A genetic linkage map of the A-genome of peanut – Linkage Groups A1 to A5. A genetic linkage map, obtained through the analysis of 93 F2 plants, generated from a cross between two diploid wild A-genome Arachis species, A. duranensis × A. stenosperma. Segregation ratios deviating significantly from the expected ratios are indicated with # (P ≤ 0.05), ## (P ≤ 0.01) or ### for highly distorted markers. Numbers on the left of each group are Kosambi map distances. Markers that amplified two loci have numbers _1 and _2 after the marker name. Disease resistance candidates marker names that are homologs to Arabidopsis NBS encoding genes are highlighted in bold and red, other disease resistance candidate marker names are highlighted in bold and blue. QTLs are indicated as bars running alongside linkage groups. Marker correspondences with the chromosomes of the model legumes Lotus japonicus and Medicago truncatula are indicated as colored blocks.
