Pearl millet SNP discovery and allele frequency. a Flowchart of genotyping-by-sequencing for 511 pearl millet accessions. “SL” represents the pools with Senegalese landraces, “GA” represents the pools with global accessions, and “SLGA” represents the pools with accessions from both germplasm sets. SL3 had the same accessions as SL2 but the library preparation failed. For SLGA2, Senegalese landraces were duplicates of the Senegalese landraces in SLGA1, but the sequence quality was low. b The minor allele frequency distributions of observed SNPs (gray bar) compared to the neutral allele frequency spectrum (red line) in the 500 pearl millet accessions
