Festulolium braunii 교잡종의 재배특성, 사료가치 및 수량성 = Dry Matter Yields of the Hybrids Associated with Festulolium braunii

다국어 초록 (Multilingual Abstract)

This experiment was carried out in order to examine the winterhardiness, heading date, fresh and dry matter yeild of Festulolium braunii, a hybrid of Festuca pratensis and Lolium multiflorum, which is newly introduced in Korea. This experiment was performed at National Livestock Research Institute in Suwon and Namwon from September 2004 to July 2005. The results are as follows. “Fleurial”, “Boxer”, and “Perun” showed stronger winterhardiness than “Hwasan 101”, which is one of the strongest in the winterhardiness hybrids. Therefore, we do not see there is any problem in winterhardiness when these hybrids are cultivated in Korea. The hybrids are turned out to be mid and late maturing hybrid. The average heading dates of the three hybrids were May 25 in Namwon and May 27 in Suwon. These dates are lower(1~3 days) than that of Hwasan 101. They showed 91~96 ㎝ in leaf length at 1st cutting times which are comparatively long. This experiment also disclosed that their lodging and regrowth are strong and excellent. We also found out that there are significant difference between regions and hybrids in the total fresh yield per ha. The average fresh yield of Suwon was 83,222 ㎏/㏊ and that of Namwon was 69,139 ㎏/㏊. We could not see any difference in the dry matter yield affected by region, however, there were significant difference in hybrids(p＜0.05). The crude protein contents of the three hybrids indicated very high figures. the crude protein cotents of Perun, Fleurial and Boxer are 18.0%, 17.4% and 16.7% respectively. However the ADF (Acid Detergent Fiber) shows 28.1~29.2% which is less contents than 33.2% of Hwasan 101. We found out from this experiment that these three hybrids have excellent feed quality because the NDF (Neutral Detergent Fiber) is decreased by 7~3.8% comparing that the NDF of Hwasan 101 is 58.3%. Also each hybrids contains more crude fat by 1%, a little more chemical composition and less ash contents. Thus we can learn that chemical composition contents of these hybrids are also fittable.
