Potatoes primarily come in two different genetic arrangements: tetraploid and diploid. Growing potatoes from TPS is much like growing tomatoes from seed. In some cases, the reason is genetic. Otherwise, they are equally easy to detect in the field as long as you start growing them early enough in the year. This is a commonality of Andean crops, which originated in cool, tropical highlands. As a result, they do not grow true from seed. After that, the plants are ready for transplant. You might also want to think about maturity, dormancy, and disease resistance. After a 4 year absence from my plot I am starting up some TPS again and will this time make an effort to keep a picture diary and label things properly. Controlled pollination requires emasculating the flower: removing the stamens before their pollen matures. How to Harvest Seed Potatoes. This includes most modern potatoes, although modern potatoes are now commonly hybridized with more distant relatives. A 10% solution can be made by adding 24 grams of TSP to a cup of water. It appears that tuber dormancy and TPS dormancy are linked (Simmonds 1964). If you chose not to do an initial transplant, then your seedlings will be crowded together and preparing them for field transplant will take some work. Grow your own potatoes - quality guaranteed! Whichever way you choose, allow the soil to dry out in between watering enough that it begins to shrink away from the walls of the container, but not so much that the seedlings wilt. You can store the pollen that you have collected for later use, which may be important if the varieties that you wish to cross flower at different times. 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. Diploid potatoes are more straightforward for breeding because they have only two sets of chromosomes, meaning only two copies of each gene, called alleles. You can also possibly reduce the odds of transmitting viruses by heating the seeds. Most people don’t do this and still have good results, particularly if they perform two transplants (see below). Growing potatoes from TPS is similar to growing tomatoes from seed, which is a task that many people outsource by buying starts. Growing potatoes from TPS is much like growing tomatoes from seed. " The utilization of true potato seed (TPS) as an alternative method of potato production " Wageningen, The Netherlands May 3, 1994 . If your conditions are a little colder, it can take longer. Almost every potato that you have ever seen at the grocery store comes primarily from progenitors of Chilean origin, a group of potatoes that were introduced to Europe in the 1800s. Then soak for 20 minutes in a 10% solution of trisodium phosphate (TSP). Certified seed will produce 15 –20% higher yields than standard seed. Solynta. These are typically also the earliest berries. Nevertheless, I suspect that it will be a while before we see a uniform TPS variety that can compete with seed tubers. Pre-basic seed (F1 to F3) Vitroplants acclimatization and rooting (F0) Minitubers. A single plant may produce 50-100 berries and single berry contains about 150-200 seeds. Varieties that have little tuber dormancy will often also have little TPS dormancy and vice versa. Once the plants are well established, they are as tough as any other potato plant. You can then save seeds from those plants and you will be on your way to a better adapted potato for your location. This mix will begin to ferment. As a rule, tetraploid potatoes are higher yielding and have larger tubers. This would be a serious problem for potato growing in most areas of the country. The modern day potato has called many different things in the past — here’s a sample.Even though Shakespeare has very eloquently expressed that names... Mutations are naturally occurring phenomena in all living organisms. Although the potato is a common crop, the types that most of us are familiar with are only part of a large range of varieties with different characteristics and uses. Some species showed increases in germination over similar periods. The resulting floating fermentation should be poured off. 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.). Taste is often superior to that of modern potatoes. There aren’t many good sources of information about growing true potato seeds on the web. Disadvantages of dividing seed potatoes are: bacteria & pathogens may be spread between the potatoes on the cutting knife. Pallais (1995) found that seeds stored at high temperature and higher moisture content lost dormancy within four months and germinated at 88%. The potato of commerce is tetraploid, bearing four copies of each chromosome, resulting in a sort of built-in hybrid vigor that typically allows them to grow larger and yield more than diploids. Keep the temperature at about 65° F constant or alternate between 65° F day and 55° F night. Use of high quality seed is very important. Their main distinction from modern and Chilean varieties is that they have short day tuberization. Happy growing folks. You can find this and more information above in the Planting section: “The optimum constant