Abstract/Contents:"Breeding and cultivar development in bermudagrass (Cynodon spp.) is hampered by the limited information regarding its genetic and phenotypic diversity. To explore diversity in bermudagrass, a total of 206 Cynodon accessions consisting of 193 common bermudagrass (C. dactylon var. dactylon) and 13 African bermudagrass (C. transvaalensis) accessions of worldwide origin were assembled for this study. Genotyping-by-sequencing (GBS) with ApeKI enzyme was employed for genetic marker development. With a minor allele frequency of 0.05 and a minimum call rate of 0.5, a total of 37,496 raw single nucleotide polymorphisms (SNPs) were called de novo using the TASSEL 3 UNEAK pipeline. Population structure analysis using ADMIXTURE revealed four subpopulations in this germplasm panel, and this was found to be consistent with principal component analysis (PCA) and phylogenetic analysis results. The first three principal components explained 15.6 %, 10.1 %, and 3.8 % of the variance in the germplasm panel, respectively. Genetic diversity parameters including nucleotide diversity or average pairwise divergence (π), estimated mutation rate or expected nucleotide diversity (θ), Tajimas D statistic, and Fst statistic revealed substantial genetic variation in Cynodon genus, demonstrating the potential of this germplasm panel for further genetic studies and cultivar development in breeding programs."
