Papas: Late blight and frost resistence + notes

[trixtrax]

Hi there! I have been lurking for a while meaning to post, thought I'd share some results from this years season.

During the 2012 growing season, I grew about 150 vars of potatoes, collected over the years from personal trades, wingnut, Tom, Will Bonsall, and others on SSE. They are a mixture of heirlooms from S. America, US and Europe, Tom Wagner creations, USDA GRIN accessions, breeder lines, commercial mainstays, and Pacific NW heirlooms and other taters of interest.

I wanted to trial a lot of diversity, but at the same time I also wanted to identify some of the top performers in my conditions. Some things I set out to observe and record were tuber attributes like shape, skin color, flesh color, stolon length and tuber set depth, history and species information, disease resistances, frost resistance, productivity, aesthetically pleasing tubers, and of course tastiness/culinary usages. I suspect I will cull about 15-20% of the weakest performing varieties in order to focus on the best in future breeding programs. After cleaning up my spreadsheet a bit more, I will give it to Curzio to publish on his site, Kenosha Potato Project and/or also place it here somehow. I still have to "finish" it a bit more, though filling in all the fields such as culinary usages will take several years... Also, happy to trade taters for new stuff with anyone.

This year I almost exclusively grew potatoes as pull starts in 4in pots, transplanting once they established directly into the ground with the exception of some purchased seed potatoes. They were planted in the field in a 1 ft deep trench at 2 ft centers for typical taters and 3 ft centers for plants that set tubers on long stolons like Guincho negra, Herm 18, Poor Dog I, Poor Dog II, Black Irish, Aggie White, some Skagit Diploids and a number of other diploid vars. Rows were spaced at 3 feet. I have to credit Wingnut for teaching me this method. He's been experimenting with this method and having success, so I had a go, too. Can't recommend it enough, as it vastly improves vigour in almost all potato varieties, we suspect due mostly to disease removal. I'll talk to Wingnut about working on documenting how to do pull starts successfully and post it here when I get the chance.

One gotcha I've heard about and experienced first-hand this year, was that if a pull start is let to grow in a pot too long, many varieties will set fixed-size tubers after certain point no matter what, even if emergency transplanted into the ground. S. tuberosum seem to be more "determinate" and thus more susceptible to being root-bound in 4in pots and will often fixate the size of the tubers for the season if a pull start is left in a pot for more than about 2 weeks, while the diploids seem more "indeterminate" and able to be advantageous and grow out of a root bound zone when a 4in pot is transplanted into the ground. This is a trend and does not always hold true for all varieties. I suspect this effect is due to the fungi and bacterium that associate with the roots communicating the boundaries of the grow space to the plant.

The Pacific NW, being a cold, damp, wet climate, we have our share of potato diseases and pests, that includes black leg, pocket rot, scab, purple mop-top, early and late blight strains, Rhizoctonia, leaf hoppers, flea beetles, wire worm, sometimes even potato cyst nematode, etc etc. It's a wonder the plants can grow and is a testament to how hardy this organism is. Planting in a spot is a bit like roulette, what diseases will I incur the wrath of there? One constant is late blight, so I was keen to take notes about which varieties performed the best against our local late blight strains. I know that since I planted pull starts from April to July, having received new varieties over a period of time, some inevitably missed some of the disease/pest waves. Also, a subset of the tubers that I knew were contaminated with potato cyst nematodes which were quarantined into 4in pots by themselves, so those couldn't really be tested either.

On the topic of potato cyst nematodes (PCN), I am currently growing these under lights and will be treating with Nicotine sulfate to see if that wipes them out. Thankfully this nematode species is easily visible to the eye. Again, simply doing the pull start method has visibly impacted the population level on these tubers.

So, which varieties performed best against the local late blight strains? The following varieties were either unphased as a planted block by late blighted plants next to them, or were mostly unphased, or regenerated well after being blighted: Toro Azul, Kameraz, Red Eye 86F-302-8, Fripapa, and DG-D8-330 Polish. Like I said this list will probably grow when I can control the variables better this year.

