No diploid seeds, but I could save you tetraploid seeds this fall. I bet some other folks here could save you seeds also. I often have tubers overwinter. I'm on the east coast of Canada, and can be at minus 25 over winter, but there can be quite abit of snow by that time. Seeds that the wildlife steals and then drops will often come up in strange places. Sometimes I pop them up and move them to a better place. Thanks you very much for the offer, but I prefer diploids atm. I also had cases to save chance seedlings/plants due to some interesting properties.  Wish there are more of of those popping up around. Unfortunately, local weeds are way better adapted then anything people have under cultivation around here. If something manages to survive and compete with weeds, I have tendency already to consider it to have potential. |

Anyone having seeds of diploid potato species to share? Just be aware that you would need to receive seed from someone inside the EU. The EU, like the USA, has very strict import rules for potato material. |

The EU, like the USA, has very strict import rules for potato material. It depends what material are we talking about. Seed potatoes (as potato tubers for planting) is allowed across borders only with phytosanitary certificates. Without it, it is irrelevant if material comes from within or outside of EU. Further more, any kind of vegetative material is forbidden to enter Estonia from anywhere without certificates. On the other hand, seeds of potato wild relative (as true seeds) are not regulated and not explicitly forbidden. I'm looking for true seeds of diploid wild potato relatives that potentially can survive local winters. For anyone that wants to help, feel free to disclose full name on outer surface of envelop. Just inform me when you send it so that I can check/disclose it and prevent unofficial miss-placements. Best, Srdjan |

I have planted two dozen, plus or minus, varieties and variety seems to have little to do with surviving winter.
Planting depth and soil do.
Three years ago I missed near a hole row and they all came up the next spring in a spaced row.
I plant deep, eight inches or more now, in winter it always gets to at least 15 below zero F and usually a lot more.

I was sad last year, because I lost my seed-producing potatoes to weeds, I didn't get any seeds harvested. I didn't manage to save the tubers. So the variety was lost. However... yesterday, I was weeding and found a whole patch of potatoes that survived the winter. Yahoo!!! This year I intend to keep up with weeding, so perhaps they will generate seeds for me. I also planted a row of new seedlings, so no worries, something is likely to produce fresh seeds.

I Also am more interested in diploids right now, but i haven't had much luck with them yet. But i haven't put in much effort either.
Last year i too lost my only plant of M6 the diploid Solanum chacoense. It got accidentally pulled up as a weed. But i noticed it came back this year in that spot! It either came up from root or from seeds that had not germinated. Woo hoo!! I marked it and went to weed around it and found two more!
So that's a good sign.

Chacoense starts tuberizing almost as soon as it emerges and the stolons can be several feet long even on very small plants. Unless it is well contained, once you plant one, you often have it forever.

Is your plan to cross the Sli gene into new domesticated diploid varieties?

To further this discussion, Solanum jamesii has been found to possess freakish tuber freezing tolerance. This is suspected to be coupled with its freakish dormancy mechanism, jamesii tubers have been successfully sprouted after a decade in the fridge.

Is your plan to cross the Sli gene into new domesticated diploid varieties? Not sure whom your question is addressed to. If to me, the answer is no. I find this property to be pointless for potato (actually even unwanted). I'm more interested in trying to pass it through some of bridge species (e.g. S. lycopersicoides) to tomato. And yes, I know that tuber and fruit forming on single plant is contradiction and that there are many issues (e.g. incompatibility and sterility issues) with the idea but I would like to try. I left academia but it looks that motivation to try pointless things did not leave me  |

Good for you; sheer curiosity is a wonderful thing.

Hahaha, it seems we have similar goals. No i actually originally got the chacoense because it was diploid and i also wanted to try wide crosses to get purple flowers into tomato to attract new pollinators. But now i see this variety has white flowers, but many of the domestic diploid potatoes do and will cross with it. And yes i know that it may be too wide and may fail or have serious sterility issues too, but i also wanted to try. Why Then did i choose M6 specifically knowing it has self compatibility? I don't really know, i guess i choose it because it has other good qualities and i knew i would fail a lot growing these potatoes and it just seemed like a good choice so that it could self pollinate And create seeds just in case i did not have any other diploid potato plants. Which i currently do not. So Haha, guess i know myself pretty well.
I Also think it has other qualities which may be good to fold into domestic potatoes, but i know there will be some bitterness to select out.
But, since you asked, yes, i think purple flowers in tomato would help to attract more bee species that prefer the blue spectrum.

I expressed I interest in this species awhile back but i don't remember many other people being interested in it then. Where can i get germplasm for it? Does someone already have some that is willing to share in the future? I'm interested in this species. |

I left academia but it looks that motivation to try pointless things did not leave me OK. Do I understand correctly that there is a hardy potato that MIGHT cross with tomato? Or cross with something else that MIGHT cross with tomato? Do you realize that in this group there are crazies who might try to breed a winter-hardy perennial tomato? You have to be careful what you post here. Perennial tomatoes could destroy Walmart's spring tomato plant sales. And there goes our economy. Think before you post! |
