Abstract EN
Andropogon is a pantropical grass genus comprising 100–120 species and found mainly in the grasslands of Africa and the Americas.
In the new world the genus is represented by approximately sixty (diploids or hexaploids) species grouped in three sections.
The hexaploid condition occurs only in the Americas and the full process of this origin is still uncertain, although cytogenetic analysis coupled with taxonomic evidence have provided strong support for new hypothesis.
Stebbins proposed the first hypothesis suggesting that the origin of polyploidy in species of Andropogon in North America resulted from duplication of the genome of some diploid species, and then by intergeneric crosses with species of a related genus.
Since then, numerous studies were performed to clarify the evolutionary history of the genus in America.
In this paper, we present a review of cytogenetic studies in the American Andropogon species during the last four decades.
