Abstract: Commercial sugarcane cultivars and wild species have a high ploidy level allied to a complex genome and usual chromosomal instability. There are few studies related to the standardization of cytogenetic techniques in sugarcane. This work tested the efficiency of three antimitotics (colchicine, 8-hydroxyquinoline, and trifuralin) at different concentrations on the quality of metaphases spreads from a commercial sugarcane cultivar (IAC911099-Saccharum spp.) and a wild sugarcane accession (Krakatau-S. spontaneum). Although all three antimitotics were efficient for obtaining metaphases, 8-hydroxyquinoline was the most efficient for both IAC911099 and Krakatau. The chromosome number of these two genotypes was inferred. The variation in chromosome number was 2n = 90–112 for IAC911099, with a statistical modal of 2n = 112 chromosomes while the variation in chromosome number was 2n = 90–129 chromosome with a statistical modal of 2n = 128 chromosomes for Krakatau (S. spontaneum). © 2015, Society for Sugar Research & Promotion.
