Cactus hybrids
Just curious if there's a list of cacti species that can be hybridized. For instance, can you cross an echinocereus with a mammillaria? Any help is greatly appreciated.
Re: Cactus hybrids
I can only recall Leuchtenbergia with Ferocactus, known as Ferobergia.
And maybe you can add chimearas to this, which is a result of (among other?) grafting.

Re: Cactus hybrids
Many cacti will hybridise freely, even with different genera, although many won't. Some hybrids may be possible, but will occur rarely or with a poor chance of success.
A naturally occurring hybrid between different genera is Pacherocactus orcuttii, a cross between Pachycereus pringlei and Bergerocactus emoryi.
In general, crosses are more likely the more closely species are related to each other. For example, many hybrids have been produced amongst the related species of Echinopsis / Lobivia / Trichocereus, but you would almost certainly struggle to cross an Ariocarpus with a Pereskia, an Austroactus with Carnegia or Mammillaria with Rebutia.
Cladograms or Phylogenetic trees give some clues about species which may be close enough to hybridise - there's plenty of scope for experimentation.

Re: Cactus hybrids
I wondered the same thing and have been following this since you posted it. Today I found a pretty good phylogenetic tree of Cactaceae:
https://bsapubs.onlinelibrary.wiley.com ... jb.1000129
They didn't attempt to make a tree for the entire family, but the most comprehensive is on page 52. Doesn't say what will hybridize, but allows for us to make educated guesses

Re: Cactus hybrids
It does not surprise me that Aztekium, Geohintonia, and Astrophytum are so close to one another. I find them very similar in care needs as well.Shane wrote: ↑Thu Apr 16, 2020 11:07 pm I wondered the same thing and have been following this since you posted it.

Re: Cactus hybrids
Concerning Mammillaria only, do they hybridize (between species)?
I have several Mammillarias in bloom now, and many native bees are visiting them.
I would like to harvest "pure" seeds, definitely I dont want hybrids. As I don't see too many hybrids in the genus, I'm assuming they will (mostly) fail to hybridize, but I'm not sure.
Perhaps I should be concerned only with species within the same Series (Within Ancistracanthae, for example). Am I close to the right answer?
Thanks in advance for any input.

Re: Cactus hybrids
I am quite certain the red spined Mamm carmenae is a hybrid. Possibly with subducta?? Spines a quite stiff. Still very beautiful and worth growing..mmcavall wrote: ↑Thu Jun 17, 2021 8:55 pm Concerning Mammillaria only, do they hybridize (between species)?

Re: Cactus hybrids
Mammillaria generally don't readily hybridize with each other. There aren't really many (any?) well documented Mammillaria hybrids out there, which to me is a sign of this. They very easily self pollinate and apparently prefer that to interspecific outcrossing. I think it's a safe bet they will mostly fail to hybridizemmcavall wrote: ↑Thu Jun 17, 2021 8:55 pm Concerning Mammillaria only, do they hybridize (between species)?

It's also important to note here that research is showing Mammillaria is likely not a single genus but several similar looking genera. So a "Mammillaria" isn't necessarily closely related to another "Mammillaria" which would be another barrier to hybridization

Re: Cactus hybrids
I crossed echinocereus poselgeri with the common peanut cactus (echinopsis chamaecereus) and there are fruits with seeds. Echinocereus was used as a mother plant and it's making fruits.
Re: Cactus hybrids
In this case Echinopsis pollen might just been used for stimulation of Echinocereus to self-pollinate. If you grow seedling from those seeds will be clear are these hybrids or pure Echinocereus poselgeri offspring.
If your cacti mess in your job just forget about the job.

Re: Cactus hybrids
Interesting, I'm actually looking into ways to self-pollinate self-incompatible species, do share if you know of any other ways.
Re: Cactus hybrids
Sure. You can try using some nectar (diluted honey) over the stigma of the flower and then apply some pollen from the same plant. Sometimes it works even with fewer seeds crop.
