Table 3 Results of the analysis of molecular variance (AMOVA) for groups detected by different population structure analyses.

From: Genotyping by sequencing provides new insights into the diversity of Napier grass (Cenchrus purpureus) and reveals variation in genome-wide LD patterns between collections
