Comments about the QTL

QTL was detected for resistance to 2 different isolates of P. sojae using lesion length for PT2044C2.S1, and plant height for 1.S.1.1 to quantify resistance. First listed data presented in SoyBase; see publication for additional details

P value and R2 obtained by one-way ANOVA

Parent_1 is Conrad, Parent_2 is Sloan

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