cultivar ‘Samhan’ (April 26 and May 5, respectively). Average forage fresh yield of ‘Hi-early’ harvested at milk-ripe stage was similar to check cultivar (40.2 tone ha-1 and 40.0 tone ha-1, respectively), and dry matter yield also was similar to check cultivar (14.2 tone ha-1 and 14.0 tone ha-1, respectively). Cultivar ‘Hi-early’ was lower than the check cultivar ‘Samhan’ in terms of the protein content (6.2% and 7.0%, respectively) and total digestible nutrients (61.0%, and 62.5%, respectively), while the TDN yield was more than the check (7.91 tone ha-1 and 7.64 tone ha-1, respectively). Fall sowing cropping of ‘Hi-early’ is recommended only in areas where average daily minimum mean temperatures in January are higher than -6°C, and it should not be cultivated in mountain areas, where frost damage is likely to occur.

‘Saeyoung’, a winter triticale (X Triticosecale Wittmack) for forage, was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2012. The cultivar ‘Saeyoung’ has narrow and long leaves of light green color, middle size and thin culm, and a medium grain of brown color. The heading date and yellow ripe stage of ‘Saeyoung’ was May 3 and May 27, which were similar to check cultivar ‘Shinyoung’, respectively. ‘Saeyoung’ showed a little stronger in cold tolerance and a little weaker in resistance to lodging than the check, and wet injury, powdery mildew, and leaf rust were similar to those of the check cultivar. The forage fresh and dry matter yields of ‘Saeyoung’ at milk-ripe stages were 47.2 and 15.6 MT ha-1, respectively, which was 9% and 4% higher than those of the check. The crude protein content of ‘Saeyoung’ was 0.4% lower than 6.8% of the check, while was higher than the check cultivar ‘Shinyoung’ in neutral detergent fiber, acid detergent fiber. Total digestible nutrients of ‘Saeyoung’ was also 3% lower than 62.8% of the check cultivar. It showed grain yield of 4.1 MT ha-1, which was 11% higher than that of the check. ‘Saeyoung’ is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than -10 ℃.

A new naked oat cultivar, ‘Jungmo2005’(Avena nuda L.), was developed for food and forage use by National Institute of Crop Science, RDA in 2010. It was derived from a cross between F1[‘Early80’/‘Gwiri33’] and F1[‘Early80’/‘Gwiri23’]. ‘Early80’, a covered oats, has early heading and high yielding, while ‘Gwiri23’ of covered type and ‘Gwiri33’ of naked type has early heading with large-size grain. ‘Jungmo2005’ has the characteristics of narrow and long leaves of pale green color, middle diameter culm of yellow color and medium grain of whitish yellow color. Cultivar ‘Jungmo2005’ had 2 days earlier heading date (May 9) than the check cultivar ‘Seonyang’ (May 11) in field condition. The ‘Jungmo2005’ showed better winter hardiness than that of the check cultivar, and similar to the check cultivar in respect to lodging resistance. The ‘Jungmo2005’ had 105 cm of culm length, 21.5 cm of spike length, 658 spikes per m2, 82 grains per spike, 23.3 g of 1,000-grain weight, and 622 g of test weight. The grain yield of ‘Jungmo2005’ was averaged 3.38 MT ha-1, which was 6% higher than that of the check. Average forage fresh and dry matter yield of ‘Jungmo2005’ harvested at milk-ripe stage were 44.8 and 12.6 tone ha-1, respectively, compared with 47.5 and 12.5 tone ha-1 of the check. The protein content of the ‘Jungmo2005’ was similar to the check (7.6% and 7.5%, respectively), while ADF (28.6%) and NDF (51.5%) were lower than the check (31.4% and 57.0%, respectively). TDN content and RFV were higher than those of the check (66.3%, 120.3 and 64.1, 105.2, respectively). ‘Jungmo2005’ is recommended for fall sowing cropping only in the south area where daily minimum mean temperatures are averaged higher than -4 ℃ in January, and it should not be cultivated in mountain areas, where frost damages is likely to occur. The areas would do better only to sow in spring season.

‘Shinseong’, a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar ‘Shinseong’ was selected from the cross RONDO/2*ERIZO_11//KISSA_4/3/ ASNO/ARDI_3//ERIZO_7 by CIMMYT (Mexico) in 1998. Subsequent generations were handled in pedigree selection programs at Mexico from 1999 to 2004, and a line ‘CTSS98Y00019S-0MXI-B-3-3-5’ was selected for earliness and good agronomic characteristics. After preliminary and advance yield testing in Korea for 3 years, the line was designated ‘Iksan47’. The line was subsequently evaluated for earliness and forage yield in seven locations, Jeju, Iksan, Cheongwon, Yesan, Gangjin, Daegu, and Jinju from 2013 to 2015 and was finally named ‘Shinseong’. Cultivar ‘Shinseong’ has the characteristics of light green leaves, yellow culm and spike, and a medium grain of brown color. The heading date of cultivar ‘Shinseong’ was April 24 which was 3 days earlier than that of check cultivar ‘Shinyoung’. The tolerance or resistance to lodging, wet injury, powdery mildew, and leaf rust of ‘Shinseong’ were similar to those of the check cultivar. The average forage dry matter yield of cultivar ‘Shinseong’ at milk-ripe stages was 15 MT ha－1, which was 3% lower than that (15.5 MT ha－1) of the check cultivar ‘Shinyoung’. The silage quality of ‘Shinseong’ (6.7%) was higher than that of the check cultivar ‘Shinyoung’ (5.9%) in crude protein content, while was similar to the check cultivar ‘Shinyoung’ in acid detergent fiber (34.6%), neutral detergent fiber (58.6%), and total digestible nutrients (61.6%). It showed grain yield of 7.2 MT ha－1 which was 25% higher than that of the check cultivar ‘Shinyoung’ (5.8 MT ha－1). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than －10℃.
