Location of volatile QTL that are stable across location for the ‘ Granada’ map. The two consistent QTL found at the locations EJ and AA (for 3-cyclohexene-1-acetaldehyde,_a,4-dimethyl) and EJ, AA, and IVIA (for weight) are shown. The QTL are colored according to the additive effect (a) that is exerted, red for negative a and blue for positive a. For the volatile QTL, the colored circle (according to Figure 3) indicates the cluster that the controlled volatile belongs to. Bars and lines represent 1-LOD and 2-LOD support intervals.
