| 为了更准确有效地筛选高产、稳产、适应性强的品种和对试验地点的评价，采用GGE双标图
对国家区域试验中第八轮甜荞区域试验数据进行分析。结果显示：定荞1号、黑小荞、榆荞-
5为产量高、稳定性好的品种；甜荞品种榆9002和西农9976较相似，均来自于陕西榆林，具
有
地理上的亲缘关系；试验地点相对集中分为三组，第二组和第三组中有相似的试点；定荞1
号处于所有试点之中，具有普遍适应性，而榆荞-5、兴甜1号、威甜02-198和黑小荞具有特
殊的适应性，在局部地区有推广价值。利用GGE双标图准确筛选出优良品种，同时显示了品
种间的相似程度；根据GGE双标图可对试点，尤其是相似试点进行选择和取舍。 |
| 英文摘要: |
| In order to select the varieties with high and stable yield and widespread adapt
ability, and to evaluate the testing sites accurately and effectively, GGE-biplo
t method was adopted to
analyze the data from the 8th national regional trials for common buckwheat. The
results showed
that Dingqiao 1, Heixiaoqiao and Yuqiao-5 were the varieties with high and stabl
e yield; Yu 9002
and Xinong 9976, both of which were from Yulin, Shaanxi Province, were similar w
ith each other
due to their geographical kinship relationship. The testing sites were divided i
nto three groups, and
there were similar test environments in two of them. Dingqiao 1 in all sites sho
wed a universal
adaptability, while Yuqiao-5, Xingtian 1, Weitian 02-198 and Heixiaoqiao possess
ed special
adaptabilities and could only be extended in some areas. GGE-biplot analysis cou
ld not only help
to select the varieties with high and stable yield, but also show the similarity
among different
varieties, so it was available for selecting or discarding similar test environm
ents. |
