Our Breeding plots – review of the “Tattie Holidays”

Potato House Breeding Plots

No half-term in Scotland

In Scotland, there was never a half term from school in October. We have always had the “tattie holidays” where the local kids would have the back-breaking task of picking potatoes in October for the local farmers. Farmers’ kids were especially lucky as their holiday could be officially extended if they were still needed to help out. Modern machinery has taken over and large fields can be completely harvested before the children from yester-year would have been been sitting down to their mid-morning “piece”. The school letters are slowly trying to change our terminology, but it will take a long time, especially in rural areas, for the words “half-term” to trip easily off our tongues.

Each year Skea Organics (our parent company), have trial plots where we have to go back to basics and use smaller machinery. The mesmerising video shows the basic lifting machine, hardly recognisable to the modern-day harvester, which runs on the same principle but is 100s of times the size. The nostalgic feeling is also helped by having children working by picking potatoes and bringing their own lunch – we think that our potato-lifting crew may be one of the very few working in fields this year. They really enjoyed it though – well they kept coming back for more which is hopefully the same thing.

Potato Seed Pod

Often we are asked about the tomato-looking thing that can grow on the potato plant after flowering. This is the true potato seed – and is the result of cross-pollination between two potato plants and if grown would be different from both parent plans. However in order to grow these, it would take several years of luck and you may not end up with an edible potato. Potatoes do not need to flower or to have their flower pollinated in order to grow the next generation (unlike most vegetables). The next generation comes from tuber growth and is identical to the parent.Our on-going breeding programme is in conjunction with James Hutton Institute in Dundee where cross-pollination is done in a controlled way to ensure we know what has been crossed with what. The entire process takes years as the new potato will need to go through a variety of tests before being good enough to get it registered on the national database.

This year we had over 800 plots at various stages of selection, which includes control plots and these have to be carefully monitored, documented and of course kept separate. Each potentially could be the next best potato that you will be eating in a few years time! However, many will be discarded along the way. Our main aim is focused to blight resistant and tasty varieties – but the first cut will be how they look – and this can be a gut feeling from when they come out of the ground. We do not know what to expect, especially with the coloured varieties; will the colour be as we imagined. For example, is the result when we crossed a good blight resistant variety with a purple variety what we thought it would be.

The kids were all sent away with some potatoes to try – they will be eating something that no-one else has. Taste-testing is the perk of the job!

We are always after new varieties and within our breeding programme we try to find potatoes not only for the commercial market but also interesting for small gardeners and allotment growers. So far our only registered variety is Mary’s Rose, however we have a wave of new red and blue fleshed varieties in the pipeline as well as more disease-resistant white and cream fleshed varieties.

Our Potato Crew 2020 - Vital for the success of our Breeding Plots

(back row) Byron, Finlay, Rowan, (front row) Adrian, Juliette, Angus, Calum (Morag missing) spent a few days hard at work lifting potatoes around the Auchterhouse area, returning mucky and happy. That’s something for the CV.

    Trying to find seed potato Juliette but not found for over 2 years. Has this variety been discontinued?

      Hi, sorry this was missed. It is best to contact us if you have a direct question. We do not grow or supply this variety. I have checked the UK database and you could find out more here.
