*: P < 0.05, **: P < 0.01 and ***: P < 0.001.
b
Proportion of variability explained by the putative QTL. Bold-consistent genomic regions associated with Phomopsis pod blight resistance that was scored under glasshouse and field conditions.
c
Alleles from QTL with positive additive effect value are from Kiev-Mutant. Alleles from QTL with negative additive effect value are from P27174.
d
Interaction effect between pairs of QTLs.
