catalog shopping? think like a seed breeder, says joseph tychonievich

joseph tychonievichSURPRISE: You’re already doing some basic seed breeding right in your own backyard, simply by selecting the strongest seedlings that emerge to grow on to transplant size and beyond, or by saving seed at season’s end.

Joseph Tychonievich, author of, “Plant Breeding for the Home Gardener: How to Create Unique Vegetables and Flowers” (affiliate link), says that just a little knowledge of the basics of breeding and genetics might help you shop with new discernment–with the eye of a breeder–from that heap of catalogs on the bedside table.

Joseph, former nursery manager at Arrowhead Alpines, the venerable rare-plant nursery in Michigan, was named one of “six young horticulturists who are helping to shape how America gardens” by “Organic Gardening” magazine, and he recently joined the popular collaborative Garden Professors blog at extension.org and on Facebook. He also blogs at Green Sparrow Gardens, his personal website.

In our conversation on my public-radio show and podcast, Joseph told me how to take best advantage of all the self-sowns that pop up by knowing which to keep and which to thin out; how to apply a smarter eye to saving seed, and more.

Our discussion was the second installment in the second year of my annual wintertime seed series (here’s the whole archive). This year’s series began last episode with Bill Tracy, a longtime professional corn breeder from the University of Wisconsin, and the story of a new organic corn and why it matters.

backyard seed-breeding q&a

Q. I read in the introduction to “Plant Breeding for the Home Gardener,” Joseph, that your breeding career began with some violas at a very young age.  Tell us a little about what got you hooked, and what you focus on today in your own experiments.

A. Yes, the violas were one of the things that got me thinking about plant breeding. I planted my first garden in my early teens, including some violas and pansies. They started self-sowing in the garden, and the bees started hybridizing them, and new color and forms started popping up just among the self-sown seed.

It got me excited, and it was fun to see the different forms that came up, and the way that over time they adapted to my climate and conditions, and started performing better.

I think what really got me hooked was really just the sheer magic of it. To me gardening is always magic: The way seeds turn into plants, I’m still blown away by that. Doing it with plant breeding, there’s the sense of something new—something new to the world—that has come into being in my garden. Watching new flowers come into bloom still really excites me, even today.

[One of Joseph’s self-sown violas, above.]

Q. The word “unique” is a bad word—experts on language point out that most things are not unique, and that it’s overused; improperly used. But with what you just said—with those violas popping up—each one was unique, genetically different from its predecessor or sister-brother-cousin nearby.

A. They’re unique in that sense—they’re something different. And it’s also because they were growing in my garden, so they were uniquely suited to my conditions. That’s because the selection I’d made was not just different, but suited to what I like, and what performs well in my garden.

Q. What lessons about genetics and breeding are most relevant to those of us with our noses buried in the pages of seed catalogs right now?  

A. I think one thing worth thinking about when you read seed catalogs is the people and the location behind the varieties.

Q. The people and the location?

A. Yes. Every variety you’re seeing in the catalogs was bred by a person somewhere in the country or elsewhere.

So, for instance, when I look at the Johnny’s Selected Seeds catalog, they’re in Maine, in a Northern climate similar to mine, so the things they breed do really well for me, versus someone located in a realty different that doesn’t always translate so well.

The context of where that variety might be coming from helps us understand how it might perform for your garden.

Q. So regionality is one thing to look for, one of the clues, because seed adapts, and will reflect where it was bred and grown over many years.

A. Yes. And then I also like to think about the people. Some catalogs are great about mentioning the breeder. To me it’s like when I hear a great song on the radio and want to hear who the artist is.

green zebra tomatoesIf you grew ‘Green Zebra,’ the great tomato that was bred by Tom Wagner—if you loved it you’re probably going to love his other tomatoes. And now he’s breeding potatoes, which I haven’t tried. But I really like his stuff, so I want to try other things by him.

Everybody wants to breed healthy, beautiful, tasty plants—but what that means to each breeder is a little different. When you find something you like, it’s often worth exploring what else they do that might perform well for you.

Q. When you and I spoke recently, you said: “Even if you’re just saving seed you’re really breeding.” A lot of people hear the word breeding and think, I’ve got to cover the flowers with bags after I touch the pollen from one to another, and separate them by a mile, and do all these things.” But some of it is making observations to go with the best of the bunch. I loved Chapter 5 of your book, which has a great title, “Narrowing the Field,” where you say selection is your favorite part of the process.

A. If you’re saving seeds or even just growing seeds, you’re doing selection. The lesson to keep in mind: Life doesn’t stay still. Organisms change and respond to their environment.

