HYB: TB: possible "t" in Return of Innocence (response to Linda Mann)
Linda and anyone else interested,
My speculation that RETURN OF INNOCENCE might have two or more "t" doses may
seem far fetched at first, but let me point out my basis for the claim.
One of the grandparents is MESMERIZER of Byers' which has a red beard--tttt.
Behind ZURICH two generations is SKY HOOKS, one parent of which--MOON
MISTRESS--also is tttt with red beard.
Throughout the remaining ancestry of Return of Innocence is a wide range of
very high quality whites and blues. It is interesting to remember that the
probably parent of Loomis' SQ-72/ PIKE'S PEAK PINK (a tttt variety) is
PURISSIMA, ancestral many times over to nearly every white and blue in
existence. If true, the "t" factor would be very wide spread among whites and
blues in one dose, and more rarely, two, an assertion simply based on
probabilities of inheritance.
Keith Keppel has the informed opinion that the "t" factor comes into modern
tetraploids through KASHMIR WHITE, which is also ancestral to nearly all if
not all modern blues and whites.
The contribution of the "t" factor in Return of Innocence from Mesmerizer may
be none, one or two doses. All of the other fabulous quality blues and whites
involved in its remaining ancestry very probably contribute at least one "t"
dose--or perhaps not. The only way to find out is to try crossing Return with
red-bearded sorts then crossing a couple or more of those seedlings with a red
bearded variety. In a seedling set in the first generation of several
seedlings (at least a dozen or more) at least one red-bearded seedling would
show if Return is "tt." The red may be as subtle as that of FOGBOUND,
however, considering how white the beard of Return of Innocence is. You have
to have at least some yellow to get the chemical genetic precursors to
tangerine. If none show in a progeny of well more than a dozen seedlings,
then using Chuck Chapman's suggestion of how to recognize "ttt" carriers, pick
a couple of them and cross to a red bearded cultivar. If half the progeny
have tangerine beards, that would demonstrate that Return has at least one "t"
Clear as mud? Since the quality of RETURN OF INNOCENCE seems so high, and
especially considering its ancestry, one could hardly go wrong in
incorporating this Sutton introduction in a breeding program looking for those
qualities Linda Mann is seeking.
It might be rather fun to ask Mike Sutton to tell us what sorts of seedlings
they have seen from RETURN OF INNOCENCE so far--and if any of the crosses were
with tangerine/red/orange or whatever tttt sorts.
IMHO--or not so humble, perhaps.
