I'm not sure about the genetics, either. However, I think it is not the result of a major gene as we see in some hybrid varieties, but a more general resistance. There were heirlooms with resistance to earlier races, but not against what is showing up now. Matt's Wild is an exception, as you may know.

Every habrochaites rootstock that I tried seemed to be completely resistant to Septoria, so it may be a common property of all S. habrochaites lines. I think there is a good chance your interspecies hybrid will also be resistant.
