Mission

The Crop Germplasm Research Unit reflects the ARS Program Plan of mission oriented research and is focused on needs not addressed by the private sector, non-ARS research agencies, or that are uniquely suited to the ARS program. Included are integrated studies of introduction, classification, and maintenance of germplasm, elucidation of cellular and molecular DNA characteristics, characterization of germplasm with useful traits such as disease and insect resistance and quality factors, determination of genetic control of these characteristics, and development of genomic and bioinformatic systems to more efficiently define and utilize diverse germplasm. Several crop species are included. Pecan research focuses on host-plant resistance, genetic improvement, development of improved cultivars, and curation of the National Repository for Pecan and Hickory Germplasm and their characterization and evaluation. Sorghum research emphasizes evaluation and enhancement of germplasm with emphasis on molecular genetics and development of new genetic stocks. Cotton research includes curation and characterization of the National Cotton Germplasm Collection, and evaluation and enhancement of genetic stocks with emphasis on classical and molecular genetics, genomics, bioinformatics, and biotechhnology to facilitate development of improved cotton types for productive use by U.S. farmers.
