Investigations on Barley Diseases and Their Control Brian J. Steffenson Department of Plant Pathology University of Minnesota ANNUAL PROGRESS REPORT Executive Summary Plant diseases are one of the most important constraints to barley (Hordeum vulgare) production and quality in the United States. Our Cereal Disease Resistance Project is part of the Minnesota Barley Improvement Program team that develops sixrowed malting barley cultivars for the Midwest. The primary mission of the Cereal Disease Resistance Project at the University of Minnesota is the control of economically important barley diseases. For many diseases, this goal is best achieved through the development of cultivars with genetic resistance. Thus, the long-term goal of this project is to develop the knowledge base, resources, and germplasm for achieving durable disease resistance in malting barley cultivars. In addition to these goals, it is also essential to conduct disease surveys and monitor pathogen populations for new virulence types. In 2006, breeding lines were sown for evaluation for resistance to spot blotch, Septoria speckled leaf blotch (SSLB), and net blotch. Durable resistance has been achieved for spot blotch. Our evaluations ensure that this resistance is not lost when exotic material is introgressed into the breeding program. Indeed, we identified several susceptible lines from Busch Agricultural Resources, Inc. (BARI) breeding program in this tests. These lines have now been discarded. We are also working on increasing the level of resistance to SSLB and net blotch in the Minnesota program. Toward this end, we have identified a number of agronomically advanced lines with high levels of resistance to both diseases. Our annual disease survey was conducted on July 12-14 in 2006. Fusarium head blight, net blotch, and SSLB continue to be common diseases on barley, but their severity was reduced due to dry weather in 2006. Bacterial blight also was found in a few fields in 2006. Additional pathogen isolates were collected from this survey and were stored in our pathogen collection. Pathogen isolates are an essential resource for resistance breeding efforts and the identification of novel sources of disease resistance. They are also useful as a historical record of virulence shifts in pathogen populations. Our research goals all directly address AMBA’s primary objective of developing malting barley cultivars with improved agronomic and quality characters. The deployment of superior malting cultivars with disease resistance will help ensure that an adequate supply of high quality malting barley is available to the malting and brewing industry.
