Advances in phylogeny and evolution studies of Roegneria

Roegneria Koch is the largest genus in the Triticeae Species groups. Within this genus there are many good resources, for example, the genes related to highyield, pestresistant and stress tolerance, and they are necessary for wheat and other grain crops. However, many issues are still in debate in Roegneria, such as the classification system, evolution status and evolutionary relationship with other related genera. This essay aimed to give better understanding of the phylogenetic profiles in Roegneria systematically. According to research data on the establishment of Roegneria, evolution status, genome composition and differentiation, an overview was given. With the development of the molecular marker techniques, the method for phylogenetic studies on Roegneria would become more effective, which combined with molecular systematics, cytology and traditional morphological techniques.
