Triploids have always intrigued me ... do you know if the low fertility is just on the pollen side, and if the cross is successful, whether the pods are set consistently (Tet pod vs. Dip pod)? Thanks so much for the list of triploids - it prompted me to wonder if there might be some additional ones in the ATP database, and indeed there are:
Adel Ga's Southern Hospitality
Crazy Miss Daisy
Desperado Love
Frankly Fabulous
Judge Judy
[EDIT] Fred Manning, the hybridizer, notes this cultivar's listing is in error (not a Triploid) and will update the database -- Lillian's Little Joe
Sahara Splendor
Shout from the Mountaintops
Sweet Tranquility
Swiss Legacy
I'll try to add the links later (back to bed with a cold...). I think I will have to get what ones I can and give this natural bridge a try! And, I'm going to ask the obvious-but-I'm-not-feeling-quite-sure question ... I assume that Trips have three sets of chromosomes, with intermediate sized/shaped pollen, and in hybridizing over the bridge they either pick up an additional set of chromosomes from the Tet parent or lose the extra one via the Dip cross?
