Cattleya Walkeriana 'the Chairman' X 'Whopper"

[RJSquirrel]

from SVO 2022 bundle. Starting to get blooms for my hard work .

Beautiful! Happy young plant!

Stunning indeed! Stephen, isn't there some disagreement on the status of 'The Chairman' as a species? I don't care, I'd love to have this plant and bloom it in my collection either way!

Yes, the Chairman has loddigesii in it's background. It's from that whole 'Pendentive' complex that includes well known plants like 'Dayane Wenzel' and 'Estrela da Colina.'

Wow I didn't know that! Is 'Dayane Wenzel' suspected to have loddigesii in it as well?

Yep! There are a bunch of other names from that breeding line that you'd recognize. I can't remember the others right now though.

'Dayane Wenzel' and 'Estrela da Colina' is really more with the ancestral 'Orchidglade'. These don't pass the dolosa lip and yellowish white colored side lobes like the 'Pendentive' progeny. Real Orchidglade progeny like Estrela, Dayane and others are so distinctive and still within C. walkeriana parameters.

The morphology you discuss is correct in that they appear like walkeriana (as does 'Orchidglade') but my 'Estrela' x sib progeny bloom in the spring instead of the fall. They don't have the same aversion to blooming with persistent nightlight like pure walkeriana do either, so there are certainly some legacy influences from loddigesii. Though I have to admit, the legacy influences seem pretty positive, but hybrid vigor will do that!

Yes, the first walkeriana DNA test used 'Pendentive' lines to compare with x dolosa and (surprise, surprise) they found no genetic difference. The study was redone with appropriate comparisons with more useful results that were only semi-conclusive.

Yes on blooming times. The original 'Orchidglade' is still quite a genetic mystery. What I mean is the morphology of the plants from "Orchidglade" vs. the plants from the 'Pendentive' line. Also in reality all comes from a self of the original "Orchidglade". 'Estrela da Colina', 'Dayane Wenzel' and 'Rosa Silvestre' are the result of a wild tipo walkeriana crossed with an 'Orchidglade' that in reality was a self from the original plant, but different to the 'Pendentive' clone. Plants resulting from Pendentive tend to pass a very distinctive color and shape to the lip and side lobes even a few generations later.

In the walkeriana DNA test paper you can see there are a few tested plants named "Orchidglade" from different sources. If I remember well all having DNA differences among them.

There are two papers now!
