Genetic linkage map constructed for the 103 RIL population derived from the cross of A. hypogaea JS17304–7-B × the synthetic amphidiploid JS1806. The 1819 SNP markers are shown at the right side the 21 linkage groups and the number of co-localized markers are indicated in brackets. Each marker is indicated with the probeset name provided by 48 K ‘Axiom_Arachis2’ SNP array [28]. A-subgenome LGs are represented in green, B-subgenome LGs are in purple and LG with no genome assignation is in gray. The bars in the y-axis represent the genetic distance in cM
