| Abstract/Contents: | "Colonial bentgrass (Agrostis capillaris) is a tetraploid rhizomatous bentgrass that generally exhibits improved resistance to the important fungal disease dollar spot and has more tolerance to water deficit stress than the more widely grown creeping bentgrass (A. stolonifera). Interspecific hybridization between these two species is possible and efforts to understand the genetic mechanisms of enhanced biotic and abiotic stress resistance in colonial bentgrass are proceeding. To gain a better understanding of the level of genetic diversity in cultivated colonial bentgrasses and to determine if genotypes with improved interspecific hybridization potential can be identified nine colonial bentgrass cultivars and one creeping bentgrass cultivar were screened with 48 colonial bentgrass derived simple sequence repeat markers (SSR). Twenty-one primer pairs were found to produce reliable amplification and these markers were scored using High Resolution Melt analysis to generate haplotypes that were used to evaluate cultivar relationships. The nine colonial bentgrass cultivars could be placed into two groups and overall showed limited levels of diversity. The creeping bentgrass cultivar was distinct and individual genotypes within each species exhibited haplotypes more common in the alternate species suggesting that these markers may be useful for selecting genotypes with enhanced interspecific hybridization potential." |
