Yes, I was thinking that at the time, but didn't write it. I would have 
thought that the 40 chromosome sibes would need some human assistance. Like 
removing the anthers from the PCI's (PCN's .. whatever) and placing the 
siberian pollen on the stigma of the PCI.
How willingly would they cross without that intervention?
Cheers, Jan
