My experience breeding from the 'New Perspective' line is that flat x flat
gives 100% flat. I have bloomed about 300 seedlings of this type. However,
there is a variation in the expression of the character depending largely
on the growing conditions for the individual plant. Typically 'New
Perspective' blooms "normal" or partially converted the first year or sometimes just
early in the bloom season becoming flatter later. I think that there are
several kinds of flat tall beards and not all kinds are transmitted in the
same way. 'Judy Mogul' seems not to be a 'New Perspective' sort. The fact
flowers show white sections in the converted falls shows that it wants to be
an amoena, but the expression is altered by the flat factor. The fact that
a flat is not always flat can be a good thing. It is often these off type
flowers are the only ones with pollen and the only chance to breed from the
variety. I think those flat varieties which produce six good beards of the
same size are the best varieties to breed from.
I have good pods on 'New Perspective' with my flat intro for this year
'Orbison' and I am looking forward to seeing the seedlings bloom.
The biggest problem with the flats, at least for me, is form. Usually the
flats show up one in a cross so the chance of selecting good form is highly
problematic. This means that these sports need to be cross with 3 fall
type with great form, branching, etc. and back crossing these seedlings
together and with flats. Could take several generations to get anything worth
Some non-flat varieties will give flats when crossed with a flat. One way
to find these is to study parentages of flats that come from non-flats.
'Orbison' is from 'Diobolique' x ('World Tour' x 'Kathleen Kay Nelson').
'Diabolique" might be related to 'Indigo Princess' which Mike mentioned.
