Cactus Hybridization

Recommended Posts

Lemaireocereus synonym of Stenocereus

Fair enough but the first time around he was more specific about the species; geometrizans x pruinosus, which given the second listing makes me question the whole thing.

I've been leaning towards Polaskia as well, but more likely chichipe.

"Barriers to reproductive isolation are poorly developed in cacti ,Hence both interspecific and intergeneric hybridisation.

"Harrisa jusbertii is found in collections and is believed to be an inter-generic hybrid of H. pomanensis and Echinopsis eyriesii."

http://cactiguide.co...?genus=Harrisia

"x Ferobergia, a hybrid between two cacti of the genus Ferocactus and of the genus Leuchtembergia.
The more distant the relation between the two genera, the greater the difficulty of intergeneric hybridisation. Genera that generate intergeneric hybrid are always genetically related members of the same taxonomic Tribe . Many intergeneric hybrids are infertile."

http://cactus-art.biz/note-book/Dictionary/Dictionary_I/dictionary_intergeneric.htm

"Hildewimtera aureispina (now renamed Cleistocactus winterii) is an old species that can be hybridized with various cactus of several different genus (Among them: Echinopsis, Lobivia, Matucana, etc) giving rise to some intergeneric hybrids."

here is a supposed cross between a Toumeya papyracantha and an Echinocereus knippelianus:
if it is then its very remarkable, although it is not proven and does resemble, if anything, a monstrose mammillaria:

lophophora x ariocarpus, 'Ariophora':

some neat stuff here, including a Pilosocereus palmeri x Disocactus speciosus:

^^
this is about as far apart as i can find, so its possible to cross a diurnal flowering jungle epiphyte: http://betula.br.fgov.be/RESEARCH/COLLECTIONS/LIVING/LIVCOL/img_medium/6005000030303_19392203_m.jpg
with a nocturnal-flowering columnar:

very interesting.
there is also lophophora x turbinicarpus but this can be expected as the two are quite closely related.

Chamaecereus (Echinopsis) sylvestrii with a Lobivia minuta,

Cereus x hylocereus (dragon)

last season I used Eg's cement method to self pollinate cleistocactus strausii.

I also attempted to x cleistocactus strausii with a common Red Epiphyllum-(which I understand is probably an interspecific hybrid), as they were both flowering at the same time.

Both seed lots grew successfully, initially I assumed that the epi x cleist was highly unlikely, & I'd probably just self pollinated the cleist (contaminated). The epi's fruit/seed (opposite x) failed to germinate.

The cliest seed is slow growing, but the self pollinated seed are the smallest & weakest, whereas the cliest x epi, are strong/vigorous, they diffidently appear to have separate genetics, & the links above indicate that the epi x cliest was probably successful.

At the moment I'm x-ing trichocereus grandiflorus (white) with cleistocactus strausii, & visa versa.

My red epi & Schlumbergera-(It is an interspecific hybrid between S. truncata and S. russelliana) has masses of buds about to open...so the pollen of these & the 1's above will be saved & x.

I know the forums is slower nowadays, but this thread is awesome

 

I am very interested in attempting inter-generic hybrids, so by the begining of autumn, october or so, I will hopefully have results to tell. failure or not..

pretty cool yeah, I am almost sure I have seen this listed as one of the multiple monstrosa forms of mammilaria bpsacana, (did I own one too? I am not sure)  so I am inclined to buy the theory this is a mammilaria monstrosa and not a inter-generic hybrid. 

 

I was lucky to get my hands on a couple more ferbergias in a cool trade with a small but awesome ferocactus breeder , I already have one that is importing a more and more twisting and spine habit, also developing an obvious central, both Fero traits. 

 

I could be a victim of falling-in-love with my own plant, but I think my ferobergia albeit a relative small is one of the prettiest ones I have seen. The pics doesnt do justice to such plant... it propably has to be a video or something, lol.. 

 

So I have caught the ferocactus and ferobergia flu this year, and as I have a fero viridescens which is flowering I thought I ought to give it a try, especially as I learnt there is also a Ferenocactus  (Fero x Stenocactus  inter-generic) 

 

Ferocactus fordii also seems to be the deal for such shit.

 

Also some astrophytum seem to be semi- compatible with leuchtenbergia, and also thelocactus is also mentioned as well as echinocactus grusonii and coryphantha elephadidens.. 

 

so we got fero, steno, leuchtenbergia, thelocactus, echinocactus grusonii , coryphantha elephadidens.. 

 

in any case, I have started freezing pollen , first time I do that. and since I did that, I also took some hildewintera cv alpha pollen to attempt to pollinate a spineless scop budding in my roof maybe, even though I am not lucky with tricho flowers and fruits - maybe my cacti are starving (root bound + rather small pots) , zelly would know I guess... 

 

my first attempt with 2 flowers of ferocactus viridescens is over, I made 6 attempts during ~2 days of flowering... I tried 2 forms of steno (lamellosus and cf crispatus) and a fresh astro ornatum nudum which came handy and which I also froze pollen of.... but another pair of flowers is coming soon.. boy I wish I had some leuchtenbergia pollen! 

 

zelly do you have any?  

 

shitty thing is ferocacti seeds/fruits take forever to mature, I am told 1 year !??!  amazing especially if you compare with the quite rapid astro or steno ..

leuchtenbergia seedlings from my own Ls  and some arios, some old seed that zelly had sent me - I sent most of it away and sowed what was left recently... I am seeing a hair or something in a couple of them... they just a couple...
