Start Date: Apr 16, 2008
End Date: Feb 25, 2013
Plant exploration expeditions will be taken in North Africa, Central Asia, Northern Europe for pome fruit and in China, Japan, Russia, Korea, Central and South America for berry crops. Plants from these areas will fill current gaps. Collecting trips will occur in collaboration with foreign scientist and quarantine officials. Horticultural and botanical experts in taxonomy will be consulted to verify the identity of accessions. Primary collections of woody plants will be maintained in field collections. Primary collections of herbacious perennial genera will be maintained in a screenhouse and repropagated. Duplicate plants will be maintained on site. Available plant materials will be distributed for research purposes. Backup hazelnut collection will be maintained in Parlier, California. Backup of small fruit, mint, and hop will occur on site. Tropical or sub tropical accessions will be protected from temperature extremes. Core collections will be propagated in vitro and in cryogenic storage at NCGRP, Fort Collins. Primary collections will be tested for pathogens and infected accessions will be subjected to therapy procedures to develop pathogen free replacments. Microsatellite fingerprinting sets will evaluate genetic diversity and determine clonal identity of blueberries, strawberries, hazelnuts, and pears. Clonal collections will be evaluated for high priority phenotypic characters including phenology, plant habit, fruit characters, and incidence of naturally occurring disease. Molecular and phenotypic information will be loaded to the public GRIN database.
