Plant Germplasm and Technology Exchange between the U.S. and China
Tropical Crops and Germplasm Research
2011 Annual Report
1a.Objectives (from AD-416)
To establish research collaboration in plant germplasm and technology exchange that is mutually beneficial in the evaluation, characterization, identification and preservation of cultivated and indigenous plant genetic resources.
1b.Approach (from AD-416)
ARS and the Cooperator will exchange propagating material (true seed, budwood)of tropical and subtropical crops following recommended phytosanitary procedures, including quarantine. Materials will be increased in the greenhouse or field for future testing and evaluation for specific traits(e.g. disease resistance, enhanced yield and fruit quality)of interest or as commercial cultivars. DNA fingerprinting work will be conducted to assess genetic diversity. GRIN training will be provided if deemed necessary by both parties.
The objectives of the agreement correspond with objective 1 of the parent project: Evaluate tropical/sub-tropical fruit production systems and germplasm for broad agroenvironmental adaptation, high yield and productivity, and ability to produce fruits of superior quality.
Germplasm of Garcinia mangostana and Garcinia dulcis was sent to collaborators at Southwest Forestry University from the USDA-ARS Tropical Agriculture Research Station, Mayaguez, Puerto Rico and 15 accessions of citrus and wild relatives from the USDA-ARS National Clonal Germplasm Repository for Fruit and Nut Crops at Riverside, California.
This project was monitored through visits to laboratories and by communications with collaborators by phone and email.
