Comparative Study on Production Performance of Forage Triticale and Italian Ryegrass in Hunan Province
In order to screen forage germplasm suitable for planting in Hunan province,the agronomic traits and lodging resistance were compared and analyzed by field experiment in 5 experimental sites(Xiang-bei Experimental Station,Xiangdong Experimental Station,Xiangxi Experimental Station,Xiangnan Experimental Station and Xiangzhong Experimental Station)with three forage materials of forage triticale(Zhongsi 3297)and Italian ryegrass(Muyao and Tegao)as materials.The results showed that the plant height,stem diameter and hay yield of Zhongsi 3297 were the highest among the germplasm,lodging resis-tance was the best.The tiller number and fresh yield of Tegao were the highest,and the leaf number of Muyao was the largest.The plant height,stem diameter,tiller number,fresh and hay yield were the high-est at the Xiangxi Experimental Station among the sites,and the leaf number was the largest at the Xiang-bei Experimental Station.The stem diameter and hay yield of Zhongsi 3297 were the highest at the Xiang-zhong Experimental Station,and the tiller number and fresh yield were the highest at the Xiangxi Experi-mental Station,and the leaf number of Muyao was the largest at the Xiangbei Experimental Station.The correlation analysis showed that Zhongsi 3297 triticale had the best production performance,and was the most suitable for planting in Hunan Provine.
