Research Project: Management of Tropical/subtropical Plant Genetic Resources and Associated Information

Location: Tropical Crops and Germplasm Research

Project Number: 6635-21000-051-00
Project Type: Appropriated

Start Date: Apr 11, 2013
End Date: Apr 10, 2018

Objective:
1. Efficiently and effectively conserve, back-up, regenerate, and evaluate tropical and subtropical fruit, bamboo, and cacao genetic resources and distribute them and associated information worldwide. 2. Aided by genetic marker information, strategically fill gaps in the current coverage of tropical and subtropoical fruit, bamboo, and cacao germplasm collections through international exchanges. 3. In collaboration with other NPGS genebanks and research projects, develop novel genetic marker systems for tropical and subtropical fruit, bamboo, and cacao genetic resources. Apply those markers to more efficiently and effectively manage genetic resources and facilitate their use in breeding and research projects.

Approach:
Plant genetic resources will be efficiently and effectively conserved, backed-up, regenerated, evaluated, and distributed free of diseases. This will be carried out by implementing latest technologies available for field, lab, and greenhouse plant labeling, by maintaining on and off-site backups of critically important germplasm, by field evaluating for important horticultural traits and by indexing/eliminating plant diseases in stock to be distributed. All information associated with plant genetic resources including passport, characterization, and evaluation data will be incorporated into the publicly available GRIN database. The development of molecular marker tools for systematic characterization of the site's plant germplasm is a collaborative effort with other USDA-ARS laboratories. Marker tools developed in collaboration will aid in the identification of redundancies, discrepancies, and genetic gaps in the collections. In addition, the marker work will complement morphological characterization and stakeholder community input in the development of guidelines to follow for prioritization of future plant introductions.
