Comments about the QTL
Parent 1 is PI407162, Parent 2 is V71-370
Location approximate: no specific marker given in publication. QTL limited to an interval at the nearest marker. See publication for additional details.
Variable used to assess resistance to P. sojae was lesion length using a tray test
Publication reported values for 3 trials over 2 years; only one trial presented in SoyBase; see publication for more information
Trait is reaction to Phytophthora sojae, the causative organism for Phytophthora root and stem rot and Phytophthora seed decay.
