Hallo Lucky,
thank you again for your very clear words!
Let me forget C. cordiformis (maybe only for: "Abbot" C. illinoensis. x 
C. cordiformis).
Let me use e.g. C. ovata for C. ovata only and
C. laciniosa only for C. laciniosa only.
And let me import more Northern Pecan seeds from USA as rootstock for 
probably all different Carya.
Thank you!

Ciao
Hans
