Phenotypic diversity in blackthorn (Prunus spinosa L.) populations and opportunities for valorisation

In the last period, a multitude of researches have directed their attention to the immense biodiversity existing in Prunus spinosa species, either for the valorisation of fruits, rich in biologically active components, or for the valorisation of some individuals for improvement or ornamental purposes.
The present paper aimed to study the existing genetic diversity in blackthorn populations from spontaneous flora of Oltenia region (Romania), to identify valuable individuals and to propose their exploitation.
A characterization of the plant and physical-chemical analysis of fruits were carried out.
Determining the physical and chemical characteristics of fruits is a stage that precedes the establishment of their edible mass and an important step towards the qualitative and quantitative assessment of production volume and tracing the directions for the valorization of fruits.
As a result of the observations made, it was proven that there is a high variability between blackthorn genotypes, regarding the fruit characteristics, while some genotypes could be important from an orchard crop and food value point of view.
