Evaluation of Soybean Differentials for Their Interaction with <i>Phytophthora sojae</i>

Fig. 3. (A) For laboratory evaluations of the Rps genes, etiolated seedlings are inoculated 7 days after placing on germination paper. The resistance reaction is a necrotic area at the inoculation site; a susceptible interaction is a slowly expanding brown lesion.
