Abstract (EN): The great importance of distinguishing and identifying olive cultivars has been recognized since Roman times. Several classification schemes have been tried based on botanic, ecological, morphological, commercial, and agronomical characteristics. Presently there are a great number of different olive cultivars showing a diversity of morphological and physiological characteristics that result in quite different qualities and uses. However, the olive quality cannot be directly measured, and several indirect measurements, for example fruit and endocarp features, must be correlated with the olive quality and cultivar. This chapter shows that from morphological features of olives (fruit and endocarp) and olive trees (including trees, branches, leaves and flowers) coupled with chemometric multivariate classification techniques, classes of olives from different cultivars are naturally observed. Mixing morphological features from olive fruit and endocarp, classification rules with potential to be applied in the quality control of olives and, consequently, in the Denomination of Protected Origin (DOP) assessment can be developed. Also, it is observed that olive trees can be characterized using classification rules based on leaf and flower features. © 2010 Copyright
