| 运用AMMI模型对2009—2011年第三轮国家青稞品种区域试验中10个品种在8个试点上的稳定性、试验试点辨别力以及品种的特殊适应性等进行分析。结果表明：① 在参试环境范围内,0376(Hiploy/沈村二棱)属高产稳产型；9642产量最高,稳定性一般，具有区域普遍适应性；9640产量较高，但稳定性最差，具有特殊适应性。② 试点对于品种的分辨力不同，青海西海镇试点的分辨力最强，对于品种具有较好的鉴别力，是鉴定青稞品种稳定性比较理想的地方。③ AMMI模型较好地拟合了本试验数据，但利用AMMI模型分析应结合AMMI双标图和稳定性参数准确地进行判定。 |

| In this research, the AMMI model was used to analyze the stability, discriminative power and adaptability on ten highland barley varieties on trial at eight regional stations during 2009—2011. The results showed that within the trial, variety 0376 (Hiploy/Shencunerleng) gained a high and stable yield; variety 9642 showed the highest yield, good stability, and wide adaptability; variety 9640 exhibited a high yield but low stability and specific adaptability. Additionally, different stations were indicated to have different discriminative powers. The station at West Town in Qinghai may be good for trail by having the strongest discriminative power on varieties. In conclusion, the AMMI model fits well with the experimental data. However, AMMI biplot and stability parameters should be combined for accurate prediction. |
