Estimating optimum number of marker loci for genetic analyses in Cynodon accessions

► The aim was to estimate genome sampling size of 192 Cynodon accessions for genetic analyses. ► Cynodon genotypes including 5 ploidy levels were genotyped using SRAP markers. ► Correlations between 5 and 10, 10 and 20, 20 and 40, 40 and 60, 60 and 80, 80 and 100 SRAP marker data sets were compared. ► 20 markers appeared to be sufficient in Cynodon genotypes by using Dice' procedure
