Here are pictures of some of my 2015 TPS, grown from tubers in 2016. 2015 TPS link |

Well, those are very interesting. I've still got pooled seed this year, don't know enough about hand pollination yet.
This is going to be fun, so many possibilities, grin.
Thankyou so much for the pictures.

The varieties in the taste test photos were:
Top row, BLACK IRISH TPS#2015-1, AZULE ROSE TPS#2015-2, AZULE ROSE TPS#2015-3, UNK PURPLE X BIG DOG F1 TPS#2015-2
Middle Row TOLLOCAN TPS#2015-2, SUYTU VILQUINA F2 TPS#2015-?, TETRAMIX TPS #2015-2(Actually a diploid), BIG DOG TPS#2015-9, AZULE ROSE TPS#2015-13 (AKA INTIWANUY)
Bottom Row BEETROOT BLANCA, TETRAPLOID MIX TPS#2015-8 (AKA PURPLE STAR), VICTORIA SA, RED OX TPS #2015-17
Beetroot Blanca was bred by Wendy M from Skagit Beets TPS. Victoria was the other one that was not a TPS tuber.
The results:
These are the net results. With my 3 kids and myself.

The woman came home the other day with some seed potatoes she got at a store. They look nice and healthy and I'm gonna try to plant them today. The varieties are White Superior and Gold Rush. Is anyone familiar with these varieties? I ask cause when I looked them up at the Potato Association of America it says that Goldrush flowers sparsely but sheds abundant pollen and that White Superior makes open pollinated berries. Especially concerning White Superior, does that mean that it might be a stable open pollinated variety? potatoassociation.org/industry/varieties/white-varieties/superior-solanum-tuberosum if so I might get another package of them and grow a little patch in isolation just to see what I get. |

Regarding Superior - setting Open Pollinated berries is not the same as selfed berries. Europotato lists it as pollen sterile. That means all it's berries would be open pollinated (hybrid), with pollen from other potatoes. It would be about the furthest thing from producing TPS that would be stable. This is useful for breeders who want to ensure all the berries are hybrid. Not very useful if you want to get away from male sterility. All its' TPS is likely going to also carry male sterility. "Open Pollinated" in this case does not mean stable, and it does not mean produces seed like itself. It mean, in the breeding sense, "Pollinated only by another potato variety". SuperiorI am not sure about Goldrush. If it has viable pollen, it could be used in crosses or selfed. There is not much data on this one in Europotato. GoldrushBut you were probably seeing this. Potato Assoc. linkThere is no stable TPS line, unless you have something highly inbred. With tetraploids, you might get close with one that self pollinates, but you have no guarantee. There are too many genes in the mix, and with potatoes being outbreeders, you likely are going to get something not very productive ... inbreeding suppression. What would your goal of having a stable line be? Uniformity? |

Anyone here grown Zolushka? That is the one potato from seed I have seen commercially available.

What would your goal of having a stable line be? Uniformity? Thanks for the good info. I don't know that I care that much about perfect uniformity but might like some consistency maybe for color or size. Mostly the potato association info just got me curious. I definitely do not want anything to do with CMS. My interest in potatoes from seed is largely cause I don't have a good storage place for potatoes. By planting time generally all I have is some shriveled up lumps with big sprouts. I figure I got a couple options to compensate, one is to plant in fall which has worked for me and the other is start new from seed each year. My experience with seed is very limited so maybe my notion that you don't get much the first year doesn't have to be the case. I think a good approach might be to go ahead and grow the commercial varieties along side my TPS but only save seed from the TPS plants. That way if one of the commercials is not CMS it's genes can mix in anyway. |

Zolushka is pretty boring, but fairly uniform. Round whites with medium yields mostly. Pollen sterile.

If you live in a potato-friendly climate, you can often get full yields the first year. The less potato friendly your climate, the more likely that you will get poor yields.

Zolushka is pretty boring, but fairly uniform. Round whites with medium yields mostly. Pollen sterile. Interesting - I had assumed that in order to get TPS seedlings with a consistent phenotype, Zolushka had to be a self-fertile, inbred line . . . how would that work if it is pollen sterile? |

One way to get TPS that is uniform is to make many testcrosses and compare the results. Progeny from various crosses will vary both in mean yield and in variance for the mean.
High mean yield is good. Low variance ( uniform) is good if you want to produce lots of uniform seeds, but not good if you want to do selection for further improved yield.
Many pasture grasses and alfalfa varieties are grown from 2 or more clones that have been testcrossed and selected out of 100's of clones that were tested. If a variety is from about 8 or more tested unrelated clones, It can be used ass an open-pollinated variety, breeding true over several generation.
Synthetic varieties of corn are made this way, but using inbreds instead of clones.

Do they grow when you plant them? I remember helping my mother plant lots of "shriveled lumps with big sprouts," and we always got a good crop of potatoes from them. |

Yes, they will grow but in my bin here in the kitchen with wood stove not far away sometimes there is little left except the sprouts and they are often all tangled up with one another. Not at all like the shriveled, sprouted ones you might have at the end of winter in a nice cellar.
