Abstract

A new tall fescue variety (Festuca arundinacea Schreb.) named 'Greenmaster2ho' was developed by the National Institute of Animal Science, Rural Development Administration, in Cheonan, Korea from 2010 to 2014. For the synthetic seed production of this new variety, 5 superior clones were selected and polycrossed: 09XFa02, 09XFa03, 09XFa11, 09XFa13, and 09XFa14. The agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan from 2010 onward, and regional trials were conducted in Cheonan, Hoengseong, Jeju, and Jinju from 2012 to 2014. Greenmaster2ho showed resistance to disease, persistence, and regrowth ability that were all enhanced when compared with Fawn. At 15,119 kg/ha, the dry matter (DM) yield of Greenmaster2ho was 29% higher than that of Fawn, but the nutritive value of both varieties as forage was similar. This study aimed to make a contribution to the vitalization of the Korean grassland industry by developing a new tall fescue variety with excellent environmental adaptability.

본 시험은 엔도파이트 프리 톨 페스큐 신품종을 개발하기 위하여 2008년부터 2014년까지 농촌진흥청 국립축산과 학원 초지사료과에서 수행되었다. 톨 페스큐 신품종 '그린마스터2호'는 6배체 품종으로서 잎은 녹색이며, 출수기가 5월 16일경으로서 대비품종인 'Fawn' 보다 5일 늦은 중생품종이고, 출수기에 초장은 82.5 cm 정도이다. 지역적응시험 4개 지역평균 건물수량은 '그린마스터2호'가 15.1톤/ha로서 대비품종인 'Fawn' 보다 29% 많았으며, 지역별로는 4개 지역 모두에서 'Fawn' 보다 생산성이 우수하였다. '그린마 스터2호'의 사료가치는 조단백질(CP) 함량이 13.9%, 건물소화율(IVDMD)이 69.9%, 가소화양분총량(TDN)이 63.8%, 중성세제불용섬유(NDF)가 59.4%, 산성세제불용섬유(ADF) 는 33.5%로서 Fawn과 대등하였다. '그린마스터2호'는 엔도파이트에 감염되지 않는 품종이면서 'Fawn' 보다 국내 기후환경 적응성과 영속성이 우수하여 초지조성에 알맞은 품종으로서 우리나라 전국에서 재배 가능하다.
