Re: RE: Hyb; Luminata & Zonal

Chuck:
I appreciated your thoughts (below) on luminatas.  If anyone ever figures it
all out, I'd like to know.  Meanwhile, I'll just play around with those weird
"is it a plicata or a luminata?" crossovers 'cause I like the way some of them
look.

  There certainly is a relationship between them But first, What is Clarence?
At first glance for me I would say it's a Wide zonal & amoena. For me a wide
zonal is a zonal with an extra wide zonal spot. Don Spoon claims Clarence is a
luminata & amoena. His cross of Clarence X Mind Reader would give some merit
to that thought.
  Luminata appears to be a combination of 3 glaciata genes and one luminata
gene. I have known for some time that luminata pattern is a heterozygous
genetic combination9 a mix of alleles). When Keith crosses two luminatas he
gets glaciatas and luminatas. Same sort of results reported by many other. If
Luminata was  homozygours (ie four sets of the same allele eg; 4 luminata
alleles) the luminata X luminata would produce all luminata, which is not the
case. Glaciata X luminata does produce glaciata and luminata, the exact ratio
will need some good counts of these results. This strongly suggests that
luminata is one luminata and three glaciata alleles. Glaciata X Luminata ,by
this theory should produce half glaciata and half luminata. Some seedlings are
on the way, some hopefully enough seedlings to give a good count.

  This then leaves the question of what a plant homozygous with luminata gene
would look like. I suspect that it is the zonal. Zonal have been kown to be
related to plicata for many ages, with Bob Schreiner writing an article on
this quite some time ago, 60's or 70's.  Fo me a wide zonal would be one
glaciata gene and three luminata alleles. Thus Clarence could still be a wide
zonal as a wide zonal X luminata would also produce some luminatas. I woulsd
like to see this cross repeated with a count of offspring to get a better idea
of what is going on.

  In the meantime I have about 100plus plicata crosses involving luminata,
zonals and many different combinations to see if I can fill in some of the
gaps in knowledge of plicata genetics.
