Individual QTLs are designated with the abbreviation of the trait, treatment, experiment number and QTL number
Chromosome number
Maximum-likelihood LOD score for the QTL calculated by QTLMAPPER 1.60
Additive effect
The positive or negative value indicates that allele from Yerong or Franklin increases the trait score, respectively
