Turfgrass Biology, Genetics, and Breeding Seashore paspalum ( Paspalum vaginatum Swart) Occurrence Handle1:CAS:528:DyaK2sXlvVCltb8%3D This is the first report of the transfer of SSR markers from major field crops to newly emerged environmental turfgrasses.ĪrticleTitleGenome relations between tetraploid Paspalum dilatatum and four diploid Paspalum species The number of SSR markers required for germplasm characterization and evaluation is discussed. This led us to determine that 18 of the transferred SSR markers were sufficient for genetically differentiating the investigated germplasm accessions. Two very similar dendrograms can be generated from either 109 or 209 polymorphic bands. The Paspalum accessions clustered into three major groups. In total, 209 polymorphic bands were detected from these 40 SSR markers, with an average of five polymorphic bands per marker. Forty transferred polymorphic SSR markers were selected and used for characterization and evaluation of seventy-three Paspalum accessions. The high level of polymorphism is directly related to the high degree of heterozygosity maintained by its way of reproduction, i.e. The polymorphism level for transferred SSR markers was 51.5% within species ( Paspalum vaginatum) and 87.1% among Paspalum species. This would be a very efficient approach for DNA marker development for species which are not well studied molecularly. The transfer rate was 67.5, 49.0 and 66.8% respectively. One hundred and thirty SSR markers from wheat, maize and sorghum were screened for the transferability to Paspalum.
