摘　　要：在滇南雨养条件下,对4个非洲狗尾草(Setaria sphacelata)品种进行区域性品比试验。结果表明:参试各品种适应性强,均未染病,存活率和越冬率都在98.61%以上。种植第1年TPRC010的干草产量最高,为27.68t·hm^(-2)。用灰色关联法进行综合评价,TPRC001表现最优,TPRC010次之。The comparison experiment of four Setaria sphacelata varieties in southern subtropical areas of Yunnan was carried out in 2006 for the purpose of establishing pasture with high production and quality through selecting proper forage materials.Results showed that all tested Setaria sphacelata varieties were adapted to the climate condition of Yunnan,and could be used for pasture establishment in the southern subtropical zone.In the first year,the dry matter yield of TPRC010 was the highest （27.68 t · hm-2）among all tested varieties.Comprehensive evaluation of forage using grey correlation method showed that the most promising species was TPRC001,and the second one was TPRC010.
