The tetraploid MTB' s we have introduced took many generations of
crosses to finally get seedlings that met the rigid class requirements.
(approximately 18 years ) We used Iris aphylla to miniaturize the tall
bearded iris. With the help of Ben Hager's seedlings and a couple he had
introduced that were near MTB size, and with the advise generously given
by Bob Schreiner we eventually were able to reach our goal. I. aphylla
has multi branching and buds. Most branch from the base (within one inch
of the rhizome). They throw multi budded and branched seedlings when
crossed with TB's. We now have lines of seedlings which are producing
first generation MTB's. Attached is a photo of one which was selected
best seedling at the Portland Show in 2002. The beauty of the tet's is
that we can produce MTB's in any color combination and many very smooth
clean colors with the form of the most advanced TB's. Now we are
getting rebloomers. In addition, we have several that meet the SDB
class in size but bloom with the tall bearded. That certainly extends
the bloom season. See attached photo of 48 chromosome SDB.
There will be some who are offended by a SDB that blooms with the TB's.
yet other's applaud advances made to extend bloom seasons.
The field is wide open not only for MTB's but SDB' and IB's and BB's.
Our iris are as fertile as the TB's! They are all well branched,
multibudded, giving a long bloom season.
Lynn Markham is working with aphylla and aphylla derivatives. Ken
Fisher has been incorporating them in his lines as has Terry Aitken, and
even Lynda Miller's husband. Cindy and Steffy Rust are working on a line
of reblooming iris out of aril using aphylla derivatives.
I hope this answers your inquiry.
