An investigation of its interspecific hybrid progeny found that the triploid progeny had higher yields and better overall performance than did the diploid or tetraploid progeny7. Therefore, research into ploidy levels can aid taxonomic and evolutionary studies, and may accelerate the breed- ing process...
