  1. a LOD threshold of MQM was estimated after 1000 permutations and 5% error rate was 2.59.
  2. b R2 indicates the percentage of additive phenotypic variance explained by each QTL
  3. c Effect size of each QTL, calculated as μA - μB, where μA is the mean of RILs with the L58 allele and μB is the mean of RILs with the R-o-18 allele
  4. d E3552M3 is an AFLP marker, thus with unknown location. The right border of the 1.5-LOD interval is conservatively set at the end of the chromosome. The closest marker, BrID101283, is ~ 1 LOD from the LOD peak and it is located at 36.04 Mb
