Comments about the QTL

Location approximate: original marker (BARC-029431-01692) is not found on the SoyBase Composite genetic map. QTL limited to an interval width at nearest marker. See publication for additional details.

Publication measured resistance to P. sojae infection, which was defined as the length of the lesion on a 14 day old plant at 7 days after inoculation. See publication for additional details.

Parent_1 was OX20-8, Parent_2 was PI 398841

Trait is reaction to Phytophthora sojae, the causative organism for Phytophthora root and stem rot and Phytophthora seed decay.
