I know that cross-generic hybrids are possible, though uncommon. I wondered if any of the experts out there could give me any info on how often cross-generic hybrids will take. Also is there some place that will tell me the chromosome counts of different plants.
The reason I ask is the following: I've recently been growing some cherimoyas (annona cherimola) from seed, and I was struck by how much the seedlings look like pawpaw seedlings (asimina Triloba). Since they are both in the Annonocea family I thought that it might be fun to try to cross them.
Since my cherimoyas were sprouted from seed it will likely be several years before I could even attempt this.
