Abstract
A detailed morphological analysis of Coffea arabica pachytene chromosomes is presented for the first time. The pachytene chromomeric patterns revealed that there occurs some structural similarities in about 54% of the 22 bivalents. This fact is supported by two secondary associations observed, one of them involving one nucleolar bivalent. Based on these results, and other evidences from literature, it is suggested that C. arabica is a segmental alIopolyploid with genetically controlled chromosome pairingKeywords
