You can research the evolution of polyploidy plants to understand how species of different chromosome values will evolve, cross pollinate, and form unique hybrids of different chromosome counts.
The stacking of more chromosomes generally leads to bigger plants and subsequently larger blooms and fruits. In a lab, scientists have made strawberries with a whooping 64 sets of chromosomes! I think they were just seeing if it could be done, not necessarily looking to commercialize this Frankenstein plant.
