** = significant at the 0.01 and * = significant at the 0.05 probability level. 1LG = Linkage group. 2Absolute position from the top of the LG in centiMorgans (cM).3One-LOD support interval in centiMorgans: Refers to the region flanking each QTL peak in which LOD scores decline by one. 4Markers flanking the likelihood peak for a putative QTL. 5 a = additive effect. A positive sign means an increase of the trait value due to nmsT2100 alleles. d = dominant effect. a and d estimates, as well as total R2 and LOD score values were obtained from a simultaneous fit of all putative QTL using multiple regression. 6QTL detected below the LOD threshold.
