Research Project:
SEED INCREASE AND PHYTOSANITARY ASSESSMENT OF QUARANTINED AND TROPICALLY-ADAPTED GENETIC RESOURCES
Location: Tropical Agriculture Research Station
Project Number: 6635-21000-046-00
Project Type:
Appropriated
Start Date: May 09, 2008
End Date: May 08, 2013
Objective:
Objective 1: Increase seed and conduct phytosanitary assessments for more than 1,000 NPGS Sorghum and Zea accessions which are subject to quarantine restrictions, so as to make additional certified, pathogen-tested seeds available to users.
Objective 2: Regenerate about 8,000 NPGS accessions with few seeds, low viabilities, and adaptations to equatorial latitudes and long-seasons, emphasizing Sorghum, Zea, Vigna, Cucurbita, Leucaena, and Psophocarpus. Record key agronomic traits such as host-plant resistance to biotic and abiotic stresses.
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 GRIN; harvest seed and examine for disease symptoms; and return seed to National Plant Germplasm System.
