Pat,
The words of Kevin Walek come back to haunt me!! You may remember Kevin from NCDC. He was one of my mentors, and trained me as a garden judge, instructor, and exhibition judge. Hybridizers feared for Kevin to judge the seedling exhibit at shows, for he had the reputation of being merciless, if not brutal with seedlings. He was good at convincing panels to see it his way, and left a trail of white and yellow ribbons, and worst of all, the simple word "judged."
But on reflection, there is a great deal of merit to his argument. The difference from judging a seedling and a registered cultivar in a show is the points given for that ELUSIVE quality, "distinction." There are enough points in the distinction category to bring a seedling that doesn't show distinction in some way ( not always the bloom, can be the scape, the bloom season, the form, size, etc) down to a score low enough to disqualify it from a purple, blue, red, and sometimes even a yellow ribbon.
So here is the question Kevin would ask us to think about when evaluating a seedling: " In what way does this this particular seedling show distinction from ANY OTHER REGISTERED CULTIVAR currently in commerce?" If you can't give a specific answer, then the score must reflect that. I still ask myself this question when judging seedlings in shows, and also when evaluating my own seedlings. It sounds as if you are already very discriminating when registering. I encourage you to continue that. IMHO, there are far too many nondescript plants already in commerce, as evidenced by the fact that so many disappear from commerce after a few years.
