Plant Exploration in the Southwestern United States to Collect Sunflower Germplasm for Crop Improvement
National Germplasm Resources
2013 Annual Report
1a.Objectives (from AD-416):
To obtain germplasm of sunflower (Helianthus spp.) for conservation in the U.S. National Plant Germplasm System.
1b.Approach (from AD-416):
Germplasm of sunflower will be collected in different locations in the U.S. Collecting permits will be obtained as required by law. Germplasm will be collected in the form of seeds, cuttings or other plant parts and will be documented with locality, latitude and longitude, elevation, plant description, and growing environment. Herbarium voucher specimens will be made as appropriate. Samples of germplasm and associated documentation will be deposited with the U.S. National Plant Germplasm System. A detailed trip report, including information on all samples obtained, will be provided to ARS.
A plant exploration to collect germplasm of wild sunflower was conducted in New Mexico and Texas in October 2012. Germplasm was obtained from 33 wild populations of nine different sunflower species. The germplasm was added to the U.S. National Plant Germplasm System.
