If they were inherited independently of one another they could expect around 6% colored + 3 spurred. 0.1% means that the 2 genes are very, very close to each other on the chromosome, making it exceedingly difficult to breed. Hats off to them for having the patience to do that!

I'm not sure about mendelian laws of inheritance when it comes to three spurs. The breeder was also telling me that Manjushage will give three spurs to about 5-10% of the offspring regardless of whether it's crossed with a normal shaped flower plant, selfed, or crossed with another manjushage....If i remember correctly, a recessive trait, when selfed, should result in a much higher percentage, if not 100%, of the offspring with the recessive trait, no?

Interesting. The frequencies you gave earlier sounded mendelian, but this clearly is not... Normally yes, if you self a plant with a recessive trait or cross to another recessive you should get 100% recessive offspring, because the parents must have 2 copies of the recessive form of the allele in order to express the recessive trait. Sounds like there may be more than 1 gene involved in number of spurs, or an interation between genes. Genetics is so fascinating! I wish there was more known about inheritance in orchids, and I'm especially curious about this case.

Very nice orchids and blooms Hakumin.
I would like to ask, does common Neo blooms frequently? How many times a year? Do they requires Vanda light level?
Thanks again for sharing.

10 to 15 years with no blooms??? Wow, that person was patient! I would have ditched it after max 5 years...
The 4 months was just meant to say that I have no hindsight, yet, on whether my culture is good enough to see blooms, since I haven't gone through a blooming season with them yet. Things are as they are this winter, and if they don't bloom or not well, I'll tweak my culture next winter. Temperature diffference is probably the problem point if their is one, there's less than 10f difference between night and day.

Camille,
10 F degree winter day/night difference just gives you a much better chance and is not always necessary. Some Neo varieties are finicky others not.

The likelihood and frequency that a Neo will bloom depends on variety. Some are more likely to bloom multiple times a year, others are more likely to skip a year or two between blooms.
That said, you did say common Neos. For the most part if you grow the more common varieties of Neos by giving it a full winter rest for the entire winter, in most likelihood, it will bloom once a year in the summer.
Blooming twice a year in these conditions is also not unheard of, though not incredibly common. However depending on your cultural habits and environment, and especially if you deviate from this "standard" approach, some neos can bloom up to 3 times a year, although each subsequent blooming won't be quite as floriferous as the last if that happens.
As for light level, quite honestly, Neos were the first orchids I ever grew and there are the main orchids that I grow. Unfortunately since I have never attempted to grow other Vandas, I cannot say what light level neos grow at in comparison to those.

Lovely plants, thanks for sharing. I do really like the three spurred plants.

What does Koshi-fu Mean wrt N Shingetsu?
This question for the op, Hakumin.
The internet was no help.

Koshifu 腰斑, is a type of tora-fu variegation where primarily the base of the leaf is variegated. Either the entire stem area and the leaf sheathes like this, or just a small portion of each leaf surrounding the tsuke like this.
