Nice blooming Australis.

Just had a bit of a search and found some photos of Seamew 2n and 4n.
I can certainly see the progression of the bloom, petal and sepal size.

Well, there's a bit of a story here. Usually is when we remake something! When I was a kid, one of the hot orchids was a hybrid between Alexanderi 'Westonbirt' 4n and the diploid Seamew. It was named Sandpiper and the particular variety that I craved was Sandpiper 'Sutherland'. But Cyms have advanced rapidly in the post-Wimber days so after remaking Seamew and viewing the 4n's from a Colchicine treatment, I realized the 4n Seamews were too far off the pace for modern color breeding. So I went no further. In hybridizing, there are always blind alleys to extricate oneself from..... The challenge is to see those blind alleys quickly!

True, however, I'm glad I still have one.....it's growing on me! Not a common one to see in Australia anymore.....

Not the greatest photo, but the Cym. Seamew I obtained last week from the grower who was the first owner....
The plant was originally obtained from from Graham Guest and was part of Andy Easton's flasks treated with Oryzalin.
We will find out if the treatment was successful at some point!
Not the greatest flower count with 3 spikes of 4, 4 and 6. But hopefully another growing season and plenty of love will help it along!

6 n's???
AUSTRALIS.
You are playing around in genetics"where few men have gone before."
Be very careful. Some have come back.

My feeling with 6n’s is that used wisely they will be incredibly useful but used carelessly, they will be a disaster!

Andy - yes, this is from your Oryzalin-treated strain. One or two of the seedlings I have might be 4n, but I haven't measured the stomatal guard cells yet to confirm my suspicion.

sabre - thanks for the suggestions. I only have one 6n on hand and it is not really something I want to use with this plant. For the near future I would be looking at other diploids in my collection, or using it with a 4n and treating the cross to get a few 6ns.

I presume this came from our Oryzalin-treated strain? My initial feeling with the 6n-2n combos is you must be cautious not to sequester anything vital. I'm certainly happy with things like Oscar Garden (Enzan Floss 6n X Cym. pumilum) in that I was not looking for stunning lips, given the nature of its parents. It was however disappointing to lose this lip, Horizon Chateau (EF 6n X Esk Claret 2n) certainly did not express the Esk Claret lip in any of the seedlings we bloomed.

Conceptually, I think it is perfectly OK for Cym hybridizing to proceed on several levels. Commercial, show types, "what if? hybrids etc. I've always made one or two of the third type most years.

Australis, you're going to need a bigger backyard.
Commendable that you're contemplating hybridising with these primaries. My initial thought was don't be in a hurry, think about the direction you're going to pursue, and assemble the building blocks to complement these species derived hybrids. For this particular plant, what comes to mind would be a 6n ploidy plant for starters. And add to that something that further enhances its outstanding labellum. So what would be the candidates? Well obviously the Australian species madidum and suave. Others may be concolours, think Coraki derivitives, and of course those with established bold lips, thinking Esk derivitives.
That's my thinking, I'd like to know what others may think could be useful approaches.