As for frost resistance, the Skagit Diploid series as a group had good frost resistance with a few varieties having exceptional frost hardiness as compared to the others. "Maori Purple" a primitive looking purple (which looks very similar to Guincho negra and Herm 18) from New Zealand was by far the best being frosted for over a week and still standing with plenty of regeneration. I am not sure what this varieties real name is, all I know is it is not the Urenika clone. Others included: Perricholi, Santa Ana, and Santa Catalina. Again, I'm sure results were effected by the long stretch of planting time and also the fact that some varieties are just so early in the season that they don't have a chance to be tested by frost... unless deliberately planted late.

As I was looking up information from USDA GRIN, I came across a USDA Frost tolerance Experiment by Bamberg in 1992. They trialled 2624 accessions for frost and recorded results. I want to request some of these accessions to add into the mix, but first I needed to sift out the gold. So I downloaded this data and using grep eliminated any species that probably were genetic dead-ends, too far out of the petota complex, or didn't produce tubers at all. Then I eliminated any that were not very frost resistant or frost resistant and in the highest percentile where noted. Unfortunately, not all the tested accessions were scored, so this limits its usefulness somewhat, but as I understand many were included because they had previously been noted to carry some frost resistance. Sorry, the list is still a bit messy, but it took some work using sed to clean it up to the point where it is at now. Some misc. species are still in there that I haven't yet looked up or didn't have enough information to warrant removal. If you have some info about a particular species (TOM!!?), please chime in so that I can star it on this list or remove it altogether so that this list stays current.

Thanks, Chris, for chiming in ...yes you have lurked for the last three years. And to think you are one of the few people who have helped me harvest potatoes from my plots over the last few years.

Your post is a bit too large for most of us to digest in one sitting.
One of the best lines out of Bolivia for frost resistance is CIP 575045 and is a great yielding potato variety too. My crosses are also tolerant to frost and freeze resistant in the ground too....just recently dug some that are super...none froze like other varieties in the ground. Here is the information....

I have tubers of each of the following lines plus TPS from both parents of the Idaho lines and in many combinations. I am not lacking frost resistance.

Solanum sanctae-rosae or now call boiviense dominates your frost tolerance list. Just try to find som good tubers among that group….it will be tough.
Too long of a list to look at in one viewing…a work in progress for many.

BTW…I have good results from at least one of the list…second from the bottom
I sell TPS of the following…


Criolla Rosada (phureja) - Potatoes

www.tomwagnerseeds.com/index.php/criolla-rosada.html
Throws lots of red skin, light yellow fleshed tubers. Many primitive shapes.

[trixtrax]

Hi Tom,

The CIP 575045 sounds very interesting, do you still have seeds of this variety?

[trixtrax]

I just ordered the various Solanum tuberosum subsp. andigenum from above.

[trixtrax]

The above list was paired down from a really long list using some command line software to arrive at a list of at least crossable tubers with a few stragglers that probably couldn't cross.

[Tom Wagner]

PI 595409 CIP 575045 Frost tolerance. Late Blight resistance.

I know I have seed somewhere on the one above. Good freeze resistance in the soil all winter...produces some great progenies. I probably left most of the tubers go to get rid of virus infection.

"Maori Purple" a primitive looking purple (which looks very similar to Guincho negra and Herm 18) from New Zealand was by far the best being frosted for over a week and still standing with plenty of regeneration. I am not sure what this varieties real name is, all I know is it is not the Urenika clone.

If you got the "Maori Purple" from Wingnut then the source was most likely me, I sent him a 1st year tuber apical ends from one of the segregating plants from TPS grown of 'Mystery TPS' that I've got from Richard Watson of New Zealand. The potato is elongated but the flesh is purple/white, the plant is very disease resistant. The mother of that TPS, all I know is that is called Mystery and it was bred from Urenika.

