TPS

A few King Edward potatoes formed fruiting berries. Now harvested, cleaned, fermented, dried and stored.
Oh the possibilities!

Random Harvest

Here are some of the potato clones which I grew on this year, originally from TPS that I gathered. It wasn't a great year for anything in my garden and I won't blame the weather. The potatoes did all right considering my lack of attention and the absence of rainfall. Many have skins that are quite russety/scaley and tuber size is small.

Two that produced bumper crops and I may continue to clone are the ones below. The first - a red fingerling - I am referring to as Custard right now due to the colour of the flesh and the second with slightly paler yellow flesh I call Humbug. It had a very thick stemmed sprawling habit. But reading the debate here does give me pause. (The film is quite naive but the comments are thought provoking). I worry about carrying disease over to next year's tubers and I think that I'll continue to grow most of my crop from TPS.

... And the Clones

Here is the assortment of tubers that I have saved for growing on this year. All grown from open-pollinated seed saved from earlier TPS. They have been chitting for the past 6 weeks and will probably get buried Easter weekend. It might be time to assign names to them to make labeling a bit simpler. Click on pic for better view.

TPS for 2013

Four weeks after sowing, I've just buried my TPS seedlings up to their necks into the next size up (8 inch) cubby-holes. A great variety of leaf shape, colour and growth habit - woolly purple leaves to green savoy-cabbage-like ones. The first two rows on the left are F2 No.6x?, only dark seeds selected! Then some seed from last year's Minnie's Pig, then (all from Tom @ New World Seed) this year's Minnie's Pig, then ten Fiesta Gold and 10 F3 Skagit Magic. Soon I hope to be taking them out for afternoons in the sun!

Last of the Late Late TPS

Wednesday night's -3° finished off my TPS experiment for this year - an early August sowing. But two of them show great promise I think just for the sheer number of tubers set. And they look big enough to save (see coin) and plant out in the spring!

Late Late TPS

Back in August I decided to test the viability of the seed that I had collected from some of last year's potato fruits. They germinated quickly and I potted a dozen of them on and on and on... Then I moved them into the greenhouse late October to see how long I could keep them going. Now after the second night of hard frost I decided to start to dismantle this experiment. I'm hoping that some of the tubers are big enough to set out in the spring (that is a 1 inch grid) and the little ones I'll taste test tomorrow. There are four more which I will grow on until they show signs of expiring.
The top row are grown from seeds of last year's No.11 plants. Each one is unique. The two outer ones have very white flesh and the one in the centre is quite yellow fleshed. The far right one has lovely markings on the skin. Below are offspring of No.6 plants.
The one on the left has a white ring around a very purple centre, the third one over has yellow flesh and the other two are flecked with magenta/violet marks in white flesh.

Potato Harvest

Both Roseval and King Edward which I grew from bought tubers had to be lifted mid-August due to continuous attack of blight. It would have been a magnificent haul if they could have been left to bulk up for another month as the average tuber count per plant was over 10, so about 400 from just 36 plants. The potatoes that I grew from TPS fared better and I left them in the ground until early October. Below are three that did very well and I will be growing again next year. Of course the Landrace seeds are a mixed bag so very unpredictable but I'm going to save a few of these tubers to grow on as well. And the bottom picture is a selection of some of the ones that I've grown on from saved spuds of previous Tom Wagner trials.

Hairy Glandular Trichomes!

More potato flowers. This to show the more hirsute varieties, particularly 'Boy's Pig'which has little hairs on both sides of the leaves as well (click on picture to enlarge). The hairs or trichomes on potato leaves release phenols and phenol oxidizing enzymes which react to form a sticky substance which hardens to entrap small-bodied insects. I think the first round makes them woozy then in the struggle to escape, they disrupt a second type of trichome which releases polyphenol oxidases. These oxidize the phenols into quinone and it hardens like cement around the feet of the unsuspecting creature. So, more hairs = less aphids! I will save seed from this one particularly furry plant for next year.

Adventures with Potato Seed Continued

I've selected some fruits from the potato plants growing from last year's TPS harvest from which to save seed to grow on next year. Coloured yarn kept with the seed corresponds to bits that are tied around each of the plants so that once dug, I can record the colour and qualities of the mother potatoes. As the bee hive is right next to the experimental potato plot, the results will be anyone's guess. Maybe as quirky as those pictured on Home of the Potato (via ABW)

Further Adventures with Potato Seed

This weekend I exhumed the rest of the spuds from Tom Wagner's TPS. And I think that they hold great promise not least because, although it's been dry this summer, it is now late October and there's still no blight. I am most excited by the tiny round daughters of No.11 as they look very like 'Kuntur warmi' which is Andean for 'Like a Woman with the Colours of a Condor's Neck'. Note, one of the purple offspring of No.6 was a victim of the fork and it's interior is on view.

Adventures with Potato Seed

This year I've been growing some potatoes from true seed obtained from breeder Tom Wagner via Patrick. Although I got started a little late they have now developed into large healthy looking plants. But, what with all this rain and cooler weather around the corner, I'm getting increasingly anxious about disease, pestilence and the like. So as not to have all my potatoes lost in the same basket of blight, I unearthed the above yesterday. The still small but perfectly formed tubers of No.16 (French Fingerling x Magic Molly) and No.21 (John Tom Kaighin x Negro y Azul). Yet to harvest are No.25 (Wild Species x Thumbertime) and No.6 (F2 Pam Wagner) & No.11 (Pirampo x Khuchi Akita) which are just now flowering and setting fruit. I'll leave them for another couple of weeks with fingers crossed. Now, how best to store? I've read 5-10°C and 95% humidity. Is packing in wet sand as you would carrots and beets a good idea? Or perhaps the refrigerator? The plan is to chit and set out next spring for a full crop with taste testing a year from now.
