  • The sign before the additive effect is negative when A12 carries the “early” allele and positive if A12 carries the “late” allele; for individual QTL, the % variance explained is a2 × 100/2VA, except for that for linkage group O9 with two QTL, which allows for the effect of linkage and is shown in parentheses. The estimates of VA are taken from Table 2.

  • a Item not significant but most likely QTL position and effect added for comparison.
