One of the great breakthroughs that allowed the potato to become one of the world’s staple crops was the development of varieties that are day length neutral. True potato seed entry from Rennie’s Annual & Garden Guide for 1920. photo: Toronto Public Library. Once the plants are well established, they are as tough as any other potato plant. OR. Many people claim that it is not possible to get a full yield from seedling potatoes, but I think this is the result of insufficient hardening of the seedlings, mistimed transplant, or difficult growing conditions. in your house) or the potatoes will think it is Springtime and sprout. The ancestors of the Chilean potatoes that became the basis of the modern potato are still grown in the Andes, but they remain almost unknown in the rest of the world. Thank you, Bill. Because seedling potato plants don’t have a tuber to draw on for reserve energy, they tend to be a bit more delicate than tuber grown plants. The number of seeds that you will get from a blender pitcher full of berries is so large that it probably doesn’t matter, but it has been reported by the International Potato Center that a meat grinder provides a superior result, breaking up berries with very little damage to the seeds. International Potato Center (CIP) KWS SAAT SE. I prefer the first method because the conditions necessary for good germination and the conditions necessary for maintaining seedling health aren’t exactly the same. You can also transplant into a seedling bed if you have a greenhouse or live in a suitably mild climate. Feds, Ontario Government Invests $3.5 Million for Online Ag Businesses, Cover Crops Planted After Potatoes Help Soil, Use of seedling tubers that have been raised in a nursery. Typically, you would first dissolve the GA3 in a small amount of rubbing alcohol and then mix that into the water, because GA3 is much more soluble in alcohol than water.). Your email address will not be published. Andigena potatoes are the immediate ancestor of Chilean potatoes. Sowing as soon as frosts end may be important in hot summer climates, where you want the plants to be able to grow in cooler spring weather. 15-07-2012, 11:18 AM. You might also want to think about maturity, dormancy, and disease resistance. Germination time seems to naturally vary among different groups and species, so there is a limit to how much you can improve it. You can perform hand pollinations between varieties. Phureja potatoes are usually small, two to three inches (5 to 7.5 cm) in diameter at the most, but they are colorful, often have unusual shapes and deep eyes, and have excellent flavor. Typical temps then are mid-80s in the day and around 70 at night. On the other hand, if you aren’t looking for easily identifiable traits in the tubers, you then have to wait an extra year before making your first selection. A disadvantage of TPS compared with seed potato tubers is that it is more labour-intensive to grow and it requires a longer growing season. The berries closest to the main stem produce the largest yields of seed (Almekinders 1995). Unfortunately, even if the world does eventually settle on a single system, nobody is going to go back and revise all of the books, research, gene bank identifications, and other material that relies upon the previous classification systems. greenhouse. Checking every inch of your potato fields isn’t an easy task, but precision agriculture company Hummingbird Technologies is trying to make it easier.If you... To cut down on costs and make their operations more efficient Prince Edward Island potato farmers have started using precision agriculture technology to prevent... Agriculture and Agri-Food Canada’s potato breeding program looks a lot different these days, thanks to a major overhaul in the past year. It appears that tuber dormancy and TPS dormancy are linked (Simmonds 1964). Calif. in a hardiness zone of 8 or 9. If potatoes could be grown satisfactorily from true seed, the advantages would be considerable. Many of them have flavor that is superior to commodity potatoes. You should also consider that many modern varieties are male sterile. The sad truth is that several time honored heirloom potato varieties become extinct every year, never to grow again. There are thousands of potato varieties with different colors and forms found in the Andes, but these types are a challenge to grow in North America because they do not form tubers until very late in the growing season. Potatoes that taste just a little bitter may cause no reaction at all in some people, but unpleasant results in others. With tetraploid varieties, you can also isolate varieties that you like and let them self pollinate. Toss a few tubers in the ground and a few weeks later, you should have thriving potato plants. Stenotomum includes what was previously known as S. goniocalyx, commonly known as papa amarilla, a group of small potatoes with yellow skin and flesh, known for their particularly rich flavor. The modern potato, which probably originated in coastal Chile as a result of selection among andigena type potatoes for long day tuberization. Even in the Andes, they comprise a fairly small percentage of varieties; most Andean potatoes are tetraploids. [deck]A look back at this age-old method of raising potatoes.