Re: Re: Tectorum X bearded update

I'm thinking about how the tectorum x bearded as compared with arilbreds.
First, over the last 50 years, the arilbreds have been selected toward being more like aril iris, while they have been selected toward surviving more like TBs.  Remarkable progress has been made, though there is still more progress to look forward to.
It is possible that the recessive white gene in bearded iris will be masked by a gene in tectorum, even white tectorum.  To get white from two recessive white genes from two different species is possible, but not certain.  Both genes must stop the pigment production at the same step.  There are examples of it working, and of it not working, in other genera.
You would be more likely to get a white if you could use a dominat white.  This is because the dominant white actively blocks the production of a pigment.  Recessive white only lacks a step in pigment production.
Actually, the gene I'm thinking of isn't truely a dominant white.  It is a dominant non-purple.  It is an anthocyanin blocker.  There is a dominant aemena also, isn't there?  That could also give something different from solid purple.
Good luck with your breeding.  I want to get into breeding tectorum x bearded, but I am commited to getting lycopene pink in arilbreds first.  And that could take a lifetime.  Others have tried and failed.
