Conservation of Prunus avium genetic resources in France

Abstract : Prunus avium is one the most important Noble Hardwood Species in Europe. With its high-value wood, this species is of great economic interest. It can be found in nearly all the french territory except the mediterranean area and above 1000 m. But its genetic resources are seriously endangered by intensive forest management, hybridization with domestic or foreign species, unknown origin of imported seeds plantations. Prunus avium is one of the first species chosen by France for the implementation of the National Genetic Conservation Programme. The French strategy is based on a regional conservation. Two main different ways are used to preserve the genetic basis. On a first hand, an in-situ conservation network is in project in areas where natural stands are big enough to hold a large genetic basis. On a second hand, for regions without large stands, different single trees have been harvested and their progenies sown in nurseries. The plants produced will be planted in pseudo in situ forest conservation stands. Cemagref wish to explore genetic diversity by morphological and biometric measurings, and also biochemical markers. After this work, the different european collections could be compared.
