Astrophytum cultivar/hybrid - lovers will love it
A. caput-medusae X A. miriostigma?
Re: A. caput-medusae X A. miriostigma?
I did a similar cross-pollination but I got a very different result.
Pollination was carried out in 2011.
Species 1: caput-medusae
Species 2: myriostigma v nudum
Pollen receiver X Pollen supplier
Case A: 1 x 2, it was told all seedlings were captu-medusae in this case and I did not do this case.
Case B: 2 x I, 10 of 3 myriostigma could make fruits but seeds in each fruit were 3~4.
Seeds were sown in 2012.
The germination rate was not good. Just 3 seeds were germinated in total, which have survived.
The photo is one of them. The cactus shows the flecking of caput-medusae, which is 9 cm in diameter.
This hybrid has grown very slowly. I have not seen any flower yet which means they may not be able to make any flowers.

Re: A. caput-medusae X A. miriostigma?
Thank you for sharing your experience Hanazono.
I generally avoid cross-pollination for the purpose of making hybrids, but sometimes it happens naturally (I keep my collection outside and various insects visit in search for nectar). I have also observed that hybrid seedlings, in general, grow much slower than those of the pure species.
Best regards,
Nino

Re: A. caput-medusae X A. miriostigma?
Those look like Astrophytum myriostigma 'Kikko' (=Kitsukou?) to me.
I crossed A. caput-medusae with myriostigma twice last year, all seeds failed to germinate. I did it again this year, but this time one seed germinated. It's about two months old now, but has yet to grow its first tubercle. I did other crosses too, A. myriostigma 'Onzuka' x caput-medusae, A. capricorne x caput-medusae, and A. caput-medusae x 'Onzuka' (from stored Onzuka pollen, there was also capricorne flowering at the same and I did not control for insects). I haven't sowed the seeds yet because I've been waiting for that last caput-medusae fruit to ripen. It's been two months now, and it's plump and red, but I am starting to doubt it will ripen before the winter.

Re: A. caput-medusae X A. miriostigma?
I've been making successful crosses of Astrophytum caput-medusae
not sure of the species it crossed with, for sure not myriostigma
My first one was mystery cross from a batch of pure caput seeds, 2015 I grafted it after a year It grows like crazy on it's own roots
named "Astrotopia" Since then, I have done all kinds of crosses
I mark the seed pods with a red felt pen to signify it's a cross rather than a pure species The seeds are normal looking caput seeds, that are big with small horns The seeds are a mix of selfed and crosses This is a new one I grafted last year If you goggle astrophytum caput-medusae hybrid

You get all kinds of cool looking things
most look different than mine

Sorry, there are no picturse to see?

It is still alive? Very interesting hybrid! If it flowers you could make a nice cultivar!Hanazono wrote: ↑Fri Nov 10, 2023 12:30 am I did a similar cross-pollination but I got a very different result.

Dad: what colour do you want your dragon to be?

G'morning ossy96,
3 hybrids are still alive but I have never seen their flowers yet.It is still alive? Very interesting hybrid! If it flowers you could make a nice cultivar!
