Curator II – Amaranth, Millets, Miscellaneous Umbels
USDA-ARS-MWA-PIRU; Iowa State University
David is the Plant Germplasm Curator for numerous crops and wild relatives including Amaranthus, Celosia, Chenopodium, Coronilla, Dalea, Galega, Melilotus, Perilla, Spinacia, miscellaneous Umbelliferae, and the millets: Echinochloa, Panicum, and Setaria.
David Brenner conducts enhancement breeding research with potential benefits in both production agriculture and ornamental horticulture. In Amaranthus he is working to improve dwarf grain types, reduce seed shattering, improve resistance to Phomopsis, and characterize male sterility in the germplasm collection. In Panicum he is making wide crosses within the primary gene pool to broaden the genetic base of new proso millet cultivars.
David works in crop groups that have taxonomic controversy and difficulty. He maintains communication with taxonomists and personally makes large numbers of taxonomic determinations.
David also develops methods for improved germplasm regeneration. He is interested in methods for plants that grow in the winter, and are therefore not adapted in Iowa. He recently published a paper on Melilotus regeneration methods.
