Amphidiploid is 12/12/8/8  these are SDB
There can't be cross overs between any chromosome from 8 set and 12 set, as they never pair up in meiosis. Crossovers only occur in paired chromosomes. No pairs = no crossovers. Like, never ever. If they ever did, their would be unbalanced chromosomes, and it wouldn't be viable. that is the meiotic cell would die, or any zygote formed would die.
IB is 12/12/12/8 So can be pumilla spot, on one of the chromosomes from the "8 chromosomes" set.
RE; Chocolate Truffle. TB X pumilla = SDB No exceptions. And for kickers, ruffles" a recessive trait that just isn't present in pumilla species. So where are genes for ruffles coming from? Hell's Fire is a reddish black, with multiple dosages of Ae (check pedigree) Thus all seedlings will be purple in a cross with a yellow. So are you still believing this pedigree?

Amphidiploid version could.

Agree, spots are interesting.

TB e-register from pumila, first generation.   There is another one
registered as a TB, but class is probably a typo - it's IB height.
Others SDB breeding? fertile IBs? cross overs?

CHOCOLATE TRUFFLE    (Mark Grumbine, R. 2006) Sdlg. MG04-407-7. TB, 29"
(74 cm), EM     S. light yellow-brown; F. dark mahogany brown, light
yellow area around beards and shoulders; beards orange; ruffled. Hells
Fire X I. pumila, yellow

eagerly waiting to see the '39 checklist (Mike, any more TBs registered
from that era from pumilas?)

Are there more?  What about the pumila spot work that Blyth was doing,
trying to bring spot 'up' to TB size? Zing Me.
