beckygardener said:I just am rather stumped as to where those double genes came from. If I could find even one double ancestor, then I could say ... that's where it came from!
Are doubles common even from non-doubling parents/grandparents? Is it a mutation that causes the doubling that might just show up in a non-doubling gene pool?
Becky, there is a catch-22 to doubles. A plant may have the necessary genetic make-up to show doubling but the amount of doubling can be variable. A cultivar might only have 95% of its flowers double. Then the hybridizer would probably register it as a double. Or a cultivar may only have 10% of its flowers double or it might have no flowers double most years and some flowers double every few years. The hybridizer would probably not register that plant as a double but might still register it if it had other characteristics considered to be of sufficient quality to be registered.
Your seedling is from 'Laura Mast' x 'Dragonfly Dawn'.
Some of the ancestry on the pod parent's side.
'Laura Mast' is from ((sdlg × 'Inquire Within') × 'Mysterious Eyes') × ('Cyber Zone' × 'Seeking Attention').
'Mysterious Eyes' is from ('Druid's Chant' × 'Magnificent Rainbow') × ('Wineberry Candy' × (Tet. 'Exotic Echo' × Tet. 'Priscilla's Rainbow')).
Now lets look at the ancestry on the pollen parent's side
'Dragonfly Dawn' is from 'Solar Blue Angel' × 'Jamaican Love'.
'Solar Blue Angel' is from 'Inky Fingers' × 'Celestial Eyes'.
'Celestial Eyes' is from 'Blue-eyed Guy' × (('Gerda Brooker' × 'Papilion') × (Tet. 'Exotic Echo' × sdlg)).
Notice that we have 'Exotic Echo' in the ancestry of both parents of your seedling. 'Exotic Echo' is not registered as a double. However, it often doubles on rebloom. If we look at its registered offspring there are a total of 86. Of those, 20 are registered as doubles.
We can
probably attribute the doubling of your seedling to inheriting a doubling tendency from 'Exotic Echo'. If I wanted to be more certain I would trace back all the ancestors and check each one for the number of doubles in its registered offspring.
I would be very interested in knowing if the other buds on the scape also open to be double flowers and also very interested in knowing how many of the buds on its next scape are double and when that scape appears.
