Nuclear Collection

It is a collection, which represents the minimum of repetition, the genetic diversity of cultivated species and their related species. The nuclear collection concept is applied in germplasm collections with 10-15% the size of the original collection, representing 70-80% of the variability available on the genetic species of interest and relatives wild. The rest of the collection remains in reserve as a source of genes for future use. Although a nuclear collection will never replace a base collection or even collection of work very specialized structure and size are key factors to stimulate the user to use the germplasm more often than that maintained the traditional active collection.
