Location: Tropical Crops and Germplasm Research
Project Number: 6090-21000-052-00-D
Project Type: In-House Appropriated
Start Date: Mar 20, 2013
End Date: Mar 19, 2018
1. Regenerate seed supplies for priority accessions of crop genera Vigna, Cucurbita, Ipomoea, Leucaena, other tropical legume genera, Pennisetum, Zea and Sorghum which are adapted to equatorial latitudes, with approximately 420 restricted accessions and 1260 non-quarantined accessions of Sorghum and 40-50 restricted accessions of Zea cultivated and assessed for phytosanitary factors each year under quarantine conditions. 2. Characterize and evaluate (phenotype) germplasm accessions of priority genera, cultivated for regeneration and/or released from quarantine, for crop-specific descriptors and for priority agronomic and horticultural traits. Ensure that those data are incorporated into GRIN-Global or other databases.
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.
