Abstract

This experiment was carried out to breed an early maturing variety of Italian ryegrass (Lolium multiflorum Lam.) in the Grassland and Forage Crops Division, National Institute of Animal Science, RDA, Cheonan from 2009 to 2011. A new variety, 'Green farm II' is a diploid with green leaves and has a semi-erect growth habit in late autumn and erect growth habit in early spring, respectively. 'Green farm II' was on the $28^{th}$ of April in the heading date as an early-maturing variety. 'Green farm II' was also wider by 0.6 mm in flag leaf width, shorter by 1 cm in flag leaf length and shorter by 1 cm in plant length than those of the control variety, 'Florida 80', respectively. 'Green farm II' was thicker by 0.7 mm in stem thickness and strong in winter hardness. Dry matter (DM) yield (11,452 kg/ha) of 'Green farm II' was similar to that of 'Florida 80'. In vitro dry matter digestibility (IVDMD), total digestible nutrients (TDN), and relative feed value (RFV) of 'Green farm II' were 70.6%, 63.9%, and 114% higher than those of 'Florida 80', respectively. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) of 'Green farm II' were 31.7% and 52.6% which were 3.5% and 6.4% lower than those of 'Florida 80', respectively.

본 시험은 이탈리안 라이그라스 극조생종 품종을 육성하기 위하여 2001년부터 2011년까지 국립축산과학원 초지사료과에서 수행되었다. 이탈리안 라이그라스 신품종 그린팜 2호는 2 배체 작물로 엽은 녹색이며, 월동 전 초형은 반직립형, 봄의 초형은 직립형이다. 그린팜 2호는 4월 28일경에 출수하는 극조생종 품종이다. 또한, 그린팜 2호는 플로리다 80 보다 지엽폭이 0.6 mm 넓고, 지엽의 길이가 1 cm 짧으며, 출수기의 초장은 94 cm로 플로리다 80 보다 1 cm 정도 작다. 줄기 두께는 플로리다 80 보다 0.7 mm로 굵고 이삭 길이는 플로리다 80 보다 2.2 cm 짧았다. 그린팜 2호의 건물수량은 11,452 kg/ha로서 플로리다 80과 대등하였다. 그린팜 2호의 상대적 사료가치는 플로리다 80이 97인데 비해 그린팜 2호는 114로 월등히 높고 in vitro 소화율이 70.6%, 가소화양분총량(TDN)이 63.9%로서 플로리다 80 보다 각각 1.6, 2.8% 높았고, 산성세제불용섬유(ADF)와 중성세제 불용섬유(NDF)는 31.7 및 52.6%로서 플로리다 80 보다 각각 3.5% 및 6.4% 낮았다.
