Free The Seed!

Episode four of the third season of Free the Seed! the Open Source Seed Initiative podcast Do you have questions about OSSI, intellectual property rights, or plant breeding that you would like answered on this show? Please share them with us through our listener survey at http://bit.ly/FreetheSeedsurvey This podcast is for anyone interested in the plants we eat – farmers, gardeners and food curious folks who want to dig deeper into where their food comes from. It’s about how new crop varieties make it into your seed catalogues and onto your tables. In each episode, we hear the story of a variety that has been pledged as open-source from the plant breeder that developed it. In this episode, we'll be talking about carrot breeding in general, and two breeding projects in particular. First, Claire and Irwin will tell us about the Open Source Seed Initiative-pledged carrot breeding populations that they’ve developed at University of Wisconsin-Madison. They’ll explain how the UW-Madison Goldman Lab is able to speed up the seed production process to fit it into one single year using greenhouses and vernalization chambers. Then we’ll hear from Petra about the project to develop ‘Dulcinea’, a new variety offered by Fruition Seeds, which Irwin and Claire have collaborated on. And all three of our guests will weigh in on the basic steps of any carrot breeding project.       Left: Dr. Claire Luby (Photo credit: Matthew Dillon)                  Right: Dr. Irwin Goldman (Photo credit: Matthew Dillon) Petra Page-Mann with freshly-dug 'Dulcinea' roots (Photo credit: Lisa Barker)                    Left: Carrot flower-heads (umbels!)

His plant breeding work focuses on open-pollinated sweet corn, which he has been working on since 2001. On his farm of about 5 acres, Jonathan also breeds kale, broccoli, sugar beets and a few other vegetables. He was a member of the Board of Directors of the Open Source Seed Initiative from 2014-2018. Jonathan and I will be talking about ‘Festivity’, a multi-colored sweet corn. Hi Jonathan – thanks for joining us! Jonathan Spero: Hello, Rachel. Glad to be here. Rachel Hultengren: I’m excited to get to talk about this new sweet corn that you’ve developed. And maybe we can start by having you just describe ‘Festivity’ for us. What does it look like? Jonathan Spero: ‘Festivity’ is multi-colored, in that it has not only white and yellow but blue and red kernels. It has just a blush of color at the milk stage, that is, eating stage. But as the plants mature, they become more darkly colored like what we call an ornamental corn, sometimes. But it’s a sweet corn. Rachel Hultengren: Mmhmm. So take us back to the beginning. How did you get started on this, and what was your goal with it? Jonathan Spero: Well, the original goal was a multi-colored sweet corn. The colors are generally phytonutrients, or this is my premise, and therefore corn with color is more healthy than corn that’s just white. And so this was my initial purpose. I had tasted some multi-colored sweet corn that others have attempted, and thought we could create something that is sweet, open-pollinated, sugary-enhanced and has multiple colors. Rachel Hultengren: Has that been studied before, whether sweet corn that is more colorful has more vitamins that are important to human health? Jonathan Spero: Well, I’m working on a premise. I mean,

It’s about how new crop varieties make it into your seed catalogues and onto your tables. In each episode, we hear the story of a variety that has been pledged as open-source from the plant breeder that developed it. My guest today is David Podoll of Prairie Road Organic Farm. David is a founding member of the Northern Plains Farm Breeding Club, and has worked with his brother and sister-in-law, Dan and Theresa Podoll, on Prairie Road Organic Seed varieties. Prairie Road Organic Seed is located in North Dakota, and focuses on breeding and carrying varieties that thrive in the Northern Plains of the US and under organic conditions. We’ll be talking about ‘Dakota Tears’, an open-pollinated, yellow-skinned, firm-fleshed storage onion, that David has been working on for the past few decades. Rachel Hultengren: Hi David, welcome to Free the Seed! David Podoll: Good morning, Rachel. Rachel Hultengren: So let’s get started by having you describe ‘Dakota Tears’ for us. What makes it a unique onion? David Podoll: Well, unique in the sense that there are a few open-pollinated varieties out there. It’s hard to find a good OP variety in a catalogue today. Other than that, how it’s unique is that it’s unique in the same way that every variety is unique. It has the fingerprints of whoever was the breeder and selector of it, and… Rachel Hultengren: And just to clarify, an open-pollinated variety is in contrast to a hybrid, which is a uniform variety because all of the individuals are genetically identical, whereas an open-pollinated variety is a variety where it’s a population of individuals that are very similar genetically and looking in the field, but are not identical in their genetics. David Podoll: Right. I mean, open-pollinated varieties have a wider genetic base, or they should, and that gives them more ability to adapt. Rachel Hultengren: Mmhmm. Are there aspects of your growing conditions in North Dakota or your management that influence what makes for a good onion on your farm? David Podoll: Well, I don’t know if there’s anything in particular that makes for a good onion. When I started out, I was looking for something that would keep real well, because we wanted to eat as much as we could from our farm and garden. And so I wanted something that would store a long time through the winter in common storage. And um… How I started was I was thinking, “Okay, what in the garden can I save seed from and improve it for our climate here in the northern plains?” Many varieties up to that point had been bred for other climates.

