甜荞品种稳定性和试验地点相似性的GGE双标图分析
Stability and testing-site similarity for common buckwheat lines based on GGE-biplot analysis
摘要
Abstract
In order to select the varieties with high and stable yield and widespread adaptability, and to evaluate the testing sites accurately and effectively, GGE - biplot 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 stable yield; Yu 9002 and Xinong 9976, both of which were from Yulin, Shaanxi Province, were similar with each other due to their geographical kinship relationship. The testing sites were divided into three groups, and there were similar test environments in two of them. Dingqiao 1 in all sites showed a universal adaptability, while Yuqiao - 5, Xing-tian 1, Weitian 02 - 198 and Heixiaoqiao possessed special adaptabilities and could only be extended in some areas. GGE - biplot analysis could not only help to select the varieties with high and stable yield, but also show the similarity a-mong different varieties, so it was available for selecting or discarding similar test environments.关键词
