abstract: Abstract Genus Rosa L. is one of most critical taxa within European flora. Majority works is devoted to phylogeny, taxonomy and nomenclature of roses. Investigations of morphology and ecology of roses are still relatively few in number. The aim of this study was to evaluate seed mass and seed yield of six rose species ( Rosa cinnamomea , R. spinosissima , R. rugosa , R. rubiginosa , R. glauca and R. canina ) from populations in Central Russia (Republic of Mordovia). As a result of the study, it