I’m your host, Rachel Hultengren. This podcast is for anyone interested in the plants we eat – farmers, gardeners and food curious folks – who want to dig deeper into where their food comes from. It’s about how new crop varieties make it into your seed catalogues and onto your tables. In each episode, we hear the story of a variety that has been pledged as open-source from the plant breeder that developed it. Rachel Hultengren: Our guest today is Edmund Frost. Edmund is an organic farmer and seed activist based in Louisa, Virginia. He focuses on several aspects of Southeast regional seed work, including seed production, plant breeding, variety trials research, and variety preservation. Edmund runs a small seed company called Common Wealth Seed Growers, and co-manages seed production at Twin Oaks Seed Farm. We’ll be talking today about ‘South Anna Butternut’ – a butternut squash that Edmund has been working on for the past 9 years. Hi Edmund – welcome to Free the Seed! Edmund Frost: Hi Rachel, it’s good to be here. Rachel Hultengren: So I’d like to start by talking about the impetus for this project. The primary trait of interest with ‘South Anna’ is its resistance to downy mildew, a fungus-like disease that affects plants in the squash family. So I’m curious - what was the process of deciding that this was a project you wanted to take on? did you talk with other farmers or gardeners that told you that this was something they needed, or was it personal experience that mainly drove that decision? Edmund Frost: So I started the project in 2011, quite a while ago now, and it was based on experiences of having Cucurbit crops that died from downy mildew. We had cucumbers, winter squash, melons and other crops especially in 2010 and 2009 that did really badly from downy mildew, so it was really on my radar from that. And I guess in 2010 we had a ‘Seminole Pumpkin’ seed crop that did quite well despite the downy mildew pressure. So I noticed that, and I was excited about it, and the next year I thought, ‘Well, I’m growing some butternut, just some ‘Waltham Butternut’ for produce, and why don’t I just plant some ‘Seminole (Pumpkin)’ plants next to it?’ So that’s really how I got started,

Hi everyone! I’m here to let you know that Free the Seed! is returning soon for its third season. This time around, I’ll be talking with plant breeders Edmund Frost, David Podoll, and Jonathan Spero about butternut squash, onions, and sweet corn.

