Pollinating Lophophora

Post by gtstcactus »

Hey all,

I have quite a few lophophora in my collection some are self fertile and produce seed without any help from me. Others are not self fertile and require some assistance.

What cacti (non lophophora) can be used to pollinate lophophora? In paticular I'd like to know if there is anything I could use to pollinate my Loph.Diffusa var kohresi.

I've successfully used obregonia dengii to pollinate loph. williamsi. Are there any other cacti that work on lophophora?

did you grow out your l. williamsii seed that was pollinated from obregonia? what was your precess. williamsii is self fertile so its pretty difficult, or at least time consuming, to use it as a mother in hybrids. not that others are not.

l koehresii seems to accept pollen from l. fricii rather easily.

be sure to mark your seeds and grow them out so you can be sure not to muddy the water :)

Now, much of what I have found did not include locality information for specimens used in these crosses nor did they always include whether the specimen chosen was a self-fertile or not.

Also note, there is not much information to be found on how these pollinations occurred. Was the flower emasculated first? Was a donor pollen or mentor pollen utilized? Was a cut style approach used?

Given that often it is possible for a particular phenotype to be dominant over another was the cross carried out further to the f2 or even backcrossed to help bring out the recessive traits or was it just assumed the cross was successful without further breeding of the progeny?
Were the progeny sterile thus making an f2 impossible to make?
