  1. Only associations at p < 0.005 observed in both GLM and MLM analysis or in GLM and IL analysis (Additional file 5, Figs. 2, 3, 4, 5 and 6) are shown. For each trait (FS fruit shape index, FF flesh firmness, FCHl, FCa and FCb L, a* and b* Hunter coordinates of flesh color, SSC soluble solid concentration in flesh, SUC, GLUC and FRUC sucrose, glucose and fructose content in flesh) with significant association, the backcross population where it was identified, the significant marker with its chromosome and genetic position in cM, the statistical significance of the association (p), the percentage of phenotypic variance explained by the marker (R2), the allelic effect (negative when MAK alleles increase the trait value), and the IL that showed a significant effect in the trait and carried the marker introgressed from MAK (identified with the Dunnet’s test in the IL analysis), are also indicated
