Abstract: The methods of research on relationship of rose germplasm resources included morphology, palynology, cytology, biochemical analysis and DNA molecular markers. With constant innovation and improvement of DNA molecular marker, it was becoming more and more important in the study of rose relationship .The analysis of relationship can provide reference for the parent selection in breeding of distant hybridization that was an important way for rose germplasm innovation. This paper reviewed the research progress on the genetic relationship of rose germplasm resources. Therefore, it can provide basis for exploring the origin, evolution, classification, genetic diversity analysis, and marker-assisted seletion of rose germplasm resources.

Key words:  Rose, germplasm resources, genetic relationship
