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. Well, I got my seed from GRIN, they've got a pretty large collection. Currently I've got three accessions growing, but one of them looks to be on its way out. The other two are by all appearances thriving, and are actively flowering right now and I've got berries set on. So I could tentatively give you some seed this fall if all goes well and you remind me. Since you're in CO, you could always potentially go down to Mesa Verde and collect some yourself. Mesa Verde is the hotspot of collected genetic diversity of S. jamesii. |

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  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! I guess from now on, I'm stuck with crazies  Tomato can be bridged (as indirectly crossed using bridge species) to few non tuberous Solanum species and the other way around. It is for sure not easy job but can be done. Potato and other tuberous Solanum species are more challenging and to my knowledge there are no known exchange of genetic material between potatoes and tomatoes (at least to my knowledge). Also, there seams to be a lot of "it cant be done" attitude and lack of attempts. I have Solanum dulcamare and Solanum septemlobum (non-tuberous species but very distant) surviving my winters. I already plan to try and bridge them to tomatoes. Discovering that potatoes survive winter here triggered me to look in that direction as well. |

 jamesii berries, much smaller than tuberosum on average. |

Is S. jamesii edible or worth to eat? Tubers on pictures are really small...
Interesting species.
I have a S. phooreja edible and hardy here but it never sets fruits.

Both S. jamesii and S. phureja are 2n = 24.
So are S. carolinense and S. elaeagnifolium. It is surprising how hard it is to buy seeds of "common weeds".

The S. Chacoense plant i had started to turn yellow the other day and disappeared, i guess went dormant for the winter? So i dug it up and found at least 5 little potatoes. I kept 2 to try to grow this winter (i May put them in the fridge first for awhile) and put the other 3 back in the ground. Most were white, one was dark. I took the largest dark and white. flic.kr/p/2aE84Q9 20180903_152322 by Andrew Barney, on Flickr |

Well it appears that even so far away east and north of its range, Solanum jamesii can grow and set seed. I am pretty fascinated by the range of tuber colors in what (I think) was one plant.  |

If you plant one, or more, of those tubers of a different color , will they then produce tubers of the same color?
I buried all my potato berries but if next year I decide to try to save and plant actual seeds, is there a special process?
From those little tubers, great for making Russian Potatoes, if you plant the larger next year, what yield do you get on average.
I planted some hold overs of that size and as a average got two to three tubers from golf ball size to baseball size.
Plant all were same size, i.e. either gave a few small or a few larger.
Now I have always planted hold over tubers, or bought new ones for planting but in over forty years have never had an odd-ball tuber show up.
I have planted, replanted Victoria now for three years and it produces on a rather boring level of sameness, i.e. same good yield of baseball or larger potatoes.

Germination seems to improve with aging in dry storage, probably because there is a natural inhibitor that breaks down over time. |

Some kinds of the potato can survive winter, indeed. But such potato cannot be tasty.

I have only one season of experience of growing S. jamesii and only from seed, I have never grown them from tubers. billw has stated elsewhere that the Mexican/N. American potato species that show this variable color phenotype do not indicate that it is a fixed genetic phenotype. In other words, if you plant a purple tuber and a white tuber, they will both give you the full mix of colors at harvest. Tuber skin color appears to be influenced by some individual environmental factor specific to each tuber. Possibly age, light, temperature, moisture? It isn't a studied phenomenon. I would expect the tuber size from these to be basically the same grown from tubers as what these are showing grown from seed. S. jamesii doesn't make very large tubers AFAIK |

I harvested them this year and used for cooking. They were absolutely fine and all dishes were great. Not sure what kind of taste are you after but they were as good as potatoes that can be bought in local shops! |

Srdjan, I'm with you. I've had fabulas and superiors winter in the ground and they are regular commercial varieties.
