Re: LA cross question

Sandy,
 
I hybridize Louisianas and almost always get a few albinos among newly germinated seedlings.  Usually they are among the first to germinate.  They don't occur randomly, but seem to pop up in particular crosses.  I have never found any that survived.  They use up the nutrients available in the seed and then die.  I really have quit paying attention to this, but when I first started hybridizing I puzzled over it.  I don't think the albinos result from anything you did, but are just the results of certain genes in combination.

Subject: [iris-species] LA cross question

Unlike those who have experienced their first bloommmm (yes Denis, I'm jealous), I'm looking farther afield (so to speak). 
 
I made several crosses with Louisiana irises last year involving a 'dwarf' I. fulva and more modern hybrids (the names of which escapes me, but came with a 2005 Aitken's order). 
 
I had no expectations.  Of ten crosses, I got two takes.  One pod gave three seeds and the second pod over thirty.
 
The first pod has had no germination thus far, the second pod has ten.  I'll be keeping them going for two years.
 
Here is the item for I would like input.  Of the ten that have germinated, only two have chlorophyll.  The only chemical I have used in the garden over the last five years has been Cygon, so the results are not associated with mutagens (as far as I'm concerned anyway).
 
Has anyone had similar results with LA crosses? 
 
(Denis, could you ask the LA forum for me; I'm having trouble subscribing)
 
 
Regards,
 
Sandy Ives in Ottawa (who has seen I. reticulata in his garden on March 15th... just not this year)
