BIODIVERSITY OF SICILIAN FRUIT TREES: STUDIES ON PLUMS

Abstract

The Sicilian territory contains a wide reserve of biodiversity of fruit tree species that, over a period of several centuries, have found there propitious pedoclimatic conditions for their establishment, and genetic diversification. The indigenous germplasm characterized Sicilian agriculture until less than one century ago but, after the diffusion of new cultivars originating from genetic improvement programs, a great part of this germplasm was replaced and now these important resources are at high risk of genetic erosion. Recently, public interest in the safeguarding of biodiversity and the development of a new interest in genetic resources and their scientific, economic and cultural importance, inspired several political actions aimed at the valorisation and conservation of this material. The present study, funded by the Sicilian government, aims to improve knowledge concerning Sicilian plum germplasm, which accounts for a great number of the accessions on the Island, through an action of characterization that includes various steps: biometric, qualitative and nutraceutical. The study was preliminarily carried out on 26 accessions as a preliminary study to facilitate the development of an efficient methodology prior to extending it to other accessions localized in the Sicilian territory.