If you sow a packet of seeds and 50 percent germinate, you’ve just selected the best 50 percent that were adapted to germinate in the conditions you provided (or the best 50 percent to survive the conditions you stored the seed in).

And that goes on: If you grow out the seedlings and pick out the most vigorous ones, and transplant those, and see which ones survived transplanting. Whether you’re trying to or not, you’re selecting every step along the way.

Q. A friend who manages Turtle Tree biodynamic seed company, Lia Babitch, told me that selection starts when she takes out the seeds from the packet. She looks at the seeds and discards the runts, which at first surprised me.

A. Again, it’s something you’re doing whether you think about it or not. I like to grow extra seedlings to have the chance to choose the healthiest ones. Or when you’re saving seed from your tomatoes, walk down the row and notice if any plants are healthier, or produced more fruit, and save seeds from the very best.

Q. So with something like tomatoes, you might have made observations with which emerged, and which were most robust, and again after some transplants didn’t jump up and grow, and what else?

A. As a breeder, I’m always kind of excited when something comes in and kills most of my plants. [Laughter.]

Q. That’s very nice, Joseph. [Laughter.] Such an optimistic view of gardening!

A. Yes, but when there’s a really terrible winter, or I get late blight on tomatoes (which I haven’t had in years)—it’s really sad, but also interesting to see which plants survived. The plant that doesn’t have blight when all the others do—that’s a goldmine for selecting.

Q. I expect you consider taste when selecting tomatoes.   

A. Taste, yield, beauty—observing every detail of the plant. Some people like a smooth, round tomato; some like the funky-looking ones. Is the plant doing everything I want in terms of performance, aesthetics, flavor.

Q. You talk about looking for who was behind a variety when you read the seed catalogs. Even if I don’t know the breeder names, I look for evidence that someone has been selecting and maintaining and caring for the varieties being sold.

'Butternut' squash after storing till springFor instance at Turtle Tree, they’re been selecting a ‘Butternut’ squash for lastingness–for keeping into the next year [above]. Or at Uprising Seeds, they’ve been working with ‘Astro’ arugula or ‘Chioggia’ beet, or Adaptive Seeds with all their kale genetics, or lettuce breeder Frank Morton at Wild Garden Seed. I perk up when I see evidence in the catalogs of that kind of active engagement with the varieties.

A. And it’s worth saying, especially with heirloom varieties: Just because it has the same name, doesn’t mean it’s necessarily quiet the same plant. Like ‘Brandywine’ tomato lineage may be quite different from one company to another.

Q. I always say, a ‘Brandywine’ isn’t a ‘Brandywine isn’t a ‘Brandywine.’ Try 20 packets from 20 places, and you won’t get 20 of the same thing.

A. And then you get the fun of choosing your favorites among them!

Q. What about managing our inevitable vegetable garden self-sowns: I diligently pull all my tomato self-sowns, to prevent possible disease carryover, but I’m happy to have other self-sowns, especially annual and biennial flowers that make up  what you could call the Accidental Garden.

I’m swear I’m still eating ‘Black Seeded Simpson’ lettuce from a row I sowed eons ago–not the same plants, of course, but descendants. Let’s talk self-sown like lettuce.

A. Lettuce is a great one. I love self-sown plants, because they do most of the work for you. Natural selection will sort through those plants and get you the ones that are best adapted and evolve to grow and perform in your climate.

The next step is to add a little bit of your artificial selection on top of that. For me, I have a lot of different varieties that are all sowing together…

Q. …I bet you do!… [Laughter.]

A. …I always watch and see when they start bolting and go to seed.  [Lettuce going to seed, below.] The first ones that start bolting: I pull those up. I like to le the ones self-sow that waited the longest to go to flower.  Just by looking and saying, “I’m going to pull up the ones that flower first, and let the ones that flower later provide my seed for the next generation,” I’m influencing it.

lettuce going to seedQ. So bolt resistance is something you’re selecting for.

A. Right. When they’re self-sowing, the vigorous ones are going to produce the most seed, so you don’t have to worry so much about the health.

You can look at how they taste and perform, so with tomatoes for instance, you could look at how soon which ones started producing the first ripe fruit—whatever traits you like. Nature will do natural selection to get you the most vigorous plants, and then you push them toward the plants that have the qualities you like.

Q. I’ve been making you talk about lettuce and tomatoes, but you have a particular passion for flowers. What about self-sown flowers?

photo by Joseph TychonievichA. Besides the violas we talked about, columbines are a common one, and Nicotiana often seeds around. Even petunias—old-fashioned petunia varieties do it, too.

