Raintree lists their almonds as Prunus amygdalus rather than Prunis Dulcis. Do you know if the nuts from the Almond “Reliable” have the potential
To have cyanid compounds/precursors since they appear to a be a cross from the Prunus Amygdalus?
Has anyone tested this variety of “almond” for these?

Hi, my name is Seamus and thank you for contacting Ask an Expert in regards to your almond tree question. Such a wonderful question you pose between Prunus amygdalus and Prunus dulcis specimens regarding cyanide compounds and their precursors. I only wish I had a quick answer for you.
I am not readily finding any easily accessible information that is completely scientific based, however, if you allow me a few more days I will continue to ferret out what I can for you. Hopefully, I will be able to provide you with a few scientific articles or at least references regarding your query. Please allow me until Monday to finish my research as I will be out of town, but I will be searching as time allows while I am away.
If you need a speedier response, please resubmit your question once again and one of my colleagues will address your questions. Thank your patience and understanding.
Again, thank you for contacting Cooperative Extension Ask an Expert.
Reliable almond is a cross between almond (Prunus amygdalus or Prunus dulcis, both refer to the same species) and peach (Prunus persica).
Any seed of almond, peach, or other rosaceous fruit (apples pears plums cherries, etc.) has potential to have cyanide precursors.
If they have cyanide precursors in any sufficient quantity, the seed is usually too bitter to eat.
