Research Project: **Location:
                            Tropical Crops and Germplasm Research** Project Number: 6090-21000-060-000-D
                        
                        Project Type: In-House Appropriated Start Date: Feb 14, 2023
                        
                        End Date: Feb 13, 2028 **Objective:**
                        
                        1. Maintain the safety, genetic integrity, health, and viability of priority genetic resources through seed increases and release of quarantined NPGS accessions of grain genetic resources.

2. Generate phenotypic evaluation and morphological characterization data for genetic resources cultivated for regeneration and/or release from quarantine and incorporate those data into the GRIN-Global information management system. **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).
