Project Number: 5402-21000-011-02
Project Type: Specific C/A

Start Date: Sep 02, 2003
End Date: Jun 01, 2007

Objective:
To determine appropriate population size and pollination strategies to capture and maintain genetic diversity as seeds of wild-species accessions of Malus, Pyrus, Prunus and Vitis.

Approach:
The work will involve hiring a post doctorial associate to perform statistical tests using genetic marker data assembled by PGPRU. The post doc will perform tests to estimate the genetic diversity within and among wild-collected accessions and hybridization rates among plants in the orchard. Based on these data, minimum effective population size and crossing strategies to maintain the level of captured diversity will be determined. Scenarios of population size and pollination strategies will assess risks of genetic erosion.
