Biofutur Thanks for posting on the forum...I do have some difficulty understanding your English....such as fecundation...meaning fertilization...which in turn may mean those potato varieties that naturally set berries. As to the potato in full bloom...it looks like a stenotomum...a diploid that needs another diploid variety to pollinize the flowers to get seed/berries. The best I can do to identify the plant is this.... www.amjbot.org/cgi/content/full/89/6/947PAPA AMARILLA PERUANITAS. stenotomum species are obligate outcrossers because they possess a one-locus self-incompatibility system. In other words...they wont set their own berries with their own pollen. |

I cannot get the Peruanita variety here in the states. Getting true seed from it might be of some interest for me.
I did a quick look at varieties of stenotomum that are available as TPS and/or tubers from our national potato collections. I listed the names where I could and eliminated the PI numbers...too much clutter. I have had original tubers of Pirampo and KHUCHI AKITA and TPS of several others...not remembering exactly which at this time without looking up past records.
QOYLLU
MACHU HUANUCHI
CHECCHI CANASTILLA
CANDELARO
No name but from Soplin, Peru
No name but from Paucartambo, Peru
WRF 163 - 197762 x 195213: HYBRID SEED
PITU HUAYACKA
PIRAMPO
No name but from Cochabamba, Bolivia
No name but from Junin, Peru
WRF 2406 - 292110 x 292099: HYBRID SEED
CABRA CHUCHULI
THANTA GUAGUA
SAYLULO
HUADALINA LARGA
KHUCHI AKITA
JANCKO PHINU
RUNTUS PAPA
Because I have complicated crosses and several recrosses of the stens that I have had collected years ago, I should introduce some some newer stens to broaden the genetics again.

Thanks so much Tom.
I understand a bit more the problem now. i'll read the article of the botany society.
No problem for the TPS, I don't expect a lot, but i'll send you some soon. Have you ever tried the CIP of lima. They may send in July or august In Vitro plantlets what you order from their bank.

The last time I made a request direct from CIP finally ended up as a joint request with the USDA Potato Introduction Station. The in vitro must go through quarantine and that can take upwards of a year.

It would seem joeph is suggesting work with what you have that has set seed. If so, I concur. If you want to try cross pollinating onto this variety from others, that is an option also. Effeminating them will be neccesary to ensure self pollination doesn't happen. Whether the fruit take will determine the viability of the pollen from other types you have.
Note this is coming from an amateur who has not done this himself...

 for us in the country where i'm living, just a Phytosanitary Certificate is required for In Vitro material. I just gave up because I went in Peru directly. See, what they replied me. You'r are not lucky. " Thank you for asking material from the gene bank of the International Potato Center, CIP; we work for having a world with less poverty, a healthier human family, well-nourished children and a better environment to reduce poverty and achieve food security on a sustained basis in developing countries through scientific research and related activities on potato, sweet-potato, other root and tuber crops, and on the improved management of natural resources in the Andes and other mountain areas.
The potato material that you are asking for can be distributed next July; we can provide you potato in vitro plants one plantlet in one glass tube 13 mm; with a special culture medium; when you receive it you need to wash the medium and put the plant in a pot and take care; latter you can harvest little seed that you can propagate again at the green house for getting more seed.
For receiving the potato in vitro plants you need to ask an import permit from your country and send it scanned to this e-mail; we will send the tubes by DHL, this have a cost that covers shipment and ask for the National Sanitary Certificate. ". The last time I made a request direct from CIP finally ended up as a joint request with the USDA Potato Introduction Station. The in vitro must go through quarantine and that can take upwards of a year. |

Hy According what Tom explained here upper, maybe the rare pods I'm getting will not be a self pollinization nor a pollinisation with only the "amarilla peruanitas" which were blooming. It would seem joeph is suggesting work with what you have that has set seed. If so, I concur. If you want to try cross pollinating onto this variety from others, that is an option also. Effeminating them will be neccesary to ensure self pollination doesn't happen. Whether the fruit take will determine the viability of the pollen from other types you have. for instance flowers from "ojo azul"  or what I've named "rosada cachan" but in fact I'm not sure of it  |

This morning I harvested my last tubers due to frost. Picture 1You'll see tubers of "peruanita amarilla" standard if I may say that. Picture 2among them there was a variant or impure form, lighter pink color. this was the plant, the only plant which was bearing berries Picture 3These are the berries. They are unmatured, my question is, will they mature more or are they already Ok for seeds ? Picture 4"Rosada Cachan". They were the plants closed to the former. May be it will occureud an pollinisation with it. I don't know. All flowers were unprotected     All tubers and Berries have actual size on the pictures. Thanks in advance for any replies and advices |

I thk you a lot for the link. will be very helpful next season. As I don't think the berries will mature more, I think I'll take off the seeds soon. I got some berries from my other peruvian varieties too, but only one or two for half of them. None of them are as big as these ones. |

Biofutur, La papa peruanita amarilla is beautiful! The TPS berries I harvest this year were green and hard but they mature in the kitchen counter if you wait some time they turn a bit softer, easily squeezable, some turn pale yellow or purplelish red. I used Tom Wagner's technique to clean the gel coating and the remove sprout inhibitors using trisodium phosphate solution and hot water/bleach rinse then dry. I got a tray sowed and started germination within 6 to 10 days. Last year I fermented the TPS seeds and cleaned with hot water/bleach rinse and chilled them for 3 months at 4C they germinated slowly from 10 to 30 days after sowing. Another comment is that washing the potatoes if you want to save them for storage and seed next year is not a good practice. Just brush off the dirt and store in a diffused light cool place with high humidity if you don't have a root cellar. I have my seed stock sampler in the basement in a burlap sack. Here are some in this pic  |

I appreciate your comments, really, they'll help.
In fact after completing harvest I got one to three berries for each variety I grew. but the one I collected the most is the former hereupper. If you want some seeds of it tell me.
I have not tasted it yet. the other true peruanitas are a little mealy, but taste is very good. It must be boiled just enough time.
I'll wait next year for tasting as I got only one kilo from the single plant. I'll keep them safe very cautiously till next spring. It's a good luck we have here in Spain, we may have two seasons for potatoes from march to summer, from august to winter.
thanks again Wmontanez

Merry Christmas, everybody.
Wish I could learn to post pictures.

Really good pics and very interesting, here in the Black hole of Missouri, very few people know of more than two or three varieties, and if you talk about saving the berries for seeds you might as well be on Mars. I'm still way behind on a lot of this, but I'm learning.
