Comparison of the means of fruit ethylene production and firmness or firmness loss among allelotypes of MdACS1 as defined by marker ACS1 (a and d), and among those of MdACS3a as defined by markers CAPS866 (b and e) and CAPS870 (c and f). The allelotypes are annotated similarly as those in the legend of Figure 3. Colors of column in blue, orange, green, purple and turquoise represent days 0, 5, 10, 15 and 20, respectively. The statistical tests were conducted independently within each of the five storage time points (days 0–20). Significance levels are indicated with letters (shown above the columns in the chart), where different letters indicate P<0.05. The numbers of accessions observed (n) for each allelotype are presented accordingly (shown above the letters for significance). Error bars indicate s.e.
