Background: Today, old citrus fruit varieties with traits suited to a market more attentive to a limited territorial distribution of certain species and the preservation of biodiversity are being promoted. One of these is the Portugal orange. The name 'Portugal' disappeared from the writings on citrus fruit growing in the first half of the last century, systematically replaced by the name 'Common Blond'. Methods: One hundred fruits of ‘Portugal’ and ‘Common Blond’ oranges come from two varietal collections found in Sicily. Physico-chemical and sensory analyses were carried out to evaluate the qualitative characteristics of both varieties and to confirm or confute the previous hypothesis. Results: These analyses confirm that from the point of view of fruit quality, there are no significant differences between 'Portugal' and 'Common Blond' oranges. The differences found can be attributed to the different growing environments, i.e. cultural practices, microclimate, fertilization, etc. Conclusion: Furthermore, the historical information provided also supports the hypothesis that the 'Portugal' orange simply changed its name to 'Common Blond', even though there were numerous bud variations that led to the selection of different clones.

Abstract

Background: Today, old citrus fruit varieties with traits suited to a market more attentive to a limited territorial distribution of certain species and the preservation of biodiversity are being promoted. One of these is the Portugal orange. The name 'Portugal' disappeared from the writings on citrus fruit growing in the first half of the last century, systematically replaced by the name 'Common Blond'. Methods: One hundred fruits of ‘Portugal’ and ‘Common Blond’ oranges come from two varietal collections found in Sicily. Physico-chemical and sensory analyses were carried out to evaluate the qualitative characteristics of both varieties and to confirm or confute the previous hypothesis. Results: These analyses confirm that from the point of view of fruit quality, there are no significant differences between 'Portugal' and 'Common Blond' oranges. The differences found can be attributed to the different growing environments, i.e. cultural practices, microclimate, fertilization, etc. Conclusion: Furthermore, the historical information provided also supports the hypothesis that the 'Portugal' orange simply changed its name to 'Common Blond', even though there were numerous bud variations that led to the selection of different clones.
