Abstract: The objective of this work was to determine the chromosome number and nuclear DNA content of five species of the genus Amaranthus, which commonly occur in Brazil. Metaphase chromosomes were obtained through the flame drying technique and stained with 5% Giemsa, and DNA content was determined by flow cytometry. 2n=32 chromosomes were observed in A. hybridus and 2n=34 in the other studied species, indicating the occurrence of descendant dysploidy. The nuclear DNA content ranged from 1.28 to 1.79 pg, and A. deflexus had the highest value.
