Abstract/Contents:Presents a study conducted to "use genetic and biotechnology approaches to identify and develop turfgrass germplasm with improved biotic and abiotic stress resistance." Describes the experiment and the methods used. Reports that "the commercial cultivars had the lowest mean disease severity in each experiment."

USGA Summary Points:AFLP marker results indicate that Danthonia spicata (Poverty grass) is primarily a self-fertile species, however, a small percentage of outcrossing does occur. A high level of dollar spot (Sclerotinia homoeocarpa) infection in 2009 caused differing responses among bentgrass germplasm, planted in Maryland field trial. Tall fescue plant introductions (PIs), inoculated with Rhizoctonia solani and R. zeae, showed varying degrees of tolerance to both diseases. 1,300 Miniature Inverted-repeat Transposable Elements (MITEs) display markers were used in a diversity analysis of Agrostis species. The markers established the relationship between ancestral diploid material and cultivated varieties, and showed reduction in genetic diversity in new cultivars.
