Research Project: Plant Germplasm and Technology Exchange between the USDA-ARS and Guangxi Subtropical Crops Research Institute

Location: Tropical Crops and Germplasm Research

2012 Annual Report

1a. Objectives (from AD-416):
To conduct cooperative research related to the evaluation, characterization, identification, and preservation of cultivated and indigenous plant genetic resources and to exchange plant germplasm that is of mutual interest.

1b. Approach (from AD-416):
ARS and the Cooperator will exchange propagating material (true seed, budwood, hereinafter referred to as Breeding Material), of tropical and subtropical crops following recommended phytosanitary procedures, including quarantine. Breeding Material will be increased in the greenhouse or field for testing and evaluation for specific traits (e.g. disease resistance, enhanced yield and fruit quality) of interest or as commercial cultivars. DNA fingerprinting 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/subtropical fruit production systems and germplasm for broad agroenvironmental adaptation, high yield and productivity, and ability to produce fruits of superior quality. An accession of longan seedlings collected from a wild population near Vietnam at the Guangxi Station is flowering in our field. The fruits will be the first bearing from the group and will be evaluated in October. A planned visit to the Guangxi Subtropical Crops Research Institute was delayed due to lack of funding.