temperature for true potato seed germination is about 60° F (16 C) (Lam 1968, Gallagher 1984, others). With tetraploid varieties, you can also isolate varieties that you like and let them self pollinate. It was because of the genetic diversity in progenies raised from true seed that a century or more ago that gardeners used TPS to raise novel potatoes that they exhibited at county fairs. At some point, you will need to evaluate the potatoes that you have harvested and decide which, if any, you will grow again. There are other reasons as well. Calif. in a hardiness zone of 8 or 9. Towill (1983) summarized data gathered at the USDA Potato Introduction Station for both domesticated and wild potatoes. To eliminate surface contaminants, such as bacteria and fungi, you can bleach the seed. 1. Explorer appears to have mostly disappointed growers, producing small although relatively uniform tubers, but with unpredictable maturities. Keep seedlings under strong light. Good storage qualities. You are more likely to find something that works in your climate that way. For natural pollination, bumble bees appear to be the most active pollinators in the Pacific Northwest, followed by hoverflies and other small, native bees. I live in So. Phillipine, India and Bangladesh where as in 34 countries research on TPS was being conducted at experimental station level (Jackson, 1987). Blue and white are likely to overwhelm other colors in a mixed population. Although you can also transplant them into undivided flats, or containers of any sort, cells avoid the problems of spreading, tangled roots that result if you sow in open flats. Yukon gold was also planted in the same bed. However, when dormancy is broken by exposure to high temperature, seed life is reduced. Once your TPS is clean, there are other treatments to consider. This includes diploid and tetraploid varieties. International Potato Center (CIP) KWS SAAT SE. I will not use that term in the rest of this guide; wherever you see the word “seed,” I am referring exclusively to true potato seeds. Potato seeds can even survive in the field to germinate as volunteers for seven years or more (Lawson 1983), something worth considering if you will be producing a lot of seed. At the end of 20 minutes, rinse the seed clean. You can transplant once or twice. In one famous case, Lenape, a potato bred by the Wise Potato Chip Company turned out to have a level of solanine high enough to occasionally cause nausea and vomiting (Koerth-Baker 2013). Unfortunately, many of them are quite vulnerable to late blight, because the late blight pathogen was not present during their evolution. Thank you, Bill. While the main reason is probably just the considerable extra work involved in raising a crop from seed, uniformity is also a big challenge for commodity potato growers, who have to meet fairly strict criteria to sell a crop a top price. 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. Low dormancy diploids and modern tetraploids are typically very quick to germinate, while more primitive groups and wild species tend to be slower. 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. Hi Charlie. While you can direct sow, the total rate of seedling germination and survival is usually pretty low. The potatoes of commerce in the rest of the world are big and uniform but not nearly as fun as the wide diversity of shapes, colors, and flavors that you can grow from true potato seeds. This is another good reason to start from seeds that have been produced by a population that does not include male sterile varieties. Standard fluorescent tubes must be kept about two to four inches (5 to 10 cm) off the tops of potato seedlings to provide sufficient light (the more bulbs per fixture, the higher they should be). Tetraploid potatoes are usually self compatible and will set seed that has been pollinated by their own flowers, if they have fertile pollen. We get about 30,000 seeds per ounce, so a five gallon bucket full of potato berries will give approximately 150,000 seeds, enough to sow 10 acres if you could manage all the seedlings. The range of potato plants that even most experienced gardeners have seen is pretty small. Under the recommended conditions, you will generally see the first seedlings emerge in 7 to 10 days. phureja or S. tuberosum, Phureja group. These are actual seeds, for a mix of beautiful, multi-colored potatoes, from purples and reds to yellows and whites. Also, these substances break down over time, so fresher TPS often has more irregular germination than old seed. If you want to be certain about which variety is the pollen parent, then you need controlled pollination. [deck]A look back at this age-old method of raising potatoes.[/deck]. 