Abstract

This experiment was conducted to evaluate the agronomic characteristics and forage production of Italian ryegrass cultivars at three locations (Gurae, Sungju and Cheonan) from 2013 to 2014. The experiment employed a randomized complete block design with three replications. The seven cultivars used in this experiment were 'Korwinearly', 'Florida80', 'YounbongI', 'YounbongII', 'YounbongIII', 'KeimyungI' and 'KeimyungII' varieties. Italian ryegrass varieties were seeded on October 4 at Gurae, October 8 at Seongju and October 3 at Cheonan in 2013. The Italian ryegrass varieties were harvested on April 26 at Gurae and Seongju, and on April 24 at Cheonan in 2014. Although the seven cultivars had resistance to foliar diseases and insects and high winter survival, they has little lodging resistance. The heading dates for 'Younbong I', 'Younbong II' and 'Keimyung I' were earlier than for other varieties at the three locations. Dry matter (DM) content and plant height in the early maturing cultivars were higher than in other cultivars at the three locations. The fresh and DM yields of the early maturing cultivars were also higher than others at the three locations. The results of this experiment indicate that the heading date for early maturing cultivars is earlier, and the plant height is higher than for other cultivars. Early maturing cultivars had higher DM content as well as fresh and DM yields of Italian ryegrass. Therefore, early maturing cultivars should be recommended as high-yield forage in double-cropping systems because of their superior production of forage and early heading date.

본 시험은 2013년부터 2014년까지 전국 3개 지역 (전남 구례, 경북 상주 및 충남 천안)에서 이탈리안 라이그라스 품종의 생육특성과 사초생산성을 평가하였다. 시험설계는 품종을 처리로 하여 7개 품종을 3반복의 난괴법 배치로 하였다. 품종은 '코윈어리', '플로리다 80', '연봉1호', '연봉2호', '연봉3호', '계명1호', 및 '계명2호' 공시하였다. 이탈리안 라이그라스의 파종의 경우 전남 구례는 2013년 10월 4일, 경북 상주는 10월 8일, 충남 천안은 10월 3일 파종하였다. 한편 수확시기는 품종의 평균 출수기로 전남 구례와 경북 상주는 2014년 4월 26일에 수확하였으며, 충남 천안은 4월 24일에 수확하였다. 공시한 7품종은 내병성, 내충성 및 내한성은 품종간에 차이가 없었으나 내도복성은 공시품 종 모두 약하였다. 전국 3개 지역에서 '연봉1호', '연봉2호' 및 '계명1호'의 출수기가 다른 품종보다 빨랐다. 출수기가 빠른 조생종 이탈리안 라이그라스는 건물률이 높고 초장도 다른 품종보다 높았다. 또한 조생종은 생초수량과 건물수량도 다른 품종보다 많았다. 본 시험결과를 볼 때 숙기가 빠른 품종은 다른 품종에 비하여 초장이 높고, 건물률, 생초수량 및 건물수량이 많은 것으로 평가되었다. 따라서 숙기가 빠르고 사초 생산성이 우수한 조생종 이탈리안 라이그라스가 2모작체계에 유리할 것으로 판단된다.
