Linkage group and the estimated confidence interval of QTL position in brackets (in Kosambi cM).
F-values of significance of each QTL.
Estimated additive effect. Positive values indicate that alleles from PHA1037 have a positive effect on the traits, and negative values indicate that positive effect on the traits is due to the presence of the alleles from PMB0225.
Percentage of the phenotypic variation explained by additive effects.
Experiment-wide P-value.
P = 0.05,
P = 0.01,
P = 0.001.
SDC, stem disease score; SAUDPC, stem area under the disease progress curve; PDC, petiole disease score; PAUDPC, petiole area under the disease progress curve; LDC, leaf disease score; LAUDPC, leaf area under the disease progress curve.
