Thank you Sharon for sharing so freely of your time to our hybridizing
questions. The posts on hybridizing this past spring and summer were so
rich with information that it's difficult to isolate the best ones.
I've saved a large number of these posts to re-read before the season
begins. I highly recommend beginning with the World of Iris for the
basics on hybridizing and colour and pattern traits. The information
provided on iris-L that is not provided in any book that I've read is
the behaviour of some traits. The one post I will be re-reading and
studying is Tom's post on the Punnett square that listed a large number
of traits and what could be expected from a cross. Other useful posts
are those on interspecies crosses and line-breeding.
As for Hybridizing 201, here are a few questions for everyone:
What genes are involved with "red" and "black" irises? Are these
colours dominant?
Is purple based foliage a dominant trait? Any chance that someone might
have the time and resources to put together a comprehensive list of
known dominant and recessive traits?
The plicata gene is recessive but also carries other recessive traits
such as glaciatas, luminatas and broken colours. These have been
written up in past AIS bulletins. Are there other recessive genes that
might have the same potential?
On line-breeding, how many generations can be pursued without weakening
the line, i.e., when should backcrosses and outcrosses be carried out.
I know that this will vary for the types of lines being pursued but a
rule of thumb would be helpful.