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. This is generally called "true potato seed," or "tps." I presume that mass market TPS varieties will continue to improve though. seed potato material Certified seed lot . There is a small group of diploids, previously classified as S. stenotomum, that have dormancy. Spindle tuber viroid has been present at least in the US in the upper Midwest and Northeast, but is not known to be present in the West or the South. For more information about Andean potatoes, check out our Andean potato guide. Detergent generally produces TPS with less mucilage, which clumps less during drying as a result. And inevitably, more will follow. This prevents self-pollination. Large seed potatoes may be divided up into several pieces, as long as each piece contains at least one eye, to achieve the ideal seed potato size, equivalent to a hen’s egg. ; Transportation of such a huge material is also difficult and costly and can be used as food material. Once you have harvested mature berries, you need to extract the seeds. A wider base of resistance genes can be formed by selecting plants in your first few breeding seasons that are vulnerable to disease, but resilient enough to survive and produce a yield. Once your seedlings are about four inches (10 cm) tall, you should begin hardening them off. That is a big “if”; most tetraploid potatoes of modern origin have pollen sterility problems. 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. Here are the pros and cons of using true seed. If you can wait until the berries drop from the plant naturally, that is the best approach, but pests may make that difficult. 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 most favorable conditions for flowering and berry production are daytime temperatures in the 60s F and nighttime temperatures in the 50s F, accompanied by high humidity. These include: • Reductions in the cost of growing and transporting seed tubers, a major item in potato production costs. In addition to the tubers, the plants are typically smaller and have narrow foliage compared to tetraploids. Some seed companies had it. If the fruits mature, they can develop seeds. True potato seeds can also be started outdoors under natural light. So, you can bet that the USDA is watching sources of TPS that market to US customers and I’m sure that eBay is not all that they watch. The majority of the people I know can be divided into two camps: those who think that potatoes are planted from seeds and those who believe that there is no such thing as a potato seed. They often produce very large vines and, although they form tubers late in the growing season, they can leverage that huge plant to form heavy yields quickly. Most people have probably never thought much about how potatoes are grown. You simply collect pollen from one set of flowers and transfer it to another. Some commercial seed companies have also conducted breeding trials with TPS. If you have made it this far, you might also want to take a look at the top 10 beginner mistakes with true potato seeds. They grow to a certain size, set tubers, and then senesce uniformly. You should transplant into trenches. I bought the seeds through eBay and eBay provided them a list of customers who had purchased that item. Most mutations are harmful in the organisms in which they occur. Since Florida is a marginal climate for potatoes, I would stick to diverse mixes. Farmers Fight Back Against Late Blight With Ag Tech. Think about how you want to evaluate them before you start harvesting. Soak the seeds in 50 C (122° F) water for 25 minutes. You can plant a group of varieties that you like and allow them to open pollinate. If you did an initial transplant, the trench needs to be only about two inches (5 cm) deep, while seedlings that are undergoing their first transplant need trenches about four inches (10 cm) deep. Early blight can be transmitted on TPS and will often manifest as damping off. If you have grown tomatoes and potatoes before, you have probably noticed the similarities between the two species. There is some variability in this trait to select from, so this problem is often overstated, but it does complicate the breeding of diploid varieties. This is not always true, but the details are beyond the scope of this guide. In warmer climates, berries can mature more quickly. While it can be tempting to import true potato seeds from other countries, the US currently allows TPS imports only from Canada, New Zealand, and Chile’s Region 10. Erwinia, Rhizoctonia and other bacterial and fungal diseases can be carried on the exterior of the seed (Pallais 1985, Coyler 1983), a good reason to surface sterilize TPS with bleach. Over time, you can build a collection of your own varieties, unique to your garden. I would like to speak to someone – my phone is 760-749-9022. If we were encountering the crop for the first time today, with the benefits of all our accumulated knowledge, we might choose to adopt diploid potatoes as the foundation of further breeding efforts, but the introduction of the potato to Europe was not planned. A little water stress causes potatoes to form more extensive root systems, which is a big benefit when you transplant to the field (Wagner 2011). There are also many wild potatoes to explore, most of which are rarely available as tubers. Indeterminate potatoes will continue to grow for as long as conditions allow, branching and flowering over a long periods, producing very large plants and, in some cases, very large harvests of tubers. TSP can be purchased at hardware stores. Alternation between 12 hours of 65° F (18 C) and 12 hours of 55° F (13 C) is more effective at germinating dormant seed (Lam 1968), although some wild species germinate poorly when the temperature is not constant (Bamberg 2018). Another would be to wait a year. greenhouse. We sell TPS. You will get a small yield of mini-tubers which can be planted out in the field directly the following year with much less care than is required for seedling plants. By reducing storage temperature to 40° F (5C) or less, they may retain acceptable germination for 50 years or more. 