Thanks for sharing, Robin. I have been reading up on plicata genetics recently and I think Chuck Chapman is close to the mark with his observations and hypotheses about plicatas and their relatives (luminatas and glaciatas):

If he is right about broken colours in this instance, then your cross makes sense - all the seedlings will be in the plicata group (plicatas, luminatas, luminata-pliacatas and the odd glaciata). Depending on how many copies of the plicata gene 'Ballet Performance' has, the odds of producing a broken colour (if Chuck is right) from should be non-zero as long as BP does not have four copies of the pl gene (since then you cannot get the pl pla pla plu or pl plu plu pla combinations hypothesised as the cause of broken colour).
Of course, that assumes that broken colour is solely controlled by the combination of plicata, luminata and glaciata genes.
#9 is intriguing. Does it have any anthocyanin on it at all? I'd hold on to it for a bit, just in case it's a glaciata.
#14 looks like it
might be a luminata-plicata, although knowing exactly what combination of pl and plu genes it carries can't be determined without test crosses.
