摘　　要：为选育适应藏东南三江峡谷农林交错带种植的冬青稞品种,2013—2015年在藏东南三江峡谷农林交错带实施了7个点、12个品种的秋播冬青稞品种区域试验。结果表明:在12个参试品种中,云裸1号产量最高,折合产量353.0 kg/667 m^2,较对照迪青3号增产20.8%,表现为增产优势突出,但对环境和肥水条件反应异常敏感;冬青8号、冬青17号、玖格和冬青11号4个品种均比对照增产;冬青16号、长芒裸大麦和冬青15号3个品种产量与对照迪青3号持平(±3%),但长芒裸大麦适宜种植范围较窄;勾芒米大麦、洋大麦和米大麦3个品种,平均产量均比对照迪青3号减产,尤以米大麦减幅最大。In order to breed and select winter hulless barley varieties suitable for cultivation in forest-agriculture ecotones of the canyon in Eastern Qinghai-Tibetan Plateau, regional trials were carried out to evaluate the performance of 12 new autumn-sown winter hull-less barley varieties（or lines） at 7 sites in forest-agriculture ecotones of the canyon in Eastern Qinghai-Tibetan Plateau during2013—2015. As a result, the yield of the variety Yunluo 1 reached 353.0 kg/667 m^2, the highest among the 12 tested varieties, which was 20.8% higher than that of the control variety Diqing 3. While demonstrating prominent production advantage, Yunluo 1 was very sensitive to environmental and fertilization conditions. The average yields of four varieties（Dongqing 8, Dongqing 17, Jiuge, and Dongqing 11） were higher than that of the control（Diqing 3）. The average yields of three varieties（Dongqing 16, long awn naked barley, and Dongqing 15） were similar to that of the control（±3%）, but the long awn naked barley had a narrower range of suitable cultivation areas. On the other hand, three varieties（the hook Mangmi barley, Yang barley, and rice barley） showed a reduction in average yield compared with the control, with rice barley having the largest drop in yield.
