- •
A total of 26 QTL on all chromosomes except 7, 9 and 11 were identified for 10 traits in the DS or WS using three MAGIC populations. Nine QTL corresponded to known QTL/genes.
- •
More QTL were detected using the 8-way population than the four-way populations. However, there are QTL that were not detected using the 8-way population were detected the four-way population.
- •
More QTL were detected by the combined analysis of multiple populations.
- •
QTL-by-season interaction was important for all QTL. Only nine of the 26 QTL were commonly identified across the two seasons.
- •
Four clustered QTL regions were detected. All these regions harbor well characterized genes/QTL.
