^a MapA = Gy14 × PI 183967 RIL (CSH-RIL) [42]; MapB = Gy14 × 9930 F₂ (CSS-F2 map) (Additional file 2: Table S4, Figure 2); MapC = 9110Gt × 9930 RIL (CSS_RIL) [45].
^b Chr = Chromosome or linkage group.
^c Marker loci of linkage group (Chromosome) 4 from the Gy14 × PI 183967 RIL (MapA) and 9110Gt × 9930 RIL (MapC) maps were not used in map integration. Numbers in this row were listed for comparison purpose only. n/a = not applicable.
^d The consensus map for Chromosome 4 was integrated from two intra-varietal cucumber component genetic maps: the PI 249561 × PI 308915 F₂ map (CSS-PI-F2 Map - MapA) [28] and the Gy14 × 9930 F₂ map (CSS-F2 map - MapB) (Additional file 2: Table S4, Figure 2).
^e Average genetic distance between adjacent markers (marker interval) in centimorgan.
