摘　　要：湖北省是中国主要的冬大麦(Hordeum vulgare L.)产区。分析了2006—2020年湖北省大麦产量变化特点和育种进展,发现每穗粒数的增加是产量提高的主要因素,而逆境是制约稳产的关键因子,从而提出未来改良湖北省大麦产量仍需以提高穗粒数为主,同时要提高品种对低温、干旱和湿渍等逆境的耐抗性。Hubei province is the main winter barley producers area in China. The characteristics of barley yield change and breeding progress in Hubei province from 2006 to 2020 were analyzed. It was found that grains per spike was the major factor for increasing yield,and environmental stresses was the the major factor for decreasing yield,so increasing grains per spike and enhancing muliple resistances for low temperature,drought and humidity was the key of barley yield improvement in future.
