Phylogenetic analysis of Saccharum s.l. (Poaceae; Andropogoneae), with emphasis on the circumscription of the South American species (original) (raw)

Polyploidy and reticulate evolution complicate the phylogenetic relationships of the genus Saccharum, which includes economically significant species like sugarcane. This study evaluates the phylogenetic relationships among Saccharum s.l., Erianthus, and Tripidium, concluding that Saccharum is polyphyletic but Erianthus lacks strong evidence for segregation. Additionally, the research clarifies the taxonomic boundaries of South American species and identifies natural hybrids, providing insights beneficial for sugarcane breeding.
