Search by the QTL/MTL label given by the GDR team. 

An example QTL qSI.TE-ch5.1 indicates that:

qSI = a QTL for Self Incompatibility trait,
TE = this QTL has been mapped on the map drived by Texas x Earlygold population,
ch5 = this QTL is located on chromosome/linkage group 5 of the map, and
.2 = the self incompatibility trait has more than one locations on the chromosome, and this QTL is the second one in order of that along with the chromosome.
