Abstract: In order to explore the genetic relationship of buckwheat germplasm resources and find beneficial genes of buckwheat germplasm resources, 9 main biological traits of 100 accessions of buckwheat germplasm resources were investigated through principal component analysis, and the scatter plots were drawn based on the first 6 principal components (PC) and the clustering analysis was carried out based on the genetic coefficients. The first 6 principal components of the 100 accessions of buckwheat germplasm resources accounted for 88.76%. 10 accessions of buckwheat germplasm resources with excellent traits were selected based on the comprehensive score of cultivar traits. The genetic similarity coefficients of all resources were from 0.03 to 22.63 in the dendrogram. 100 accessions of buckwheat germplasm resources were classified into 3 clusters at the level of 5.32 genetic coefficients, cluster Ⅰ included 37 accessions, cluster Ⅱ included 24 accessions, and cluster Ⅲ included 39 accessions. Buckwheat germplasm resources in cluster Ⅱ had higher plant height, more weighty seed yield, and good yielding ability. ZNQ098, ZNQ086, ZNQ048, ZNQ093, ZNQ082 had the best traits based on principal component analysis, the scatter plot and cluster analysis. They could be used as ideal breeding materials.
