The collections are maintained as living trees; two trees for each accession. The latest integrated crop management techniques are used, relying on natural predators, non-pesticide controls and pest and disease modelling to optimise spraying.
Genetic analysis techniques are used to monitor trees through repropagation and characterise the diversity held within the collection. This will improve the utility of the material for breeding, as well as aid the management of the collection.
In recent years we have almost completed a full cycle of repropagation. New collections of pear and apple have been established and we are currently establishing new plum and cherry collections. These new plantings should secure the collection for the future.
