Research Project: Plant Germplasm and Technology Exchange Between the U.S. and China

Location: Tropical Crops and Germplasm Research

2010 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.


3.Progress Report

The objectives of the agreement correspond with objective 1 of the parent project (Evaluate tropical/sub-tropical fruit production systems and germplasm for broad agro-environmental adaptation, high yield and productivity, and ability to produce fruits of superior quality).

A visit by Southwest Forestry University scientists was made to the National Clonal Germplasm Repository for Fruit and Nut Crops at David, California. Exchange of information was mainly directed to the adaptability of grape and date germplasm to Chinese environments.

This project was monitored through visits to laboratories and by communications with collaborators by phone, email or during their visits.
