Research Project: Seed Increase, Evaluation, and Phytosanitary Assessment of Quarantined and Tropically-adapted Genetic Resources

Location: Tropical Crops and Germplasm Research

Project Number: 6090-21000-056-00-D
Project Type: In-House Appropriated

Start Date: Feb 14, 2018
End Date: Feb 13, 2023

Objective:
Objective 1. Efficiently and effectively regenerate under quarantine, and under tropical, equatorial conditions, genetic resources of grain, legume, and vegetable crops to maintain their safety, genetic integrity, health, and viability. Following seed increase and/or quarantine assessment, release seed supplies of those genetic resources to other USDA National Plant Germplasm System (NPGS) genebanks for maintenance and distribution. Objective 2. Characterize and evaluate for priority traits the genetic resources of grain, legume, and, vegetable crops regenerated for seed increase and/or quarantine assessment. Record and disseminate evaluation and characterization data via Germplasm Resources Information Network (GRIN)-Global and other data sources.

Approach:
Select and treat seed for freedom of signs and symptoms of pathogens; conduct annual disease surveys; inspect and verify status of plants (PPQ); grow quarantined and/or photoperiod-sensitive crops, report new diseases, maintain low pest levels, bag heads prior to anthesis; identify diseases and take regulatory action; record key descriptor information for entry into Germplasm Resources Information Network (GRIN), harvest seed and examine for disease symptoms; and return seed to National Plant Germplasm System (NPGS).
