A valid point John and one that I have discussed with Paul Black and
Keith Keppel. One of the primary parts of the definition is the
absence of anthocyanin in the beard and bottom part of standards and
falls. Genisis Project fits this. Keith wanted to see it in bloom
before saying definatly if it was a luminata as he was wondering if
there was some residual anthocyanin giving the darker yellow its
shading. I havn't heard back fronm him on this yet. The original
luminatas were on white ground, this one is on yellow ground. The
same way we have pink and yellow glaciatas and not just white
glaciatas. I'm arguing for genotype as being the decisive factor and
have an ambitious research project underway to corelate genotype
with phenotype with plicatas. Anyone interest in preliminary
results/theories feel free to contact me offlist.
This is similar to the old lumpers versus spliters in species
definition. If we name every nuance of shade, background colour etc,
we will soon be up to our ears in colour names.
