Interpretive Summary:

Technical Abstract: The work described here was the conclusion of an exploratory project that examined the feasibility of using in situ conservation sites as complementary additions to the existing ex situ collections of the U.S. Dept. of Agriculture, Agricultural Research Service, National Plant Germplasm System (NPGS). We assess genetic variation using morphologic and molecular (simple sequence repeats) characters in populations of two narrowly distributed endemics: Caloosa grape (Vitis shuttleworthii House) and sweet mountain grape (Vitis monticola Buckl.) occurring in limited areas in Florida and Texas, respectively. We identified four in situ conservation sites for Caloosa grape and three for sweet mountain grape using a strategy based on morphologic and molecular data, population size and integrity, and landholder commitment. The explicit link between the in situ conserved populations and their utilization would be the NPGS crop curator, who would monitor populations and collect propagules and budwood for distribution to researchers and breeders for evalutaion.
