摘　　要：为选育出质优、高产、抗逆性好的牧草新品种应用于生产,以贵州省独山县采集的野生扁穗雀麦（Bromus carticus）为原始群体,采用混合改良选择法,经1998—2007连续定向培养及试验,选育出牧草新品种,其耐寒性强,适口性好,冬春季青绿,生长速度快,生育天数220d左右,鲜草平均产量78 739kg/hm2,比对照（燕麦）增产23.36%,干草平均产量13 539kg/hm2,比对照（燕麦）增产23.25%。于2009年通过全国草品种审定委员会审定,定名黔南扁穗雀麦（登记号：360）,适宜我国西南地区海拔500～2 300m地区及类似生态区种植。In order to breed new pasture varieties with high quality, high yield, strong stress resistance and apply in production,The wild B.carticus was collected from Dushan County,Qiannan Region of Guizhou Province in 1998,a new strain was bred through the hybrid improved selection method from 1998 to 2007.The new pasture variety was of strong cold endurance,good palatability,dark green in winter and spring,fast growth speed and growth period 220 d.The average fresh and dry pasture yield was 78 739 kg/hm2 and 13 539 kg/hm2 respectively,higher than the control by 23.36% and 23.25%separately.The new variety was approved by the National Forages Variety Appraisal Committee in 2009 and named Bromus carticus cv.Qiannan（Registration number：360）,which was suitable for planting in southwest China with the elevation of 50~2 300 m and similar ecological zones.
