Genetic diversity parameters within the Core Sample (171 accessions) and within the 6 genetic groups identified.

agroup number as defined in the text. UN corresponds to unassigned accessions. CS: Whole Core Sample.bnumber of accessions assigned to the different genetic groups. Assignment was based on full congruence between the three marker systems (cf Table S1, column “Group Consensus Schemes”).craces present in the group defined according to grain and spikelet morphology (Harlan and De Wet, 1972). B: bicolor, C: caudatum, D: durra, G: guinea, K: kafir, Gm: guinea margaritiferum sub-race defined according to Snowden's classification.dAf: Africa, As: Asia, ME: Middle East, SAf: Southern Africa, WAf: Western Africa.eallelic richness and private allelic richness computed with HP-Rare are normalized values.fexpected heterozygosity estimated with PowerMarker. Standard deviations estimated with 1000 bootstraps are shown in brackets.
