摘　　要：为指导安单3号大面积生产,为山区玉米品种选育提供参考,应用2001—2006年贵州中西部组玉米区试材料,采取常规和高稳系数法对安单3号的丰产性和稳定性进行了分析评价。结果表明:安单3号在不同区域和不同年度间产量差异均不显著,在同组试验中产量的变异系数、标准差和环境参数均较小,稳定系数最高,表现出对各种生态类型和生产环境有较好的适应性和稳产性。The adaptability and stable yield capacity of Andan 3 were evaluated by using the conventional analysis method, and high and stable coefficient method based on the data of Guizhou regional tests during 2001-2006 to provide a reference for guiding its large acreage production and maize breeding. The results showed that there was no significant difference in its yield between different regions and between different years, the variance coefficient, standard deviation and environment parameter of its yield were lower than those of other varieties and its stable coefficient was the highest in the same group, which indicates that Andan 3 is of the better adaptability and stable yield capacity in different ecological and production environments of Guizhou orovince.