 I've got great results in all of the TPS segregation from it. I grew it as 1st year clone and was surprised at the results: white clone is extremely productive, the blue clones are excellent flavor. The segregation I got from 'Mystery TPS' will remain unnamed until this next year after I get Richard's blessing to name 2 of the clones I selected to continue. 


1.Round, solid purple flesh (good flavor)
2.Oblong, white (boring flavor, extremely productive)
3.Elongated, purple/white flesh (the best flavor, productive)
4. Elongated some rounds, red/white flesh (good flavor)



If that "Maori Purple" you got it from Wingnut then it originated from me then I am most happy seeing my babies in good hands!!

[trixtrax]

Wendy,

I think you are correct about the origin of Maori Purple. That name was just a placard name I gave the variety.

[wmontanez]

Trixtrax:
Glad you got them there and would love to see a picture of them ....

[richard]

Wendy you have my blessing to name them what ever you want as i'm not currently growing Mystery,its being looked after by a friend who also is growing your (4. Elongated some rounds, red/white flesh (good flavor)) in the photo,what ever you name it he will use as well as he has not put a name to it,we never carried on with(2.Oblong, white (boring flavor, extremely productive)because as you pointed out there was nothing nice about it.The ( 1.Round, solid purple flesh (good flavor)is so much like Mystery,how did the size improve with subsequent grow outs Wendy?.
As for ( 3.Elongated, purple/white flesh (the best flavor, productive),i dont think its thrown back to the Urenika as much as the original,the original Urenika is has more solid purple colour than what i can see in the photo.

The reason why ive given my collection away is that i want to concentrate on working with Moie moie TPS,i have four different strains,one of my original line and three from cesarz, plus two others that are from the first time in 25 years that Moie moie grew TPS.All these have been mixed up within on large bed and thanks to a cooler than normal summer so far i'm getting a fair amount of berry set on all of them especially on the TPS moie moie tubers.

[wmontanez]

Thanks Richard!

As far as #1 Richard, the one clone Mystery from you very similar yes. As far as production, I got more from your clone than my TPS tuber.

As for #3 it does have the Urenika shape but mine where too much white inside, but the flavor is excellent and that is the one TrixTrax grew and he has said how was frost resistance.

I accept your blessing for naming and would like to use some maori words in the name for those I will continue to grow as they are descendants of Urenika.

The red&white (#4 elongated) what about "Mystery Wheroroa" (Long Red)? and ...
the solid purple (#1 round) what about "Mystery Waiporoporo" sounds cool eh?

The white even thou is boring I still have it around if I grow it then I will call it Maori White.

I might still have the #3 clone somewhere not sure.. Since our friend Trixtrax name his already as Maori Purple I would not change it.

I am interested in TPS from the Moie-Moie as I lost the clone (so sad!!!)

[richard]

Mystery Wharoroa sounds cool by be me,i'll keep an eye out for a Urenika clone to send you,its a long season cropper that if you can keep it going that long produces very good crops .

I'll be too happy to send you some of the TPS Moie moie and share some round the other northern folk

[trixtrax]

I hope to cross Maori Purple to other dark purples this year.

[wmontanez]

Trixtrax I left one tuber of the original Mystery clone selected by Richard unplanted in the unheated basement for 18mo. still alive. Talk about good keepers. So I hope the TPS offspring is the same. So far the red and blue selections I made just started to sprout but Richards Mystery clone is STILL in eating conditions.

So yes. I am getting my hands on Moie-Moie TPS so any offspring from TPS I will post here. It would be great a real farmer get these genetic material.

Good luck with crosses

[jondear]

Still in eating condition after 18 months? I'd settle for 8 months... in or out of the ground. I've had some missed tubers regrow come spring so maybe I'll try a planted row this fall.

Wendy are you planning to grow out that tuber this year?
