Location: Nat'l Clonal Germplasm Rep - Tree Fruit & Nut Crops & Grapes
2021 Annual Report
Accomplishments
1. Crop germplasm distribution. ARS scientists and staff in Davis, California, shipped crop germplasm, including 2,925 items to 200 stakeholders (six international and 194 domestic) to research and education entities that require genetic diversity or genetic standards. The germplasm collections were assembled and managed by ARS scientists to be made available to scientists, especially geneticists and breeders who develop new cultivars to address the needs of growers and consumers. Most germplasm requests were shipped in late winter/early spring as three to five cuttings per accession. Leaves, pollen, and fruit were also sent as requested.
