FIGURE 3

LOD score distribution of QTL along the 12 LGs of the high density genetic map. LOD cutoffs for traits with significant QTL are shown by the dashed lines. For traits with no significant QTLs, LOD cutoffs are not drawn. Abbreviations for traits are: chilling requirement, ChillReq; cold hardiness, ColdHard; diameter, Dia; soluble solids, SS; firmness rated by squeezing the berries, Firm; firmness measured with a Texture Analyzer by pressing the berries equatorially, 20 S Firm; firmness measured with a Texture Analyzer by puncturing the skin, 3 mm Firm; shoot expansion, SE; early bloom, EB; full bloom, FB; petal fall, PF; early green, EG; late green, LG; 75% blue, 75BLUE. LOD cutoff values for traits are: ChillReq, 7.65; ColdHard, 7.38; Weight, 11.52; Dia, 9.45; Color, 10.14; Scar, 11.89; Flavor, 10.52; SS, 20.98; Firm, 11.33; 20 S Firm, 16.50; 3 mm Firm, 12.21; SE, 16.20; EB, 11.16; FB, 15.98; PF, 12.89; EG, 11.25; LG, 8.81; 75 BLUE, 12.32. (A) QTL analysis of chilling requirement and cold hardiness. (B) QTL analysis of fruit quality traits. (C) QTL analysis of timing of developmental traits. Phenotypic data collected in different years is represented by different colored lines.
