In several of the newer seedlings, I am seeing what appears to be an alternate representation of the blotch into what looks more like a line than a blotch. Some of the seedlings are still showing a blotch at the base of their petals, however, others are just exhibiting a darker line down the center of their petals without any other evidence of the blotch.
I suspect that this line, through subsequent generations of selective breeding, can be darkened and emphasized. Do you think that it is worth pursuing?!
