Growing loquats in the Pacific Northwest

My air layered plant I propagated last year has this wound on it. I can’t tell if it’s just some wound that is healing weirdly, or if this is some disease. Top growth looks normal, and it’s still in a pot. Existed when it was still on the mother tree last summer but was just more subtle. Would appreciate some thoughts! I have a more mature scion I was going to graft on anyway so I think in any case I’ll just cut below the wound and cleft graft in the coming weeks.
