From 1992, a phenological survey of the olive groves located from the fertile valley of the Guadalquivir River up to the Subbética Mountain range. The studied points are distributed in zones of different altitude of the south of the province of Cordoba.In the different points we found several varieties of Olea europaea such us Picual, Hojiblanca and Picudo.
The phenology key followed to identify the different phenophases was the proposal by Maillard (1975).

Nowadays 13 points are surveyed. They are located on the transept from Cordoba city passing through the Guadalquivir Valley and mid-altitude lands up to the Subbetica Mountains.
The obtained phenological results allow interpreting the olive pollen curve registered in the city of Cordoba. These data can explain the contribution of pollen from olive populations located far away from the city.
