    New Amphiploid Sundew Genesis

    You’ll find images on the web of a hybrid I created years ago: Drosera rotundifolia x capillaris. The original hybrid is sterile. Through the magic of Colchicine treatment I have created a plant which should now be fruitful and multiply. Last week I harvested and sowed its first seed. They look very good and I anticipate germination will begin soon.

    What does Colchicine do to make the hybrid fertile?

    Thanks. The seed is germinating; the first only six days after sowing. Colchicine treatment caused a decrease in size and vigor which I’m hoping some of these offspring will regain. The first sprouted seedling is growing strongly and looks very healthy, so far.
    This new amphiploid is especially interesting to me because it might prove interfertile with the natural amphiploid D. anglica. It might be possible since my creation and D. anglica are both tetraploid and half D. rotundifolia.

    I have a published article on the web: Colchicine Treatment on Sterile Hybrid Sundews
    CPN Samples
    “Hybrid plants are often sterile because the parent species have different chromosome numbers--as a result the chromosomes from the parents cannot pair compatibly. If such a hybrid has its chromosome number doubled, then the chromosomes are paired with their doubles.”
