This study was carried out to investigate the adaptability of major whole crop silage rice varities to the wet seeding in the new reclaimed land during 2012 to 2013. Seeding stand ratios were 48% for Nokyang and Suweon 552, and 40 ~ 42% for Mogwoo, Mogyang and Suweon544. The heading dates were August 26 ~ 27 for Nokyang and Mogyang, September 1 ~ 5 for Suweon 552 and Suweon544, and September 15 for Mogwoo. Number of panicles per square meter varied 278 ~ 333 depending on the tested varieties. Lodging occurred in Suweon552 slightly, and did not occur in the other varieties. Dry matter yield per ha was 15.8 ~ 16.8 tons for Mogwoo and Suweon552, and 13.1 ~ 14.3 tons for Suweon 544, Mogyang and Nokyang. Crude protein content of varieties was 4.5 ~ 6.4%; ADF, 27.1 ~ 30.1%; NDF, 49.2 ~ 53.9%; TDN, 65.1 ~ 67.4%. These results suggest that Mogwoo and Suweon 552 are the whole crop silage rice varieties suitable for wet seeding in the new reclaimed tidal land.
