Abstract/Contents: | "Limited genetic and phenotypic diversity is a hindrance for bermudagrass breeding and cultivar development. A germplasm panel of 206 accessions, including 193 common bermudagrass (C. dactylon var. dactylon) and 13 African bermudagrass (C. transvaalensis) accessions of worldwide origin was assembled. DNA sequencing libraries were prepared following the genotyping-by-sequencing (GBS) protocol to get genetic markers. A total of 37,496 raw single nucleotide polymorphisms (SNPs) were called de novo using the TASSEL 3 UNEAK pipeline with a minor allele frequency of 0.05 and a minimum call rate of 0.5. In this germplasm panel, population structure analysis with ADMIXTURE revealed four subpopulations, which were shown to be congruent with the results of principal component analysis (PCA) and phylogenetic analysis. The first three principal components explained 15.6 %, 10.1 %, and 3.8 % of the variance in the germplasm panel, respectively. Substantial genetic variation in genus Cynodon is revealed by 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 demonstrating the potential of this germplasm panel for further genetic studies and cultivar development in breeding programs." |