[/deck]. They are grown at higher elevations in the Andes and many have some frost resistance (NRC 1989). If you can wait until the berries drop from the plant naturally, that is the best approach, but pests may make that difficult. Tom and his son also sent us some TPS to cover the pole beans that were confiscated in a seperate order (which I thought was a really nice gesture to cover the loss). In fact, potatoes are usually planted from tubers but also can produce seeds. It is rare that a single application of pollen will fully pollinate a potato berry. Because frosts are rare at these elevations, there can be two or three crops per year. Tetraploid, originating probably from a natural hybridization between a stenotomum potato and a wild relative (Grun 1990). Indeterminacy can be a very good trait for small growers who are not reliant on mechanical harvesting. These include: • Reductions in the cost of growing and transporting seed tubers, a major item in potato production costs. You can find an unlimited number of methods for hardening off, but the main idea is that you will gradually introduce the seedlings to outdoor conditions. They are grown at lower altitudes in the Andes and do not exhibit frost tolerance. This ensures that the seeds receive enough water to imbibe properly and at a temperature where they have the necessary metabolic activity to do so. I live in So. potatoes as with most plants flower in order to produce more seed to further the species. Only a small part of the crop is grown for “fresh use.”  Most people can identify four broad types of potatoes: russet baking potatoes, white and red boiling potatoes, and yellow ‘Yukon Gold’ type potatoes. Another disadvantage for commercial potato producers is that because TPS is the result of sexual reproduction, the crop is not genetically uniform. The Hawkes system is still widely used, particularly in South America, but the Spooner system has been adopted in North America. Frost resistance and dormancy make this group of potatoes particularly interesting for breeding for short season climates. S. stenotomum or S. tuberosum, Stenotomum group. I have grown Zolushka and found basically the same results that were described for Explorer. I like the doubling method: one hour outside the first day, two hours the next, then four, eight, and sixteen hours. Many of the plants were low yielding, but many were also high yielding, so it balanced out. This makes it much easier to determine the genotypes of varieties and to plan crosses more effectively. Compared to a seed, even a small piece of potato has huge reserves of energy and can sprout into a vigorous plant even under less … As with potatoes grown from tubers, it is time to harvest after the tops die down. Once the seedlings are eight weeks old, you need to move fairly quickly to get them transplanted to the field as any with early maturities will begin to form tubers and further growth is limited once tuberization begins. Towill (1983) summarized data gathered at the USDA Potato Introduction Station for both domesticated and wild potatoes. Tubers are round-oblong with deep blue skin and blue flesh. How to Harvest Seed Potatoes. A 24 hour soaking in 50 ppm GA3 can produce more than 90% germination at 60° F (Lam 1968). The optimum time for berries to mature varies from one variety to another and I would generally prefer to not harvest berries that are less than eight weeks old. Keep the surface of the soil moist until you see seedlings beginning to emerge. And inevitably, more will follow. Dry the pollen for 24 hours in a container with silica gel desiccant and it can then be stored at refrigerator temperatures for up to two months without significant reduction in viability. The simplest approach to breeding for disease resistance is to eliminate plants that show any symptoms during the growing season. Taking pictures of each plant as you harvest can be a useful record. The potatoes used in the rest of the world have emerged from a relatively narrow genetic bottleneck as a consequence of breeding them for performance in other climates and with traits suitable for industrial agriculture. Roughly 80% of the seeds produced by self compatible tetraploids with fertile pollen, even in mixed plantings, are self pollinated. Tetraploid potatoes are usually larger, higher yielding, and boring. If you do not have an existing collection of tubers to work with, I recommend starting with true seeds, as it will save you time, have a far lower risk of introducing potato diseases, and should give you much greater genetic diversity to work with. Size and yield are generally smaller than modern potatoes. More intense lights can be kept further from the seedlings. Some are just less domesticated and are holding onto the risk hedging strategy that is present in most seeds of wild plants; spreading germination over a long period ensures that at least some will grow under favorable conditions. Once the basic extraction is done, you have two choices for how to clean the seed: fermentation or detergent. Think about how you want to evaluate them before you start harvesting. phureja or S. tuberosum, Phureja group. To eliminate surface contaminants, such as bacteria and fungi, you can bleach the seed. In the Andes, almost all potatoes are short day tuberizers; they don’t begin to form tubers when there are more than roughly twelve hours of daylight. Then soak for 20 minutes in a 10% solution of trisodium phosphate (TSP). How about the tps? Maybe you would like to experiment with colors and sizes that aren’t commonly available. Because you have not blocked other pollinators from reaching the flower, it is likely that the pollination you perform won’t be the only one. This is a useful trait in the warmer eastern side of the Andes, where they are