Ace Summer Emotions
A nice collection
of dahlias with
a number of varieties that do not fit
in one of the other collections
but will fill any dahlialover with enthusiasm
Many of these varieties have
and recently made successful crossings
open the way to soon new introductions.
As shown by this photograph.
There are so many, many different dahlias. And their differences can be
based on height, floral shape, flower size and colour. Most dahlias we
see nowadays are hybrids. They have been developed as a result of both
purposeful and accidental crossings. In these 'accidental' crossings,
it is the bees that have done the work, but in these cases it is difficult
to determine which plants have been the parents of the new offspring.
Even when purposeful crossing is being conducted and the parental plants
are carefully selected, it is still difficult to know ahead of time what
the results will be. This is because dahlias are octoploids: unlike the
usual diploids, these plants have eight different groups of homologous
chromosomes containing hereditary factors. This means that when crossing
them, many different new combinations are possible that can then determine
the characteristics of the new plant. By gathering information about the
more dominant and less dominant traits during crossing activities, the
breeder of dahlias attempts to reach a certain goal. Even with all this
planning, however, a new dahlia will sometimes be produced that looks
very unlike what had been expected. And it can display such outstanding
qualities that it holds the promise of being a very useful innovation.
These dahlias - the ones that cannot be fitted into any of the other collections
but are ones that every dahlia enthusiast will want - earn a place in
this 'ACe' series.
