With 2 figures and 1 tableAbstract The purpose of this study was to evaluate the genetic diversity in 19 snow mold resistant clones and four creeping bentgrass ( Agrostis stolonifera L . ) commercial cultivars. The phylogenetic relatedness of creeping bentgrass and three other bentgrass species: colonial bentgrass ( A. capillaris ), dryland bentgrass ( A. castellana ), and velvet bentgrass ( A. canina ) was elucidated. A total of 199 polymorphic Amplified Fragment Length Polymorphism markers were amplified from six selected Eco RI /Mse I primer combinations. Both, the principal coordinate analysis and the dendrogram obtained by cluster analysis distinguished three groups to be consistent with genomic compositions of these bentgrass species. Cluster analysis of genetic similarity estimates revealed a high level of diversity among bentgrass species ranging from 0.43 to 0.90 with an average of 0.55. In 19 disease‐resistant creeping bentgrass clones, genetic similarities ranged from 0.55 to 0.90 with an average of 0.61.