grown between 7000 and 8500 feet. Bejo seeds has introduced a number of “F1 hybrid” varieties, including  ‘Catalina’ and ‘Zolushka’ in the early 2000s and a new variety called ‘Clancy‘ in 2018. This has the advantage of causing little damage, but would become quite tedious if you are planning on extracting hundreds or thousands of berries. Phureja potatoes are diploids. There are literally thousands of varieties of potatoes. It happened gradually, from a few separate introductions, and most of the early breeding was done by people whom we would now consider amateurs. Potatoes that are exposed to sunlight have increased levels of these compounds, which is why you don’t eat potatoes that have turned green. Modern classification lumps the four categories from the previous section into two cultivar groups under S. tuberosum: Andigenum and Chilotanum. In most cases, seed set is much better with hand pollination than relying on insect pollination. inside these small seed balls are the true potato seed. You might want to take note of things like the length of the stolons that can’t be evaluated later. TPS True Potato Seed. After that, the plants are ready for transplant. To grow potatoes from true potato seed, you need to separate the seeds from the rest of the fruit. Agronomy | Business | Tech | News | Viewpoints | Magazine | INSIDERS | Videos | Buyer’s Guide | SubscribeAbout • Advertise • Contact Us. Although true potato seeds carry much less disease than tubers, some diseases do infect seeds. There is greater demand for tetraploid seed and it typically sells out the same year we produce it. The area can’t be warm (i.e. Tetraploid potatoes are usually self compatible and will set seed that has been pollinated by their own flowers, if they have fertile pollen. One promotional brochure hailed TPS as “one of the most significant breakthroughs for agriculture in the last 50 years,” while another one stated that “conservative estimates by plant breeders indicate that potatoes grown from ‘eyes’ will be obsolete within the next decade. In potato, higher temperatures reduce or completely suppress flowering and pollen production. photo: International Potato Center. If you grow potatoes from true potato seeds, you will discover that potato plants can grow up to five feet tall, that some of them have partly purple foliage, that they have flowers of many different colors, and that the tubers have a range of skin and flesh colors that extends well beyond the white, yellow, and red potatoes most frequently seen in grocery stores. Potato growers need good-quality stock to achieve high-yielding crops and this is more difficult to achieve with seed potatoes than when using true seed. Some commercial seed companies have also conducted breeding trials with TPS. Potato is a genetically diverse crop and the seedlings do not grow true. Tetraploid. By reducing storage temperature to 40° F (5C) or less, they may retain acceptable germination for 50 years or more. They had to learn from experience. Phillipine, India and Bangladesh where as in 34 countries research on TPS was being conducted at experimental station level (Jackson, 1987). This is the group of tetraploid potatoes of Chilean origin. We use 8 bulb, 54 watt T5 fluorescent lamps, hung about 24 inches above the tops of the seedlings. Potato Mutants: Useless Freaks or Precious Gems? Although they are rarely seen in hot or dry climates, potato plants produce both flowers and berries that look like small, green (or occasionally red or purple) tomatoes. If you don’t have time to read all of this right now, you can also get the basics in the Absolute Beginner’s Guide to True Potato Seeds. If you want to be certain about which variety is the pollen parent, then you need controlled pollination. I have been thinking lately how I would like to try true potato seed to grow my potatoes. Early blight can be transmitted on TPS and will often manifest as damping off. Some varieties will flower in warmer, drier conditions, but very few will flower when daytime temperatures rise above 85° F and berries tend to drop early in warm weather. They can be hybridized (with a low success rate, but one still manageable by amateurs) with tetraploid Solanum tuberosum, usually producing tetraploid progeny (Grun 1990). Press the seeds into the surface of your potting soil and cover by about 1/8 of an inch. Being able to successfully identify the diseases is valuable when undertaking such a hobby as like you mention can have devastating effects on neighboring farming efforts. great thanks for these important information .please i want your e.mail address to connected about urgent things on this field. At some point, you will need to evaluate the potatoes that you have harvested and decide which, if any, you will grow again. Under the recommended conditions, expect to seed the first seedlings emerge in 7 to 10 days. The Soviet Union did some work on this, starting in the 1970s and some of the varieties are still available in Europe. There are at least another half a dozen viruses that haven’t been confirmed but probably transmit through TPS at least occasionally. This is the nature of open pollination. One advantage is that it is relatively foolproof if you start with healthy potatoes. I plant seedlings in a bed with a six inch spacing in all directions. S. tuberosum subsp. In most cases, the genetics of potato seeds are not predictable, and may produce undesirable traits. With the recent drought decreasing supply and forcing prices to extraordinary levels in supermarkets, it