Thanks for the answer Sharon. I know you don't breed TB's but you are 
our acknowledged genetics expert. The fault in my thinking was that a 
luminata would have pl-lu,pl-lu,pl-lu,pl-lu,
but Jeff tells me that there can actually be a mixture of pl-lu and pl 
at the plicata locus, in 'fancies', as neither is dominant. 
Next question - is there a difference in appearance between a 'fancy' 
with say - 1 pl-lu gene and 3 pl, and another cv with 1 pl gene and 3 
pl-lu genes?

Looks as if this will be a 'curiosity' cross for 1999, and a project for 
the next few years. 
The problem with zonals and luminatas is compounded by catalogues which 
label irises as one or the other, or neither. (same with glaciatas) I 
have seen CYCLES called a luminata in a catalogue, but would call it a 
zonal myself. Anyone on friendly terms with Keith Keppel, and could ask 
him these difficult questions???

Cheers, Jan Clark, in Australia, where KK visited and if I had a 'pushy' 
nature I could have gone to Barry Blyth's nursery and asked him all 
these questions myself!
