Does anyone know if variegated cactus can pass on the trait through seeds, even if it has to be pollinated by another variegated cactus?

Yes the trait can be passed on and generally the offspring will have varying degrees of variegation. This can differ from species to species but as a general rule the trait is passed on to some degree in the offspring.

It does not need both parents to be have the trait, one is enough to pass it on. I have had greater success (If only having one) when the variegated plant is the father.

Thanks, thats good to know. I've been working on getting a number of variegated cacti, for breeding and refining.

Yes, they do - sometimes.
An easy way to obtain variegated cacti is to sow japanese astrophytum cultivars.
Or you may cross pollinate some of your cacti - for example lobivia and chamaecereus.
Then sow the seeds and graft everything that looks differently or odd.
May be you get something like this:

That's pretty good, it has me thinking of new types of hybrids to try.

I have 2 floweing size of varigated asterias (kabuto nishiki).
One is grafted and the other is own-rooted.
When you used a varigated plant as the father, you will get high percentage of varigated seedlings.

The photo is 1 year old asterias seedlings, sown seeds on 28th August 2010.
Since my target was red flower, I used varigated asterias as mother and red flowering asterias as father.
Around 30% of seedlings were varigated with various degrees of varigation.
I selected 25 seedlings for own-rooted plants and repotted last September.

I think 2 seedlings of right end on 3rd row from top are good degree of varigation for own-rooted plant.

Well, I have an update on my hunt for variegated Astrophytums. 3 of the massive batches of seeds have managed to cough up a total of 4 variegated astros. Not entirely sure what kind they are going to end up as 2 were from batches of myriostigma, and 2 came from hybrids that had at least one asterias parent. I grafted all 4, and they have been growing for a couple of months now, the variegation showing up nicely in some of them. Once they have matured and are producing seed of their own, I'll have a go at producing some own roots variegates.

I grafted 10 varigated young Astrophytum seedlings.
Although this spring has been quite cool, they have just sarted to grow.
1. varigated asterias x super kabuto (Mother is a varigated cactus.)


2. capricorne v niveum x super kabuto (Parents are not varigated cacti.)

Ha, those are awesome Hana! I really like the spines on the capricorne v niveum x super kabuto. Is the pink/red from stress of grafting, or is that part of the variegation?

I think the color of spines is normal color of new spines.
They will turn to darker color very soon.

I meant the pink/red colour of the body. I have one of my variegated cacti turning a little pink but only at the top of only 1 tubercle. I'll shoot a picture of it later.

See the pinkish colouration at the top of this one?
This picture doesn't show it as good because I had low light at the time.

I think pinkish color is the part of variegation.
Own root seedlings show also same color and so it is not related grafting.

Niveum x super kabuto is not true variegation.
It comes from the stress of hybridization.
Whey you corssed differnet flower color Astrophytums, it happens with quite high persentage.
Niveum flower is yellow and super kabuto is yellow petals and orange throat.
