Overview of the QTLs identified for fruit mean l-AA, DHA, and total l-AA contents, fresh weights, and susceptibility to flesh browning on the genetic linkage maps of Telamon and Braeburn
QTLs with a significance level of LOD > 3.0 but less than 3.5 are shown in italics and were not used to calculate the total explained percentage of population variance per trait (SUM). ****, QTL for DHA localized using the Kruskall-Wallace nonparametric mapping function, with significance level of P = 0.05.
