56-06-05: a new yellow climber.
I've mentioned the Moore Wichurana breeder 0-47-19 several times before, and I thought I should show some of the work thats coming out of it. I use it with the goal of improving disease resistance, plus it often brings added vigor to a breeding line, and the seedlings are generally very easily rooted from cuttings.
Illustrated here is 56-06-05, a cross of 'Joycie' X (0-47-19 X 'The Yeoman')*. The pollen parent, listed as 42-03-01, is a vigorous, once-blooming climber with glossy, disease free foliage and clusters of butter yellow blooms at most every leaf axil along the arching canes. 42-03-01 rarely sets seed and its pollen is only marginally fertile, but I have persisted in getting seedlings from it since it is an opportunity for improvement of the health and vigor of the breeding line. 56-06-05, the yellow seedling pictured here, is the first seedling from 42-03-01 worth mentioning so far, and I hope it passes on its health and vigor to another generation.
56-06-05 is also a vigorous climbing plant, with bright grass green glossy foliage that so far has had no problems with disease. Blooms are fully double and about 2.5 inches across, with a pleasant, but mild Tea (phenolic) scent that often accompanies yellows. It took two years for this seedling to mature enough to start flowering, which is a reminder that sometimes its worth keeping an interesting seedling, even though it may not bloom the first (or second!) year. I'm much more inclined to keep un-bloomed seedlings from unconventional breeding lines in the hopes that they may have traits of value in furthering the line. 56-06-05 appears to be fertile, as it has produced seed hips with several pollens. I won't be able to comment on fertility till next Spring when I find out if these seeds germinate or not.
Note to breeders: I have a couple plants of 42-03-01, the pollen parent of the seedling above, if anyone is interested in working with this seedling.
* 42-03-01 is listed as 0-47-19 X 'The Yeoman', although I have reason to doubt the parentage. I suspect this seedling may in fact be a 0-47-19 X 'Out of Yesteryear' seedling that got mislabeled, since it bears a strong resemblance to several seedlings from the latter cross. It is also suspicious that a cross using 'The Yeoman' would produce anything in yellow, whereas 'Out of Yesteryear' easily could.
