| 摘要: |
| 为更准确评价谷子品种的丰产稳产和适应性，提高育种效率，采用GGE-biplot双标图软件，对2010—2011年国家谷子区域试验华北夏谷区组中‘豫谷18’等25个参试品种进行丰产稳产和适应性评价。结果表明:1)‘豫谷18’在AEA轴上的垂足最接近正方，丰产性优良；在AEC轴投影距离最短，稳产性突出。2)‘豫谷18’距离理想品种最近，高产稳产性综合表现优于对照品种‘冀谷19’及其他参试品种。3)‘豫谷18’是适应性最广品种，适宜种植区域涵盖华北夏谷区组绝大部分区域。4)与‘冀谷19’比较，‘豫谷18’在华北夏谷大部分区域种植优势明显。综上所述，在华北夏谷区组参试品种中，‘豫谷18’是兼有丰产、稳产和广适应性的理想谷子品种。 |

| Abstract: |
| In this study, the GGE-biplot double plot software was used to analyze the high and stable yield and adaptability of 25 millet varieties such as ‘Yugu 18' in the national millet regional test from 2010 to 2011, and evaluate the adaptability of the target region. The results of two-year regional experiment showed that: 1)the vertical foot of ‘Yugu 18' on AEA axis was the closest to the square, and its high yield was excellent; the projection distance on AEC axis was the shortest, and its stable yield was outstanding. 2)‘Yugu 18' was the closest to the ideal variety, and its comprehensive performance of high and stable yield was better than that of the control variety ‘Jigu 19' and other tested varieties. 3)‘Yugu 18' was the winner of polygon apex, and the most suitable planting area covers most areas of North China summer valley region, which was the most adaptable variety. 4)Compared with the yield of ‘Jigu 19', ‘Yugu 18' had obvious planting advantages in most areas of North China summer valley. It was showed the ideal characteristics of ‘Yugu 18' for high yield, stable yield and wide adaptability in the summer valley region of North China, which provided theoretical basis for the popularization and application of ‘Yugu 18'. |