I’m your host, Rachel Hultengren. In this episode, I talk with Craig LeHoullier and Patrina Nuske Small, the co-creators of the Dwarf Tomato Project, the “first all-volunteer world-wide tomato breeding project in documented gardening history”.  We discuss how the project came about, the benefits and challenges of having an all-volunteer team, and the pleasant surprises of plant breeding. Patrina Nuske Small began gardening in her 50's after graduating from Flinders University in South Australia, realizing that it was time to get away from research and spend more time outside in the fresh air. Patrina is currently based in New South Wales. Dr. Craig LeHoullier followed a 25 year career in pharmaceuticals with an ongoing writing career that includes Epic Tomatoes and Growing Vegetables in Straw Bales. He maintained a parallel obsession with gardening, first with heirloom tomatoes, then with amateur breeding. Craig joined Seed Savers Exchange in 1986, and serves as an adviser to the Exchange for tomatoes. Craig is based in Raleigh, North Carolina. Rachel Hultengren: Patrina, Craig, welcome to the show! Patrina Nuske Small: Thanks, Rachel! Craig LeHoullier: Thank you very much, Rachel – it’s an absolute delight to be able to do this today. Rachel Hultengren: Craig, maybe you can start by briefly telling us about the Dwarf Tomato Project. What is the project, and what are its goals? Craig LeHoullier: The project is huge, fascinating, endlessly surprising. To put it all in a sentence, the goal of the Dwarf Tomato breeding project was to offer to the gardening community the largest possible selection of interesting, delicious tomato plants that can be grown by space-challenged gardeners, while at the same time provide a fascinating project for those wishing to become involved in to experience. And in that respect, I think we haven’t only checked all the boxes we set out to check, but we’ve checked boxes that we never thought we were going to check. Rachel Hultengren: Patrina, how did the project get started, and when did it get started? Patrina Nuske Small: In 2005, I was searching the internet for gardening information because I really needed to, like I say, get outside in the fresh air and get away from books.

Bill is the owner of Cultivariable, an experimental nursery on the central coast of Washington state.  He breeds a large number of minor crop species, but focuses on the Andean root and tuber crops mashua, oca, ulluco, yacon, and potato.  In the past ten years, he has released 37 new varieties belonging to nine species and all varieties released since 2013 have been OSSI pledged. ------------------------------------------------------------------------------------------------------------------- Rachel Hultengren: Hi Bill – welcome to the show! Bill Whitson: Hi Rachel, thanks for having me! Rachel Hultengren: Yeah, we’re really excited to get to chat today! So we’ll be talking about your potato breeding, and specifically about a variety you’ve just released, ‘Rozette’, but first maybe we could take a broad view to start, and then focus in. So let’s talk about the natural history of potatoes. Where in the world are potatoes from, and how long have they been cultivated there? Bill Whitson: So we don’t really know how long potatoes have been cultivated, but they originated in the highlands of the central Andes, so think southern Peru and Bolivia. And they were probably first domesticated something like 10,000 years ago. And those landraces and lines of potatoes are now a distinctive group known as ‘Andean potatoes’, or Solanum tuberosum andigenum, which are varieties that are primarily adapted to grow in short-day photoperiods. So what that means is that they don’t produce tubers until the daylength falls to 12 hours or less. And that’s because they evolved near the equator, where the day length changes very little. And this is a common feature you see in tropical plants. That’s kind of an inconvenient feature if you’re growing away from the equator, where the daylength changes a lot. Because, for example, in North America we don’t have a 12 hour day length until fall. So about September 22nd is when we get to that p...

Transcript for S2E2: ‘Lofthouse-Oliverson Landrace Melon’ Rachel Hultengren: Welcome to episode two of the second season of Free the Seed!, the Open Source Seed Initiative podcast that tells the stories of new crop varieties and the plant breeders that develop them. I’m your host, Rachel Hultengren. Every episode we invite a plant breeder to tell us about a crop variety that they’ve pledged to be open-source. My guest today is Joseph Lofthouse. Joseph farms in Northern Utah, where harsh growing conditions can make farming a challenge. We talk about how he has addressed this challenge through his plant breeding work, and Joseph describes ‘landrace breeding’, the process by which he develops genetically-diverse crop varieties that are particularly suited to his farm. Rachel: Hi Joseph – welcome to Free the Seed! Joseph Lofthouse: Hi! Thank you, Rachel and food-curious folks. Rachel: So I’d like to start by painting a picture for listeners of your farm in Utah and the conditions there. Where in Utah are you, and what’s the weather like through the growing season? Joseph: So I am in northern Utah, in Cache Valley, in a village called Paradise. And my growing conditions during the summer are desert conditions with intense sunlight in the daytime and intense radiant cooling at night. Super-low humidity, and I irrigate once a week. Rachel: And how long have you been farming there? Joseph: My family’s been growing in the same farm for 150 years, and I’ve been doing that my whole life as well, except for when I went away to the big city to work for a career, and then I came back home. Rachel: I understand that when you came back home, you found that the conditions that you were growing in, it limited what you were able to grow. I’m curious - what did you try that at first just wasn’t successful? Joseph: So a lot of crops, if I just buy something out of a seed catalogue, about half the varieties I buy that way will just plain old fail. And some things, like cantaloupe or watermelon, might be like 95% failures. Some things like turnips – any turnip that I plant is going to do well here. But the longer season crops, or the warmer weather crops, are hit-or-miss. Rachel: What are the aspects of your growing area that are the hardest for crops to tolerate? Joseph: Well, for warm- weather crops, it’s the radiant cooling at night. And for leafy greens, it’s the low humidity, because we might have 5% humidity in the evenings. And that leads to bitter lettuce and bitter spinach and bitter kale. Rachel: How cold does it get, with that radiant cooling at night? Joseph: We have about, sometimes, a 40 degree temperature change between the highs in the day and the lows at night. And the radiant cooling on the surface of the leaf, probably adds another- or subtracts another 10 degrees from that. Rachel: So that can get pretty chilly for a warm...

