甜格雷兹甜离粱杂交种2001年从澳大利亚太平洋种子公司引进,经内蒙古赤峰、通辽、包头3个点2002～2004年试验表现优良,又经2004～2005年全国14个点试验,鲜草产量均居第1位,含糖量高,适合作青贮饲料。由于光合效率高,含糖量高,可以制造酒精,作为再生能源,有较高开发价值。1 引进和鉴定情况甜格雷兹甜高粱杂交种,由澳大利亚太平洋种子公司育成,北京德农种业赤峰分公司2001年引进,经过2001～2005年先后在内蒙古和全国各地种植,表现 Sweet Gray sweet sorghum hybrids introduced from the Australian Pacific Seed Company in 2001. The performance of the experiment was excellent from 2002 to 2004 at three points in Chifeng, Tongliao and Baotou in Inner Mongolia. From 2004 to 2005, 14 points of fresh grass yield Ranked No. 1, with high sugar content, suitable for silage. As photosynthetic efficiency, high sugar content, you can create alcohol, as a renewable energy, have a higher development value. 1 Introduction and identification of sweet sorghite sweet sorghum hybrids, bred by the Australian Pacific Seed Company, Beijing branch of the Takon seed industry Chifeng introduced in 2001, after 2001 to 2005 successively in Inner Mongolia and throughout the country, performance
