That is an interesting idea. Corn has 10 pairs of chromosomes. I wonder if you can tell for each pair, which one came from which parent? But then again, it shouldn't matter. As long as a set of 10, and its complement, both produce viable individuals, their offspring should be identical to the desired hybrid.
Now we just must not tell this to the Chinese...

Genomic imprinting is specifically to do with DNA that behaves differently depending on whether it's paternal or maternal. The most famous example of this "in real life" is Prader-Willi syndrome (mentioned in the imprinting article), in which the same genetic defect causes one of two radically different pathologies, depending on whether it came from the mother or father. I think it's worth noting here that plant genetics is vastly more complex in basically every way than animal genetics.