Commercially available hybrid varieties are generally highly uniform (individuals in the population will all have the same characteristics) because the individuals are all highly genetically similar. (Hybrid varieties are also often referred to as F1-hybrids.) F1: the first-generation progeny (offspring) of a parental cross. The ‘F’ stands for ‘filial’. F2: the second generation progeny of a parental cross. Produced by saving self-pollinated seed from F1 plants. F3: the third generation progeny of a parental cross. Produced by saving self-pollinated seed from F2 plants. Open-pollinated variety: a population wherein the seed from individuals that have been crossed with other individuals of the same population will produce progeny that are characteristically similar to those parents and the population in general. Off-type: an individual plant whose characteristics do not fit the variety description. Rogue: remove from the field individual plants are diseased, or that either don’t fit with the variety description (if the individual is a member of a well-defined variety) or the project goals (if part of a plant breeding project) in order to keep them from contributing genetic material to the next generation (i.e. so that seeds aren’t saved off them). ------------------------------------------------------------------------------------------------------------------------------------------ Free the Seed! Transcript for S2E1: Gypsy Queens Rachel Hultengren: Welcome to episode one of the second season of Free the Seed!, the Open Source Seed Initiative podcast that tells the stories of new crop varieties and the plant breeders that develop them.

This podcast is for anyone interested in the plants we eat – farmers, gardeners, and food-curious folks – who want to dig deeper into the story of where their food comes from. It’s about how new crop varieties make it into your seed catalogues, and onto your tables. In each episode, we hear the story of a variety that has been pledged as open-source from the plant breeder that developed it. I’m your host, Rachel Hultengren. This episode is a little different from the previous episodes; instead of a moderately uniform, finished variety, we’ll be talking with Don Tipping of Seven Seeds Farm about a diverse spinach population that he has pledged to be open-source. ‘Popeye’, which is available through Don’s seed company, Siskiyou Seeds, has been selected for traits that are important to farmers in southern Oregon, where Don’s farm is located. In addition to the details of the breeding work behind ‘Popeye’, Don shared his thoughts on broader topics relevant to the future agricultural system to which he hopes to contribute. A heads-up about some of the sound quality – when I spoke with Don, he was out in his fields, and you’ll hear the wind blowing by a bit. Our conversation started with Don explaining that his farm isn’t in a prime spinach seed growing region of the US, and how that inspired him to breed spinach. ------------------------------------------------------------------------------------------------------------------------------------------ Don Tipping: I live in SW Oregon, which is known as the ‘banana belt’ of Oregon, because we have hot dry summers and cool moist winters. So a bit of a Mediterranean climate but perhaps a little more extreme in the winters. So typically spinach is grown as a spring and fall crop, just because it doesn’t do well in the heat we have here. But in early May, when spring spinach crops would be growing, it can easily get up into the 90’s which is not ideal spinach growing weather. So we hadn’t produced a whole lot of spinach seed after we learned when we did grow spinach for a few seed companies on commercial contracts that we were just not in the right area to be growing spinach because when it gets hot the plants bolt quickly and it doesn’t have the time to build the stature to produce a good seed head. So ‘Popeye’ really started a bit as a learning experiment and a challenge to that notion of ‘should we only grow seed in the area of the country or the world where it’s most well suited’, which is the industrial model, I would say, that we breed for a particular market and we only grow the crop in the ...

