Colonial Bentgrass Genetic Linkage Mapping

摘要

Colonial bentgrass (Agrostis capillaris) is an important turfgrass species used on golf courses in temperate regions, although the related species, creeping bentgrass (A. stoloniferd), is often preferred. One of the major management problems for creeping bentgrass is the fiingal disease called dollar spot. Colonial bentgrass as a species has good resistance to dollar spot and may be a source of novel genes or alleles that could be used in the improvement of creeping bentgrass. As one approach to ultimately identifying the genes in colonial bentgrass that confer dollar spot resistance, we are developing a genetic linkage map of colonial bentgrass. To provide tools for mapping genes, we have generated expressed sequenced tag (EST) resources for both colonial and creeping bentgrass, and have developed a new approach to gene-based marker development.
