None of the common citrus virus or viroid diseases can pass through seeds. Reports from Argentina, years ago, about psorosis passing through seed were false.
I would wonder about greening bacteria, but then, branches that are affected usually produce fruit with aborted seeds, so finding a viable seed may be a challenge there.
With that one possible exception, I am unaware of any disease of citrus that is seed-transmitted (and I've been teaching citrus pathology for 25 years).
