Re: Re: Species Fertility

 

All Oncos are believed to be self-incompatible. A single clone is notÂfertile when selfed, but any two Onco clones are interfertile. All the species are diploid and readily produce fertile hybrids when crossed. I've personally tried selfing paradoxa, back when it was the only Onco I had, with no success. It has since happily hybridized with other species.

It looks like the degree of incompatibility may vary with relatedness. This study found a higher fruit set (and seed per fruit count) hand-crossing between two populations of the same species versus crossing within a single population.

That is good to know.

Do you have some specific species examples? Fertility between clones
of same species but not with self?

The dozens of Oncocyclus species are largely not self-compatible.

Are there any bearded species that have self infertility?
