| Abstract: |
| 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. |
