Does somebody know whether Keraji & Changsha mandarins have zygotic or nucellar embryos or if both with what percentage?

Till, the subject interests me but I have not found Keraji & Changsha.
Here are two links where I found some values:

Changsha are polyembryonic. I have never grown Keraji from seed, but I believe they are also.

I tried to germinate this winter 10 seeds from my Keradji, they were very sensitive to the root rot but one seedling that survived had atypical leaves and probably was zygotic.

Thank you for your replies! My next question would be how many zygotic seeds the plants produce besides the nucellar ones.
By the way, the Poncirus tree in Mainz botanical garden has nearly 100% monoembryonic seeds. What a luck! I hope they are also zygotic.
