In this instance, if such occurs with any desirable trait, then I can backcross any reblooming, dark scaped F2 seedling to any of these F1 seedlings. They have no obvious, serious flaws, so a backcross can be considered, and all the genes I want to see expressed are present in all these F1 seedlings. Further, both the F1 x F1 sib matings and the F2 x F1 backcross can reveal any hidden deleterious or undesirable genes that may be lurking in the line unseen, and that too is valuable information from a breeding standpoint. As well, a backcross may even concentrate the desired traits, both the rebloom and dark scape traits as well as the plant habit traits that are also very impressive.
So back to this seedling - There are some good traits here and the traits I don't like are really more about personal preference than an actual defect, so this is one of those projects where I am just not satisfied with this first generation result and want to keep working to get to a plant that is more what I want and what I want to introduce.
Many people are not bothered by the rolled inward or 'canoed' petals, but it irritates me, and that is just a personal preference. It is no reflection on anyone who likes that or grows or introduces plants with it, but I am obsessed with very open, very flat flowers - blame Richard Norris and his wonderfully flat Substantial Evidence family line! smile emoticon
