摘　　要：为探索异源八倍体小黑麦黔中 3号、黔中 5号在道真县不同海拔高度、不同生态环境和栽培管理条件下的适应性、丰产性和稳产性 ,特引种试验、示范。从试验结果看出 :黔中 3号、黔中 5号的分蘖力、再生能力、抗逆性、抗病性、丰产稳产性、适应性和营养品质均优于小麦绵阳 2 6 ,尤以在海拔 80 0 m以上地区产量比小麦绵阳 2 6增产 19.88%～ 2 3.0 7% ,增产极显著。并随海拔的增高 ,产量增幅呈递增趋势 ,其中以海拔110 0 m的试点产量最突出 ,比小麦绵阳 2 6增产 2 4 3.9%～ 2 94 .95 %。Qianzhong 3 and Qianzhong 5, two new allooctoploid triticale varieties were introduced to determine the adaptability, high yield ability and steady yield ability under the different elevation, ecological environment and cultivated conditions in Daozheng county. The results showed that two varieties were superior to Mianyang 26(CK) in tillering ability, regenerated ability, resistance, steady high yield ability, adaptability and nutrient quality. The yield of allooctopliod triticale varieties at an elevation above 800m was 19.88%～ 23.07% higher than that of Mianyang 26 and the yield increase trends with the elevation rising. The yield of two new allooctopliod triticale varieties was 243.9%～294.95% higher than that of Mianyang 26 at the elevation of 1100 m.