gives you even more reason to grow your own. That is generally not something that you want, since it will limit the growth of those plants. You can find our TPS catalog section here. 35-40 seeds) Reviews. This is good insofar as it shows the progress of our understanding of the evolutionary relationships between varieties. You will need to pay close attention and make sure that they get enough water and don’t have too much weed competition. The easiest way is to soak each container in water for about an hour and then use a hose to spray the wet soil off of the roots. Even if there is a 100% crop failure or if every tuber spoils in storage the unplanted seeds remain viable and ready to grow. The two main classification systems used in the potato literature of the past thirty years divide the different potato groups into either nine species (Hawkes 1990) or four species with subdivisions (Spooner 2014). There's a great message board that Tom runs too all about what are referred to as True Potato Seeds or TPS. It took some practice, but I routinely get full yields from first year plants. While you can direct sow, the total rate of seedling germination and survival is usually pretty low. If you have grown tomatoes and potatoes before, you have probably noticed the similarities between the two species. The seeds are genetically diverse and growers expect to make selections from the resulting plants to grow the following year, rather than immediately grow a crop for market. So it is only natural that the people in this area used TPS both to produce a crop for consumption as well as to develop better-adapted cultivars. In colder climates with a short growing season, you will probably want to discard all of the short day plants, since the odds of producing tubers are low. Potatoes have two growth habits: determinate and indeterminate, which are largely synonymous with early and late maturities, respectively. There are also additional species recognized for the higher polyploids, but I’m sticking to the basics in this guide. Sorry about that. Although counterintuitive, this has the potential of producing more resistant plants in the long run (Robinson 2007). Increase the spacing by half for dry farming. For example, if you look at our diploid seed mix, we have seeds going back to 2015. This can be very effective, but it isn’t necessarily the best place to start. So, I am not going to describe the characteristics of mass market potatoes or provide instructions for growing from tubers. Read our step-by-step potato growing guide. Otherwise, they are equally easy to detect in the field as long as you start growing them early enough in the year. From nutty-tasting Anya to large-cropping Maris Piper, to McCain varieties and slimmer's choice Vivaldi. The main problem that you will have is that fresh potato seed is dormant and while it is dormant, it will usually germinate only under a narrow range of temperatures – 50 to 68 degrees is what has been reported in research. Unlike tomatoes, which have small flowers and large berries, potato flowers are large and the berries are small. In the USA, the Pan American Seed Company introduced the TPS variety ‘Explorer’ in 1981. Since Florida is a marginal climate for potatoes, I would stick to diverse mixes. Hi guys. Varieties that have little tuber dormancy will often also have little TPS dormancy and vice versa. There are many ways to go about this. Some of the wild ancestors of the potato have much higher concentrations of these compounds even without exposure to sunlight and this trait can show up in potatoes grown from true potato seeds. Growing potatoes from TPS is much like growing tomatoes from seed. CERTIFIED SEED POTATO OTWAY RED 1kg Pack $ 7.90 Sold/Out of Season; 1 2 3 Next → Certified Seed Potatoes. We start TPS outdoors beginning in June. It was mostly F-2 Katahdin. Every potato plant grown from seed is a new variety. Water thoroughly once with room temperature water and do not water again until the soil begins to dry out. This was the group of potatoes originally introduced to Europe, before late blight developed and made it infeasible to continue growing them. Adding activated charcoal to the growing medium may also improve germination. Open pollination is the easier choice. Tetraploid potatoes are further distinguished by having the ability to self-pollinate in some cases. It has been eradicated from the commodity crop, which is grown from certified seed tubers, but it almost certainly persists in hobbyist collections, where many heirloom varieties have been propagated vegetatively for decades. True potato seed (TPS) is a matured ovule of potato resulting from sexual fertilization. aggregatum), Potato: What You Should Know About Potato Fruits, Potato Ploidy and Endosperm Balance Number, Top 10 Beginner Mistakes with True Potato Seeds (TPS), USDA Zones for Andean Root and Tuber Crops, Book Review: Pandora’s Potatoes – The Worst GMOs, Jerusalem Artichoke (Helianthus tuberosus) and Relatives, Yacon (Smallanthus sonchifolius) and Relatives. In North America, the potato is a commodity crop, meaning that it is priced and traded almost completely by weight, destined for processing, with little regard for the characteristics of varieties. This is the group of Andean potatoes and includes everything that was previously included in the Andigena, Stenotomum, and Phureja groups. Many potato cultivars in Andean highlands of South America — the region where potato was first domesticated — flower profusely and produce a lot of fruit.
