Abstract

This experiment was carried out to study the effect of difference in cold-tolerance and growth characteristics of variety on forage productivity of Italian ryegrass(IRG) in middle region of Korea from 2017 to 2018. Cold-tolerance of IRG was significant different between varieties(p<0.05). Overwinter rate of domestic variety of IRG was higher than that of foreign variety(p<0.05). Among early-maturing varieties, overwinter rate of Kowinearly was highest as 68% that was 33% higher than that of Florida 80. Among middle-maturing varieties, overwinter rate of Kowinmaster was highest as 70% that was 28% higher than that of Tam 90. DM yield of IRG was significant different between varieties(p<0.05). Among early-maturing varieties, DM yield of Kowinearly and Greenfarm 2 was about 3 to 3.5 ton/ha more than that of Florida 80. Among middle-maturing varieties, DM yield of Kowinmaster was about 2ton/ha more than that of winter-hawk or Tam 90. There is a direct correlation between forage productivity and cold-tolerance of IRG variety(p<0.01). These results suggested that choice of early- or middle-maturing variety with cold-tolerant is more important for increasing the forage productivity of IRG If harvesting for roughage have to be finished in the middle ten days of May in middle region of Korea.

본 연구는 이탈리안 라이그라스 품종별 내한성 및 생육특성의 변화와 그에 따른 생산성 변화요인을 분석하기 위하여 2017년부터 2018년까지 우리나라 중부지역인 충남 천안에서 수행되었다. 이탈리안 라이그라스의 월동율은 품종 간에 차이가 있었으며(p<0.01), 외국품종보다 국내품종이 대부분 월동이 잘되었다. 조생종에서는 코윈어리의 월동율이 68%로 가장 높았고, Florida 80의 월동율이 35%로 가장 낮았으며, 중생종에서는 코윈마스터의 월동율이 70%로 가장 높았고, 외국품종인 Tam 90이 42%로 가장 낮았다(p<0.05). 외국품종 중에서는 Winter-hawk가 57% 월동하여 다른 외국 품종보다 월동율이 높았다. 건물수량은 품종 간 차이가 많았다(p<0.05). 조생종 중에서는 내한성이 강한 국내품종인 그린팜 2호와 코윈어리가 외국품종인 Florida 80보다 건물수량이 약 3~3.5톤/ha 많았다. 중생종 중에서는 내한성이 강한 국내품종인 코윈마스터가 외국품종인 Winter-hawk나 Tam 90보다 건물수량이 약 2톤/ha 많았다(p<0.05). 이탈리안 라이그라스의 내한성은 건물생산성과 고도의 정의상관이 있었다(p<0.01). 우리나라 중부지역에서 이탈리안 라이그라스를 5월 중순에 수확을 완료해야 한다면, 내한성이 강한 국내 육성 조생 또는 중생품종을 선택하여 재배하는 것이 양질 조사료 생산성 향상에 유리할 것으로 사료된다.
