| Abstract: |
| Factor and cluster analysis were carried out on the 12 agronomic characters of 53 Tartary Buckwheat resources from Shaanxi Province.Six main factors(their cumulative contribution achieved 80.17%) were chosen as comprehensive indexes by the factor analysis,and then systematic cluster analysis was conducted.The result indicated that while the genetic distance reached 7.46,Tartary Buckwheat accessions can be divided into five categories of the width grain category,the lodging resistance category,the grain-used category,the big grain and non-lodging resistance category and the thick-peel category,which is of benefit to selecting excellent tartary buckwheat resources and improving yield and characters of Tartary Buckwheat. |
