  • Exp, differentiates experiment A from experiment B. Overall trait mean and standard deviation (SD) are provided for all trait-by-isolate combinations within each experiment. Bay and Sha indicate trait mean values for parental accessions interplanted with RILs. H2 is the broad-sense heritability estimate for each trait, estimated as the proportion of phenotypic variance explained by genotype in a one-way ANOVA model. LOD represents the significance threshold for QTL (P = 0.05) obtained by permutation tests.