The columbines in particular. I always say columbines have no morals. [One of Joseph’s self-sown columbines, above.]

Q. They are sexpots for sure.

A. Whatever you plant, you’re going to have all kinds of crazy hybrids pop up, and again, natural selection will start pushing them toward adaptation to your conditions. You just get to go through and say, “Which colors do I like the best,” and, “Which forms do I like the best,” and you pull out the ones you don’t like.

Q. If I see a self-sown columbine in the garden, and it looks different and I like it, and I save its seed…what will I get next year?

A. Well, who knows? [Laughter.]

Q. Yes, truth in advertising about seed breeding with hybrids.  [Laughter.]

A. Especially with columbines, because they’re pollinated by insects, and insects can fly a long way with that pollen. Unexpected stuff comes up, but it you keep saving the ones you like best, selecting, you’ll gradually move the toward the traits you like best.

Q. It’s a slow process, whether informal backyard plant breeding or the commercial form.

A. But I think the fun part is the variability. I’d be disappointed if my columbines were the same every year—I like something different popping up, the diversity. The process is more fun sometimes than the finished product.

Q. Let’s talk about the role hybrids play in breeding. Especially since worries about genetically engineered seed crops have surfaced, some gardeners mistakenly worry that hybrids (which are not the same as genetically engineered plants) are bad. Even if they’re not confused about what hybrids are, they may skip them because you can’t save their seed, the way you can with open pollinated varieties, including heirlooms. But from a breeder’s perspective, that’s not true, exactly, is it?

A. I love saving seeds from hybrid varieties, because you don’t get the same thing. Instead you get diversity. It’s a lot of fun.

Tomatoes are a good example. Some plants you get a lot of vigor from being a hybrid, like corn, and you can lose vigor when you turn it from a hybrid into an open-pollinated strain.  But tomatoes really don’t lose much vigor. It’s really easy to take a hybrid tomato variety, sow out the seedlings, and then select forms that are similar to the hybrid and create a strain that’s similar to the hybrid but comes true from seed. People call that “dehybridizing” sometimes; I think of it as “customizing.”

Q. Customizing! [Laughter.]

photo by Joseph TychonievichA. For instance, ‘Early Girl’ is a hybrid tomato that I like. It’s dependable, it performs well for me, I always get a good crop from it. The flavor’s decent. If you sow seeds from it, it’s an F1 hybrid but you get some that are bigger, some smaller, the flavor may be a little different, and that’s a great opportunity to me to look through and see what I like best. Do I want it to be a bigger fruit, or a smaller fruit, or what?

It’s an opportunity to maybe get a plant that you like better, and then adapts better to your climate and conditions, than the hybrid you started with.

Q. So Joseph, what catches your eye when catalog shopping? What are you looking for this year, or what’s looking good?

A. This year I am really into big, old-fashioned annuals. Zinnias, and marigolds, and the big, tall cutting ones. I have a soft spot in my heart from them. I’m collecting a bunch of them and this year I want to breed big, tall, blowsy annuals—not like the little, short petunias at the garden center, but big, tall annuals.

  1. tropaeolum says:

    I let a lot of things self sow–like poppies and larkspur and petunias. I believe that by doing that, nature is selecting the best ones suited to the garden. I also collect petunia and marigold seeds. I’ve been saving seeds from the same plants since 2010.

    I saved seed this fall from my favorite chance tomato plant. It came up on the side of the porch and looked and tasted like a cross between Juliet and Sungold. I hope that my seeds are good as well.

  2. Carol says:

    I save a lot of bean seeds, and I like to take cuttings from annuals that winter over that are not supposed to (like Pentas and Scaevola) and plant them out. I have not planted Scaevola in years because I have so much that returns.

  3. Kelly says:

    I’ve had success saving seeds from hot peppers. I’ve also been saving garlic cloves for the past 5 years or so. I love thinning out the least vigorous seedlings from all of my transplants!

  4. Tony says:

    I have always loved self sowing annuals and marvel at their ‘late to the party’ emergence followed by unbelievable flower show. They always make up for lost time and they always, always find just the right spot to ‘sit’. I also love the editing process of thinning them out and removing all the ones that might not be so perfectly sited. Great story and I will certainly get the book.

  5. Sally says:

    I too save seeds especially from ornamental plants. Not so many veggie seeds because I’m afraid of crop failure from vegetable hybrids that don’t work. As far as selection of seedlings, I learned (from somewhere) that for Lupins, the weakest seedlings produce the best color. Is that the case? Thanks. Great podcast!

