QTL mapping
As proposed for additive, dominant and epistatic QTL mapping in
biparental populations (Li et al., 2015), we employed inclusive
composite interval mapping (ICIM) for QTL detection, using IciMapping
V4.1 (http://www.isbre eding .net/). A LOD score of 2.5 was used as
significance of QTL detection. Permutations were set to 1000 at asignificance level of 0.05. The inclusive composite interval mapping
addition (ICIM-ADD) method was selected for QTL mapping (Li et al.,
2007).
