Re: sdlg L44 (OGB)

Roberto, Usually one does not need to embryo-culture seeds of tetraploid OGBs. Their germination statistics are usually satisfactory. One usually does embryo-culture of seeds which are from what we call 'odd crosses' meaning these seeds are presumed to be difficult to germinate, possibly by the production of no embryos, malformed embryos, etc. because of the imbalanced cross. When embryo-culturing, if you find that a particular cross has mostly good embryos you may have a chance that the remainder of the seeds will germinate normally. I would recommend that those odd crosses which have resulted in normal embryo formation should be colchicined to see what their counts would be. Your seedlings from the L44 cross seem to be consistently good. Congratulations.
 
Your English is quite understandable. I wish I knew Italian as well as you do English. I would be very happy. When I write to my Italian aunt in Reggio Calabria (RC) Italy,  I write in English and she has someone translate my letter for her.

Subject: Re: [iris-photos] sdlg L44 (OGB)

I have twelve seedlings of this cross and I am cultivating for three years.
Last year anybody was blooming , but a late frost has stopped the growth of the stalks.
This year  have bloomed 6 and everybody are similar to L44-1, except L44-2 almost white (effect of a recessive antocianine inhibitor ?).
L44-2 is also the best increaser, with numerous fans and 3 buds for stem.
I tried embryoculture two years ago, on TB seeds, with discreet success, even if finally has saved only one sdlg of 6.
I retried last year on AB seeds , with some modification into the procedure.
But something has not worked and after six months the embryos are still like embalmed !
I hope that my English is comprehensible, I done one's best.
Attached L44-5, the large spot of Lancer would seem dominant !

Roberto,

            Both of these seedlings are wonderful.  How do they grow?  Are they good increasers?  How many buds?

Thanks Roberto,
 
I have pods, included several on BRONZE FALCON, that may missing embryos.  Do you embryo culture your seeds?  I was very interested to see the DESERT DIAMOND seedlings.  I've manage to get seedling on TBs with the pollen from DD, but never on an arilbred.  Nor has it ever set a pod for me.
