摘　　要：坝莜五号是以冀张莜五号为母本、优良品系753-17-3-1-1-3为父本，采用裸燕麦品种间有性杂交和系谱法选育而成的裸燕麦新品种。2002～2003年参加张家口旱地莜麦品种区域试验，2a平均产量为3199.20k/hm^2，较对照增产9.64％，差异达显著水平。坝莜五号抗旱耐瘠、抗倒抗病（抗黄矮病和秆锈病）、群体结构好、成穗率高、适应性广，是1个适应旱坡地种植、粮草双高产的粮饲兼用型品种。Bayouwuhao is a new naked oat variety bred by crossing between Jizhangyouwuhao （female parent） and high quality line 753-17-3-1-1-3 （male parent） . The average yield of ：2 years regional tests is 3 199.20 kg/hm^2, which increased by 9.64% than CK, and the difference reached significant level. It is resistant to drought, lodging and disease （yellow dwarf and stem rust）, and tolerant to barn. It has good population structure, high spike rate and wideadaptability.
