Abstract/Contents:Presents a study initiated during 2007 to determine whether reduced-input sustainability can be achieved through the genetic enhancement of turfgrass germplasm. Notes that the primary objectives of the study were to "(1) use genetic and biotechnology approaches to identify and develop turfgrass germplasm with improved biotic and abiotic stress resistance," and "(2) identify molecular markers associated with desirable traits and...combine useful traits into germplasm able to grow with reduced inputs." Details methods and materials used during the experiment, stating that "plants from an experimental creeping bentgrass mapping population were established and inoculated with the dollar spot fungus at the University of Maryland turfgrass research center." Reports that "extensive disease development occurred for the second year, and clones with the highest levels of resistance were selected for further evaluation." Mentions that "analysis of bentgrass chromosomes identified seven linkage groups that contribute some level of heat and drought tolerance," concluding that "these chromosome locations will [be] more intensively studied to better understand the role each plays in conferring stress tolerance."

USGA Summary Points:A new type of bentgrass genetic marker was developed using sequence data based on Miniature Inverted Transposable Elements (MITEs). MITEs appear to be common in Agrostis and the markers are useful in evaluating the genetic diversity of germplasm Dollar spot resistant and susceptible plants are now being investigated to identify which genes are expressed, and potentially confer resistance in bentgrass Analysis of bentgrass chromosomes identified seven linkage groups that contribute some level of heat and drought tolerance. These chromosome locations will more intensively studied to better understand the role each plays in conferring stress tolerance.
