The size of Germplasm Collections has become an important limitation for theirr use in plant breeding programs. To overcome this limitation the Core Collection concept has been proposed. A Core Collection consists of a set of accessions selected to represent the genetic diversity of the base collection with minimum repetitiveness. This insures the conservation of maximum genetic variation, allowing rapid evaluation of germplasm and better access to the base collection. The brazilian germplasm Collection of Cassava is the largest national collection, and contains strategic genetic variation for the development of breeding programs worldwide. It consists of approximately 3350 accessions conserved in 7 regional Active Germplasm Banks. To develop the Core Collection a hierarchical stratification similar to that proposed by Cordeiro et al (1995) was used. Two key criteria were used for the stratification of the accessions: category and origin. According to category the accessions were classified as landraces or breeding materials. Within the landraces strutum, accessions were classified according to ecogeographical origin using the Geographic Information System. The selection of the members of the Core, was done trying to represent the genetic variability within each ecogeographic zone, incorporating the knowledge and experience of the curators. This Core Collection will be a logical and efficient starting point for studying the Base Collection using biotechnological tools. |
