As an interesting aside. Most likely most, if not all, of the Phrag Walter Schomburgs from the first batch of flasks released by Fritz Schomburg are full polyploid 4N's. The reason is Fritz has a 4N Eric Young, and I sold him the 4N clone Andean Fire 'Michelle Lee' AM/AOS, which he used. The clone Andean Fire 'Michelle Lee' AM/AOS was verified as a probable 4N by guard cell measurements and by its track record as a breeder.
So when 2 clones that are 4N are crossed, the progeny should be mostly 4N. Some of the better Walter Schomburg clones I have seen have been really smooth heavy textured and large flowers. All support the supposition of polyploidy. Most clones that I have tried to set seed with formed seed readily and showed a fair amount of germination, another good sign.
So if Glen Decker or Alfredo Manrique used one of those Walter Schomburgs, then the seedlings of this cross, Phrag Alfredo Manrique will likely be triploids, 3N. Not an ideal situation for breeding on, but when a triploid does breed, the progeny will be an assortment of diploids and a few tetraploids. Those few tetraploids will be great, and possibly be fertile amphidiploids (a useful version of 4N). Onward with the March toward the Phrag with a flower that is as large as a Cattleya and as round as a Phalaenopsis and as red as a Fire Engine.
