Abstract (EN): Pollen morphology and quality of 20 olive cultivars grown in Portugal were analysed and multivariate statistical analysis was performed in order to group the cultivars with similar characteristics. The morphology was analysed by scanning electron microscopy and the quality was evaluated through pollen viability and in vitro germination. Pollen grains from the studied cultivars were elliptical, subprolate or prolate spheroidal with an average size (22x20 mu m), 3- zonocolpate for the majority of cultivars but 3-zonocolporate for three of the cultivars studied. Pollen viability varied between 76% ('Verdeal de Tras-os- Montes') to 6% ('Madural') and the germination varied between 65% ('Verdeal de Tras-os-Montes') and 2% ('Conserva de Elvas'). Hierarchical cluster analysis based on all characteristics analysed, showed an organization into three groups composed by cultivars with similar pollen morphometry characteristics and percentages of pollen viability and in vitro germination. Our results indicate that the highest values of olive pollen viability and germination are associated with highest average values of pollen exine reticulum thickness and diameter.
