Conteúdo: | The pollen morphology of 12 population samles from three Amazonian landraces (Putumayo - three samples, Solimoes - two samles, Para - three samples), one Central America landrace (Utilis - one sample) and two Amazonian hybrid populations (Belem - one sample, Yurimaguas - two samples) of B. gasipaes (pejibaye or peach palm) was studied. The pollen grains, measured from the polar view, differed mainly in size with racial averages varying from 59.6um to 73.3 um. The samples had significantly larger pollen grains than the other samples. Exine morphology is typically semisectate, with a columellar infratectum. Numerous perforations are visible in the tectum, except for the Utilis landrace population, which had very few perforations. Phenotic relationships are close for the Amazonian landraces and distant for all others.
