Here's what Gabe 15 had to say in another thread:
" Gros Michel cultivars are fairly distinguishable from others in most cases, they have very prominent open and spreading petiole canals with distinct red coloration, especially on the wings."
...and a closeup of my "Bluefields" ( Gros Michel) petiole showing what this looks like so if the one from Thailand comes out something like this I'll be fairly sure of it.
