Abstract
본 시험은 남부지방에 벼 대체 여름 사료작물인 옥수수를 파종하여 조사료를 생산하는데 논 재배에서 적응성 및 생산성이 우수한 품종을 선발할 목적으로 2007년부터 2008년까지 2년간에 걸쳐 전라남도 농업기술원에서 수행하였다. 국내육성 2품종과 도입품종 4품종 등 6품종 을 시험한 결과 광평옥 품종이 간장이 198cm 로 다른 품종들보다 크고 경직경이 굵으며 내습성 및 후기 녹체성이 좋고 우수한 특성을 보였으며 수량 측면에서도 생초수량은 ha당 생초 수량은 38.5톤이며 건물수량은 14톤이고 TDN 수량은 9.6톤으로 P3156, P3394에 비해 최고로 높은 편이지만 이와 같은 수량은 밭 재배에서의 수량에는 다소 미치지 못하는 것으로 나타났다. This experiment was carried out to know adaptability and forage production and quality of corn hybrid for silage at paddy field from 2007 to 2008 at JullaNamdo Agricultural Research and Extension Services (ARES). Among agronomic characteristics, 'Kwangpyongok' hybrid was somewhat strong for waterlogging and good stay green, lodging, disease and insect resistance. The fresh yield and total digestible nutrients (TDN) of 'Kwangpyongok' hybrid were the highest among corn hybrids. Dry yield of 'Kwangpyongok' hybrid was increased to 50.5%, 13.6% due to waterlogging tolerance than those 'P3156' and 'P32P75' hybrids, respectively. The result of this study indicated that 'Kwangpyongok' hybrid could be recommended as having good characters according to production, waterlogging tolerance, stay green at paddy field in southern region of Korea.
