Additional file 4: Table S2. of Quantitative trait locus mapping of Populus bark features and stem diameter

QTL associated with bark texture, diameter and bark thickness identified in Populus Family 52–124 in Oregon and West Virginia. Note: Chr: chromosome; V2: markers anchored on version 2 of the P. trichocarpa genome; V3: version 3 updated physical location; PVE: percent phenotypic variance explained; DD: homozygous for the P. deltoides allele, DT: heterozygous for the P. deltoides and P. trichocarpa alleles. LOD max determined using MQM mapping, value with *: above GW threshold, otherwise above CW threshold. Alternating white or grey shades represent unique QTL found in one or multiple replicates across years and sites. Indexes 1, 2, 3 or m designate: replicate one, two, three or replicates’ mean value for OR samples, whereas for WV samples only one replicate was available; BT: bark texture; D: diameter; BTh: bark thickness; 3y, 4y, 5y or 6y: # years old; OR: Oregon, WV: West Virginia. (Example for population: 1BT3yOR: replicate one, bark texture, 3 year old samples, Oregon site). (XLSX 19 kb)
