Well, finaly had some time to check my hybrid pods. NoID trumpets x Black Dragon and regale gave me a looooot of viable seeds as I expected. On the other hand not a single viable seed from my henryi x sargentiae or henryi x sulphureum crosses. Few 1000 seeds all empty! Today I opened my last pod: sargentiae x henryi. To be honest I didn't expect anything. Pod was small, soft but still green. To my surprise I have found 5 viable seeds!
I'll let them dry and then store in the fridge till spring.
Also I found additional 4 seeds with embryo but no endosperm:
ER should be used on these but unfortunately I don't know how to do it. Might just put them on the moist soil surface under light and see if anything happens.