  6. Sandra Micchia says:

    I have just started to save seeds from my garden, I listened to the pod cast and
    now I am certainly going to save more seeds and as well as use the suggestions
    on selecting the best seeds.

  7. Olivia says:

    I have the curse of the gardener. Sometimes I am overwhelmed by what to save or what plants to thin out. I save the seeds of zinnias, moon flowers and chamomile.

  8. William Pew says:

    My answer: I have consciously saved my own strain of ‘German Extra Hardy’ hardneck garlic for at least 15 years, adapting it to my garden and my preference for biggest heads with biggest cloves.

  9. Michelle says:

    I didn’t realize I was practicing selection but I guess I am with a few varieties of flowers and veggies. I suddenly feel like such an experienced gardener : )

  10. Peggy says:

    I do save some flower/herb seeds but depend on the seeds I buy for the few veggies I have room to grow. Please, I would love to win the book. Thank you.

  11. Amy Sidran says:

    i teach Horticukture at a high school and we have been saving seed from garlic we planted 6 years ago. I now call it our own and the students seed it in fall, harvest in summer, then use it all year long in our culinary program and for braiding! I would love to do more seed saving and breeding with them!!

  12. petra says:

    I have crossed a yellow podded pea with a purple podded pea and hope to be breeding a red podded pea, or at least a partially red podded pea.

  13. Kevin says:

    I have collected and sown many different types of seeds . Last year I had a variegated Cape Primrose that must have self-pollinated itself and produced a seed pod after flowering. I was going to cut the pod off but allowed it to mature to see if it would have any viable seeds. The pod did contain many seeds to my surprise which I sowed to see out of curiosity what they would look like. I now have over a hundred young seedlings with over 50% showing variegation in the first leaves ! Having taken Botany in college I thought variegated plants could only be produced by cuttings or division ; always something new to learn in the gardening world.

  14. Lindy Brown says:

    I start tomatoes and peppers from seed, and save seed from the tomatoes at seasons end to swap with other gardeners. I have helped others ‘grow out’ some tomato crosses, and last year found a cross from my own garden that I have saved seeds from to see what happens next season. Tomatoes are my thing – they are beautiful and delicious! I would love to learn more about breeding plants, especially vegetables. This book would be a treat to read! Thanks!

  15. Sarah says:

    I haven’t ventured far into garden plant breeding yet, but have routinely saved seed from my cilantro plants. I’m looking forward to more seed saving fun in the future.

  16. Terry Rond says:

    I live in a small condo so I can only do container gardening. But I remember my mother collecting seeds from our garden and talking about planting the best performing ones. She also had some beds that she let reseed themselves and I think she enjoyed working with them the most. Ii hope someday to have a house and yard to work with.

  17. Amy says:

    I’ve been letting a kale (originally a red russian) adapt to our garden for a couple years– being a biennial we let it over-winter (yes, it returned in Maine!), then went to seed, then self-sprouted the next year with wonderful results. I’m planning on following through with another round of the same plants after they go to see this summer.

  18. Bobby Ray says:

    I have been collecting suckers from tomato plants which have tomatoes
    that I really like. All was working well till a recent cold snap killed almost
    every one of my tomatoes. I am now building a green house … a bit short
    on money and materials.

  19. Louise says:

    I save tomato seeds, Cleome seeds, Zinnia seeds, poppy seeds. This year I saved fuschia seeds.

    I spread some in new places and leave some perennials outside to naturally reseed.

    It is interesting each fall as I discover more seeds to save. It amazes me that I love discovering seeds to save.

  20. Keisha says:

    I’m currently trying to find the right tomatoes to grow here. Almost everyone has been a failure for the past two years. I have had some volunteers that have done great.

  21. Cris Cantin says:

    I’ve been keeping seed from my Pink Brandywine tomatoes for the past seven years, choosing seed from large fruits that don’t crack (a small miracle with Brandywine!) At this point, I’m getting large, lovely fruits with a 90% no-crack rate. I’ve just started saving seed from Orange Banana tomato, in the hopes of developing a strain that has large fruits that are extra sweet–this will be my third year, so fingers crossed, it’ll be a successful one!

  22. Hillary Lewis says:

    Just this past summer, I put aside tomato and hot pepper seeds. I have never done this before because our was my first time vegetable gardening. But, I’m hoping that the seeds will grow and we will try to save others that we add to the garden this year.
