Re: Phal Orchid World remade from start as 4N- amabilis issu

Making newer versions of old but good hybrids with 4x ploidy was once a goal of mine. I developed a few 4x species populations such as P. venosa 4x (red mahogany breeding) and some 4x P. amboinensis but then got side tracked with Cactus genetics and taxonomy. I'm back at breeding Phals again due to ...

I have not seen the plant or counted it but Rob is probably right about it likely being 2x.

Re: JimL, why don't u grow 4N phals?

Actually, flow cytometry is not easier than counting by chromosomes. Chromosome work is quite easy if you have the equipment and a little training. Just not many people that care enough to go that far with it. In general, species plants are 2x while many larger hybrids are 4x, other than that you ar...

Re: Golden Sands 'Canary'-where do we go from here?

Well, have at it!! That horse was beaten so severely by major breeders in the early 60s through the 70s that you would think that people would have learned something from it. It seems that every new generation has to make their own mistakes but in hybridizing, it really doesn't matter what silly thi...

Re: Pollen viability in keiki paste induced flowerings?

Sorry, didn't see this earlier (again). The results of kieki paste on flower morphology could also be due, in part, to methylation state but I didn't test for that. What I did find was aberrant chromosome counts in pollen meiosis. I also found chromosome deletions and aneuploidy in the developing st...

Re: Speciosa 'C#1' x mariae

A number of plants with similar ancestry have been called P. speciosa in European orchid circles because of the colored lip. The solid red forms of this hybrid and some with P. sumatrana are about as close as anyone will come to a plant that looks like P. speciosa since the species doesn't exist as ...

Re: Coerulea breeding updates

A breeding result that yielded some interesting data was a cross of an "early" indigo form and a coerulea form. I raised a number of these and most were like the lighter coerulea form or only slightly darker. One plant however was as dark as any of the line bred "indigo" forms. This indicates that t...

Re: Pollen viability in keiki paste induced flowerings?

I'm sorry that I didn't see this when it was posted. The correct answer is that phytohormones in keiki paste do cause mutations and I would not use pollen from flowers obtained in this manner.

Re: Harlequins

Sorry I'm slow in seeing this. I'm not very familiar with Yu Pin Panda and have no way to look up its ancestry at present. I know that Brother Sara Gold is a good breeding plant. I would try the cross with Brother Sara Gold as the pollen parent.

Re: Coerulea breeding updates

Rob, if the diploid white P. aphrodite used carries color genes for petal color that are masked by a mutation completely unrelated to coerulea mutations then breeding them to coerulea forms may not produce many coerulea forms no matter how many generations you go. Catt coerulea breeding with matings...

Re: Coerulea breeding updates

Rob, don't give up on the phal genetics so quickly. We face the same problems in coerulea Catts. There are different coerulea lines which have quite different mutations and whites that often give back pinks. The secret is to take the resulting progeny from breeding white diploid phals to darkly pigm...

Re: 4n Phal Purple Martin

Induced tetraploidy in Phals is not always associated with decreased fertility. Often, with the poor treatment protocols available, so much damage was done to the plant that they would not breed and in addition, many were actually converted aneuploids not tetraploids because the original plant mater...

Re: Phal gigantea 4N?

Mark Rose and others were reputed to have converted Phal. gigantea to 4x but to my knowledge, none of the plants have actually been confirmed as 4x. A few years ago at least three individuals that purchased Mark's plants approached me to get a count done. None of them actually followed through so, e...

Re: Genetics Question - var "flava"

The above answer is great but it is slightly more complicated than that. Yellow can also be from nuclear DNA sources. Generally the flower in a "normal" plant has both yellow and "pink" pigments and a "flava" plant has a genetic defect that removes most or all of the "pink" pigment production. All f...

Re: hieroglyphica 'Super Size'

I agree and I indicated that the plant could just be a fine form of the species. I would say however that many "collected" plants in culture turn out not to be wild collected and additionally, there is a line of thought in taxonomy that suggests that P. hieroglyphica is the result of hybridization. ...