Frank Morton: Hi Rachel, thanks for inviting me. I’m glad you’re doing these podcasts. Rachel Hultengren: Yeah, thanks for being with us today. So maybe you could describe ‘Hyper Red Rumple Waved’ for us? Frank Morton: Okay. Well, it’s an upright leaf lettuce. It’s sort of a romaine shape, but it doesn’t form a dense heart. It’s very dark red, the leaves are puckered and savoyed. The margins of the leaves are wavy, that is the edge of the leaf is not smooth, but it’s sort of ruffled. It has good downy mildew resistance. I’ve gotten a lot of reports about its cold hardiness, and it’s a lettuce that, I don’t know, I think we introduced it about twenty years ago. So I’ve had to sort of refresh my memory about just it a little bit; it’s a lot of lettuces back there. Rachel Hultengren: So it sounds like it’s been a while since it was released, but remembering back, how did you decide to take on this project of developing a new variety? Frank Morton: Well, you sort of have to get back to where I was in terms of my farming life at the time. During that period of time, Karen and I were salad green growers, and we grew salads sort of on subscription for restaurants. It was sort of like a CSA, which is to say a restaurant was signed up for a certain amount of salad each week. And we would ship salad from our farm using UPS trucks and Fed Ex and the USPS and we would ship salad to… well we’re in Oregon here, but we would ship salad to Seattle, to Portland, Boston, Washington DC, Philadelphia, NYC… Rachel Hultengren: That’s quite a reach! Frank Morton: It was quite a reach. We did that for about 18 years or so. And during that period of time,

Maybe we can start pretty broadly – what is the OSSI, for folks who have never heard of it before? Claire Luby: So the Open Source Seed Initiative… it is a project to basically liberate plant varieties from the constraints of IP rights and facilitate sharing and exchange of crop varieties amongst plant breeders and amongst farmers and gardeners. Rachel Hultengren: For those who maybe aren’t familiar with intellectual property as it relates to plants and might be familiar with patents for things like electronics or other physical invented objects, Irwin maybe you could tell us a bit about the brief history of IP as it relates to plants? Irwin Goldman: Sure, yeah, and I think you know I’ve been fortunate to have a front row seat in that. I’ve been involved in plant breeding first as a student and now as a faculty member for the last 35 years or so. And during that time, I’ve watched seeds go from something that you would just freely send to somebody, anybody who requested your germplasm… Rachel Hultengren: When you say ‘germplasm’, what does that word mean? Irwin Goldman:  Yeah, so, germplasm would be the raw material that the breeders are using to develop something. So it’s their seeds,

Carol Deppe: We’ll have fun, I’m sure. Rachel Hultengren: I’m looking forward to it. So today we’re going to be talking about your OSSI-pledged variety ‘Goldini Zucchini’. And maybe we can start by telling me a bit about the variety – what do you highlight in the catalogue description? Carol Deppe: Well, this variety is unusual in a lot of ways. For one, I bred it not just as a really delicious summer squash, but it’s also great as a drying squash, and I’ll talk a little more about what I mean by that. But that means that you can produce a long-storing winter staple from your summer squash patch as well as a summer squash. And for reasons completely non-obvious to me, it also turned out to have spectacular flavor raw. That’s really unusual, because when people say that some squash is good raw, I figure that, you know, it’s edible raw. That’s not the same as being good raw. Basically, the variety got its start when I was reading a book called Buffalo Bird Woman’s Garden. And this was about the agriculture of the Hidatsa Indians in the Upper Midwest. And from this book, I learned that the main way that the Indians ate squash - other than just eating it as summer squash - but their main long storing staple was not the mature fruit, it was dried slices of squash that were harvested at the summer squash stage. That was big news to me, but as I thought about it it made a lot of sense, because the Indians didn’t have good storage space or conditions to store a whole lot of dried squash some place. But they did have good storage conditions for stuff that was completely dry, like dried fruits and vegetables, and dried meat, for example. But at any rate, I thought, ‘Well, this is neat.