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. Alternation between 12 hours of 65° F (18 C) and 12 hours of 55° F (13 C) is more effective at germinating dormant seed (Lam 1968), although some wild species germinate poorly when the temperature is not constant (Bamberg 2018). At the American Seed Trade Association’s Annual Vegetable and Flower Seed Conference in Orlando, Fla., Charles Miller, commercial director of Solynta, sat down to discuss the benefits of true potato seed, or potatoes grown from seeds instead of tubers. One advantage is that it is relatively foolproof if you start with healthy potatoes. I just found 5 berries on an Adirondack blue plant. Plant the seedlings so that all but the top leaves are buried in the bottom of the trench. So, we normally see only a very small selection of potatoes that were bred from a relatively small number of parents and that were selected to suit the sensibilities of modern agriculture. Stenotomum tubers tend to be long, often with an irregular surface, and colors are primarily white, red, or purple. Despite that, the vast majority of varieties in the world, and almost all of the modern varieties, are tetraploid. Diploid potatoes are self incompatible; they require cross pollination with another variety in order to form seed. I have since collected seed from witchill, edgecot purple and desiree using the information online (Tom W, Ray R, Rebsie etc). At some point after harvest, you will be ready to give your new varieties a taste test. 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. I live in zone 8b (coastal Mississippi). In that case, harvest the berries while they are still firm and allow them to ripen in a protected place. Wondering how to grow potatoes? Although true potato seeds carry much less disease than tubers, some diseases do infect seeds. You will need to pay close attention and make sure that they get enough water and don’t have too much weed competition. Potato color genetics involve a number of genes that interact to produce the different color combinations. It takes a minimum of six weeks for berries to mature (Simmonds 1963). I’d like to plant in the fall as our weather allows for a fall potato crop. production (F1) In vitro multiplication . You can potentially improve germination of true potato seeds in the following ways: For improved germination, you can soak seeds in room temperature water for 24 hours before sowing. In order to maximize hybrid TPS production, you must emasculate flowers and hand pollinate. Seed Potatoes. So, growing potatoes from TPS not only allows you to breed your own varieties, but also opens up the possibility of exploring the much wider range of colors, textures, and flavors that are possible with this crop. They may also take the top six inches of your soil, spray your property with persistent herbicide, shut down any business that you are involved in, and possibly also assesses fines or even bring criminal charges against you. True seed is often considered to be completely disease free, but that isn’t necessarily the case. These efforts have resulted in new TPS cultivars with greater genetic uniformity that are an improvement over previously available TPS and are better suited for certain conditions in some parts of the world. Working with high dormancy diploid potatoes to select varieties that can grow well in North America would probably be a good project for amateur and freelance breeders. Pelleted seeds are easier to handle; this is especially the case for potato where the (uncoated) seeds are small and tend to stick together. Growing potatoes from TPS adds work and complexity to what is normally one of the simpler plants to grow in the garden. Therefore, the primary use of true potato seeds is the creation of new varieties. True Potato Seeds ( TPS) PURPLE EXPLOSION . We probably don’t know all the diseases that can be transmitted through true potato seeds, but there are a few that we do know about: Spindle tuber viroid is transmitted in TPS (Hunter 1969, Singh 1970) and is probably the most damaging virus that infects TPS. Frost resistance and dormancy make this group of potatoes particularly interesting for breeding for short season climates. I have been thinking lately how I would like to try true potato seed to grow my potatoes. True potato seed entry from Rennie’s Annual & Garden Guide for 1920. photo: Toronto Public Library. 