Abstract

Filtered SNP calls in .ped format from "Hybridization, polyploidy and clonality influence geographic patterns of diversity and salt tolerance in the model halophyte seashore paspalum (Paspalum vaginatum)". We used GBS to genotype 218 P. vaginatum and P. distichum accessions collected from the US Gulf and Atlantic coasts plus available USDA germplasm. We confirm that P. vaginatum and P. distichum are genetically distinct and that the coarse-textured ecotype of P. vaginatum is composed of hybrids between fine-textured accessions and an unidentified paspalum species. These hybrids vary in ploidy and subgenome composition which may influence their geographic patterns of adaptation to saline environments.
