N2  - Expression of gametophytic apomixis in grasses is restricted to polyploid plants. In our effort to transfer apomixis from diplosporous tetraploid Tripsacum (2n = 4x = 72) into maize (2n = 20) through conventional backcrosses, we produced polyhaploid plants combining one complete set of chromosomes from each genus, These polyhaploid plants were totally male sterile, By contrast, viable seeds were produced apomictically when they were pollinated using maize, Apomictic reproduction in such polyhaploids, which show a diploid-like chromosomal complement, suggests that diplosporous apomixis and polyploidy are not totally linked and that diploid crops such as maize might reproduce apomictically
