Looks like I might have a possible mutation on my third generation peach x almond hybrid.
This is its parentage:
Calired interspecific peach x unknown pollen.
I originated Calired Interspecific peach from a cross between Luna Peachmond, seed parent, x Sweet Bagel peach, pollenparent.
I originated Luna peachmond from a cross between F1 Nonpareil almond, seed parent, x Elberta peach, pollen parent.
