question about Bigeneric hybrids
I've read a fair bit about bigeneric hybrids in which colchicine is used to double up the chromosome number to produce a fertile plant - eg Tritcale,
I was wondering if you had two species from different but related genera both with say 2n=30 and crossed them, the offspring would also be 2n=30.
Does that mean the hybrid would have a good chance of being fertile.
Incidentaly if anyone has images of any of the bigeneric maize hybrids, please post them I'm desperate to know what the ear of a zea/avena cross looks like,
