Technical Abstract: Diseases and insect infestations have been a challenge to barley producers since the beginning of its cultivation as a crop. Continuous evolution and movement of diseases and insects, and changing agricultural practices and climactic conditions, interact to present new challenges and threats to production. The re-emergence of Fusarium head blight in epidemic proportions represents a major threat to the economic viability of barley as a major crop in the midwestern United States, while certain regions of the western United States are impacted by the Russian wheat aphid and barley stripe rust. The presentation will focus on work related to identifying and developing germplasm that can address these challenges, and give an overview of other work related to spot blotch, net blotch, barley stripe mosaic, Psuedomonas kernel blight, barley yellow dwarf, and the cereal leaf beetle. Through extensive collaborative research efforts with plant breeders, pathologists, geneticists, and other plant scientists, the USDA-ARS National Small Grains Germplasm Facility provides a key role in the national effort to reduce disease and insect related losses. Contributions of this ARS facility include significant roles in the coordination of collaborative research, data collection and distribution, identification and distribution of useful germplasm from the National Small Grains Collection, and the production, distribution, and release of improved germplasm and cultivars.
