True Potato Seed

- This clip is from volume 4 of The Science of Propagation series. True Potato Seed(TPS) is harvested from the fruit of the potato called a "potato apple". This seed can be cleaned, dried and then planted to develop new kinds of potatoes. By growing potatoes from TPS we can increase genetic diversity and develop disease resistant varieties. The Irish Potato Famine was mainly cuased by lack of genetic variation within the potato crops being grown in Ireland at that time(1800's).
Thank you, that's wonderful to know.
Good video
I never dry my potato (tps) seed in the sun. I dry them in the shade and they grow fine. I'd be afraid that drying in the sun could cause damage. I don't know for sure but I've never dried any seeds in the sun and I have never had bad seeds.
The plants are often harvested before the fruit forms. In my garden, the flowers are often eaten at night (skunks, woodchucks, raccoons) so the fruit doesn't develop. I've also seen plants die down before the fruit can mature. Vigorous, mature plants should flower and produce fruit, but you have to look underneath the leaves.
There are corporations who claim to own patent rights on certain genes, which would make it illegal to propagate, in any way or form, plants which contain these patented genes. I'm all for "rules and regulations" that protect individual property rights, including the hard work and creativity of plant breeders, but the concept of gene-ownership is simply tyranical. Can a corporation own mother nature? If so then only corporatons, not idividuals, can own property.
Wonderful video. Can you tell me why I seldom see potato apples on potato plants?
Thank you for a great video.
The video is semi- correct. There was a potato blight but what about the rest of the countries produce? There were shiploads of other goods exported under armed guard. The British administration were responsible for the deaths if the Irish duit these years and not the simple potato. Those years should be renamed 'the Irish Holocaust'.
👍
Given that potato flowers self-pollinate, unless you are intentionally cross breeding using different strains, disease resistance with propagating by true seed probably has more to do with the seeds being physically separate from the soil rather than maintaining genetic diversity.
+nitroboy756 The seed will need to go in the soil anyways, genetic diversity is a much better defense against disease than having the seeds stay out of the dirt for a bit longer.
If you're propagating using tubers only your inventory will only last a few generations until crop failure due to soil borne disease. Because tubers are in contact with the soil, there is carryover when you pull them and then replant them. True seeds avoid this carryover because they remain aseptically encapsulated and separate from the soil until sown. None of this has anything to do with genetic diversity.
But back to my original point. There is little genetic variation to be had with self pollinating flowers anyway. The offspring are more or less clones of the mother plant.
nitroboy756 More or less clones? uh no. They are not clones. Potatoes with purple flesh have been produced from true potato seeds, they are definitely not clones.
You're not going to get any purple potatoes (or extra disease resistance) by passively saving and sowing true seed from your yukon gold crop.
nitroboy756 Well, it happened. Don't act like you know the absolute truth on things you don't understand too well.
Isn't somebody trying to make this illegal? Individual propagating?
The seeds will dry in 2 or 3 hours on a warm day. I spread out the seeds and left them in the greenhouse overnight. Potato apples are not edible. Potato apples are poisonous, like other green parts of the potato.
