Table 5 Quantitative trait loci (QTL) associated with yield related traits identified by inclusive composite interval mapping of additive effects. Trait names, QTL, linkage group (LG), LG position, the 1-LOD support interval in cM unit (LOD interval), the logarithm of the odds (LOD), the percentage of the phenotypic variation explained by QTL, the additive effects (Add) of the QTL are presented

From: High-density linkage map construction and mapping QTL for yield and yield components in autotetraploid alfalfa using RAD-seq
