Pollen from the three diploid species and irradiated pollen from American elm were used in crosses to induce polyhaploidy in tetraploid American elm. The resulting seedlings were tetraploid and morphologically typical of American elm, presumably as a consequence of self-fertilization. Forest Sci. 16: 137-138.
