Abstract
Crop production in the United States, including fruit crops, has been dependent on the introduction of genetic stocks.
Plant introduction, begun by the early colonists, has evolved into a national program which includes the long term maintenance of genetic stocks and the addition of new material through plant exploration or exchanges to fill gaps in our genetic resources.
The maintenance of fruit stocks has not been as well organized as with other crops and a system of repositories is being developed to protect these resources.
These collections will include a broad genetic base of cultivars and species which the repositories will be responsible for evaluating and distributing.
Of the many fruit and nut genera in the U.S., Pyrus, Rubus, Vaccinium, Corylus, Ribes, and Fragaria are maintained at the Corvallis, Oregon repository.
Prunus, Vitis and Juglans will be maintained at Davis, California.
Other genera such as Citrus and Malus will be located at other repositories.
Many useful characteristics have already been identified in existing collections including disease and insect resistance, climatic and soil adaptation, growth characteristics, as well as quality factors and yield, but more work is needed.