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. Flowering is also influenced by day length. However, in climates with a long growing season, short day plants can actually turn out to be good performers. This is my preference. In soil, the seeds may not receive enough water, particularly if they are surface sown. We use 8 bulb, 54 watt T5 fluorescent lamps, hung about 24 inches above the tops of the seedlings. To grow potatoes from true potato seed, you need to separate the seeds from the rest of the fruit. But to answer your question: seed potatoes are stored safely in a cool dark place away from frost. As noted earlier, modern genetic analysis is wiping away all of the historical categories. Although I now keep a lot of tubers for continued breeding, for several years, I grew potatoes only from seed. There are roughly 50 varieties that are commonly grown in North America and they fall mostly into the category of russet baking potatoes, red and yellow boiling potatoes, and fingerlings. The flower might have been pollinated before you get to it and it might be pollinated again after. Breeders of so-called “uniform” tetraploid TPS potatoes are up against the crop’s intrinsic genetic diversity. Potato plants flower and set seed most readily in cool, humid conditions. The TPS had advantage over seed tuber of minimum transmission of viruses and other pothogens. It was off the market before the decade was out. Hi Jim. 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. In recent decades, the seed industry has made progress in pelleting seeds. There is no sense in rehashing topics that have been covered many times already, in depth, by people who are far more authoritative than I will ever be. You can then use a small brush to paint the pollen onto the flowers that you want to pollinate, or if you have collected a lot of pollen, simply dip the flowers into the container. Why don’t farmers grow entire crops from seed? S. phureja subsp. This was the group of potatoes originally introduced to Europe, before late blight developed and made it infeasible to continue growing them. The area can’t be warm (i.e. Some varieties will set seed even in hot, dry conditions, but the widest range of varieties will flower and fruit in maritime climates. Do you have problems with potato diseases, but hate buying certified tubers? For the most part, these diseases aren’t common and don’t spread easily through TPS, but great care should be exercised whenever introducing varieties of unknown provenance. For small quantities, you can merely cut berries in half and squeeze out the seeds. Ok, so to my question. Potato tubers for planting are often referred to as “seed tubers,” which complicates discussion. Every potato plant grown from seed is a new variety. Potatoes, just like other vegetables, flower in the summer. In favorable weather conditions, flowers appear two to three months after tubers or seedlings are planted out. Varieties can only be maintained by replanting the tubers. When light drops below 14 hours, and particularly below 12 hours, you will start to see plants that tuberize early due to the short day photoperiod. Certain pesticides may inhibit flowering in potato. With the recent drought decreasing supply and forcing prices to extraordinary levels in supermarkets, it gives you even more reason to grow your own. Quantity. Production of seedling tubers from true potato seed (TPS) in protected area Cioloca Mihaela1*, Baciu Anca2, Nistor Andreea1, Popa Monica1 ... major disadvantages of potato hybrid progenies. I have emailed you. At that point, you have two choices: you can prick out the seedlings and transfer them to another container or you can continue to grow them in the original containers. If I may ask a related question …… are the seeds you sell fresh or are they aged enough for their dormancy to have broken down? It is, however, rather confusing for the amateur potato breeder, because the potato literature is filled with references to outdated systems. Other Advantages of True Potato Seeds One of the best advantages of planting true potato seeds is that I do not have to overwinter potato tubers. Don’t forget that lights will increase the temperature. In the 1980s, research efforts by the International Potato Center (CIP) in Lima, Peru resulted in a flurry of activity among some North American seed companies that targeted home gardeners to either raise their potatoes from true seed directly, or to purchase young plants in plastic containers from garden centres. In Canada and other developed countries, the disadvantages of growing TPS on a commercial scale are seen by many to outweigh the advantages, which is why almost all commercial potato fields in North America continue to be planted with seed tubers. S. stenotomum or S. tuberosum, Stenotomum group. Tetraploid. Alternatively, you can hill on top of flat ground, but make sure that your hilling spreads in at least a 12 inch (30 cm) radius around the plant. 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. Both surface sterilization and heat treatment are usually recommended to ensure that seed is clean. • TPS may be more easily stored than tubers.
