Analysis of apricot germplasm from the European ecogeographical group.

During 1993-96, 18 morphological, phenological and fruit quality traits of 55 apricot (Prunus armeniaca) cultivars, including the most important clones grown in Spain, France and Italy, were evaluated at Valencia using principal component analysis. Given that the studied material was made up of commercial cultivars, the range of variation observed was narrower than expected. Variation was observed for traits related to phenology and fruit quality. The only correlation observed between morphology and phenology was that of flowering and budbreak season being correlated with internode length. Harvest season was negatively correlated with acidity. Native cultivars from Spain and Tunisia were a good source of early ripening but lacked fruit size and postharvest handling qualities, respectively.
