Notes: Tetraploid Aspen Production Using Unreduced Pollen from Triploid Males
Unreduced pollen from a triploid Populus tremuloides male was used to pollinate a diploid P. tremuloides female. One putative tetraploid was recovered. When this putative tetraploid flowered, pollen from it was applied to a diploid female. All resulting seedlings were checked and thirty-nine of them were found to have triploid counts. Obtaining triploid counts on a majority of the seedlings confirmed the tetraploid nature of the male parent and the usefulness of the unreduced pollen grain technique to produce tetraploids.
