‘Yeongwoo’, a mid-late flowering, high dry matter yielding rice (Oryza sativa L.) cultivar with high feed value and multiple disease-insect resistance, was developed for whole crop silage (WCS) use. It was derived from a cross between a high biomass and brown planthopper (Bph) resistant ‘SR25848-C99-1-2-1’ and high yielding Tong-il type, ‘Yongmun’ which had diseases resistance. This cultivar had about 117 days growth period from seeding to heading, 99 cm culm length, 26 cm panicle length, 11 panicles per hill, 125 spikelets per panicle, and 1,000-grain weight of 23.6 g as brown rice in the central plain region, Suwon. This wide and long leafy WCS rice variety was weak to cold stresses, similarly to ‘Nokyang’ but was resistant to lodging in the field, strong to viviparous germination, and good under low temperature germination. In addition, ‘Yeongwoo’ was resistant to leaf and neck blast, bacterial blight (race K1, K2, K3, K3a), rice stripe virus, Bph, and small Bph. Its average dry matter yield for three years reached 20.0 MT/ha, 32% higher than that of ‘Nokyang’. This cultivar had 5.3% crude protein and 71.7% total digestible nutrients, which was slightly lower than that of ‘Nokyang’. In the Korean peninsula, ‘Yeongwoo’ grew well in the central and southern plain and was could be harvested between 15 to 30 days after heading to improve the feeding value and digestion rate of livestock (Grant No. 6800).

The 'Misomi' is a rice variety derived from a cross between ‘Sobi’ which has adaptability of low fertilizer cultivation and SR21110 (Ilpum/Jinbu19) by the rice breeding team at National Institute of Crop Science, RDA in 2013. The heading date of ‘Misomi’ is August 14 and six days later than check variety, ‘Hwaseong’. It has 83 cm of culm length and 121 spikelets per panicle. It showed weaker cold tolerance than that of ‘Hwaseong’ during exposed to cold stress. ‘Misomi’ showed resistance to blast disease, K1, K2 and K3 race of bacterial blight and stripe virus, but susceptibility to K3a race, other viruses and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and short grain shape. It has low protein content (6.2%) and similar amylose content (19.4%) to that of ‘Hwaseong’. ‘Misomi’ showed better palatability index of cooked rice than that of ‘Hwaseong’. Particulary, ‘Misomi’ showed excellent processing adaptability than ‘Chucheong’ and ‘Hwaseong’ on palatability index of cold and aseptic cooked rice. Its milled rice recovery rate is similar to those of ‘Hwaseong’. However, whole grain rate of milled rice is higher than that of ‘Hwaseong’. 'Misomi' has 5.68 MT/ha of milled rice productivity in ordinary cultivation, which was 12% higher than that of ‘Hwaseong’. 'Misomi' could be adaptable to the middle plain area and Midwest coast area in Korea (Grant No. 5635).

‘Jungmo1038', a mid-late maturing, high dry matter yielding rice (Oryza sativa L.) cultivar with glabrous leaf and hull, was developed for whole crop silage (WCS) use. It was derived from a cross between ‘SR24592-HB2319’ with high biomass, smooth leaf and hull and good germinability in low temperature and new plant type (NPT), ‘IR73165-B-6-1-1‘ which had low tillering trait, large panicle, dark green leaf, thick and sturdy stem and vigorous root system. This cultivar had about 125 days growth period from seeding to heading, 99cm culm length, 20cm panicle length, 13 panicles per hill, 119 spikelets per panicle and 1,000-grain weight of 23.3 g as brown rice in central plain region, Suwon. This hairless WCS rice variety was weak to cold stresses similar to ‘Nokyang’ but was resistant to lodging in the field, strong to viviparous germination and good to low temperature germination. In addition, ‘Jungmo1038’ was resistant to leaf and neck blast but susceptible to bacterial blight, rice stripe virus and brown planthopper. Its average dry matter yield for three years reached 17.2 MT/ha, 21% higher than that of ‘Nokyang’. This glabrous cultivar had 6.6% crude protein and 62.4% total digestible nutrients a little low compared to ‘Nokyang’. In Korea peninsular, 'Jungmo1038' grows well in central and southern plain and is good to harvest between 15 to 30 days after heading to improve its feeding value and digestion rate of livestock(Grant No. 5634).
