영문 초록

‘Gowoo’, a mid-late flowering, high yielding rice (Oryza sativa L.) cultivar with glabrous leaf and hull and resistant to multiplediseases and insects, was developed for forage use. It was developed for use as a whole crop silage obtained from a cross between ‘Kusahonami’with high biomass, smooth leaf and hull, lodging resistance and Japonica high yielding line ‘Iksan514,’ which showed resistance to bacterialblight (BB) (race K1, K2, K3) and rice stripe virus (RSV). In the central plain region of Suwon, ‘Gowoo’ cultivar exhibited a growth periodof approximately 120 days from seeding to heading, 111 cm culm length, 22 cm panicle length, 12 panicles per hill, 140 spikelets per panicle,and 1,000-grain weight of 23.4 g as brown rice. This hairless forage rice variety was weak in response to cold stresses, similar to ‘Nokyang’. However, it was resistant to lodging in the field and showed a strong response to viviparous germination. In addition, ‘Gowoo’ was resistantto leaf and neck blast, BB, RSV, and small brown planthopper. Its average dry matter yield for three years reached 18.2 MT/ha, which was21% higher than that of ‘Nokyang’. This glabrous cultivar had 5.3% crude protein and 68.2% total digestible nutrients, a little low comparedto ‘ Nokyang’. In Korea p eninsular, ‘ Gowoo’ g rows well in c entral a nd s outhern plain and is g ood to h arvest b etween 1 5 to 3 0 days afterheading to improve its feeding value and digestion rate of livestock (Grant No. 8681).
