Bringing Biodiversity Back

Month: January 2007 (page 1 of 3)


“One of the central hubs of German biodynamic plant breeding community”. We were told this by many people through our travels and we decided that we had to visit Dottenfelder-hof (translated version). After a nice hike in the morning from the train station we arrived invigorated to meet with our host Martin Kern, a very personable character with many years of plant breeding experience. Martin showed us all around the Hof, with brief stops at many of the farm’s constituent areas. . In German biodynamic tradition the site is the collection of many integrated and collaborative facets. Some examples of these endeavors are the plant breeding programs, dairy cow and chicken production, cheese and bread making, anthroposophical educational programs, and a biodynamic storefront. Many of the people who worked there lived there too and with all that was going on, it was a bustling scene (about 100 people living and working there).  I could compare it to intentional communities in the US but that would be misleading. The place seemed more like a well organized, fairly self-sustaining village. Lots of people making a living centered around an agricultural and educational foundation.

Some of their achievements in the area of plant breeding:

Carrots – Dietrich Bauer has spent over 20 years breeding vegetables. What he is most famous for is his carrot variety ‘Rodelika’, available in the US through Turtle Tree Seeds. This carrot is famous for its flavor, especially when juiced.  “Rodelika” juice is available in the juice section of many stores that carry biodynamic products, right next to the standard “carrot” juice.  More marketing with variety names is something that could help expose people to the diversity of crops and help preserve those crops actively within society, like an old story or play. While at Dottenfelder-hof we helped select Rodelika lines for flavor and yield. Getting both flavor and yield simultaneously is one of the more difficult aspects of plant breeding. By the way, the carrot juice is excellent.

Ulla Grall’s Bio-Saatgut

From Switzerland we traveled back north up to Germany for a visit with Ulla Grall of Bio-Saatgut. The name of her company says it all: “Organic Seeds”. Ulla offers through her catalog seeds that she produces herself and those grown by several small contract growers, as well as seeds from Sativa Rheinau and a French seed company called Ferme de Sainte Marthe. Ulla told us she wants to grow more of her own seed herself, but also takes pride in the fact that she offers seeds from two other countries. Because of the EU seed laws it is difficult for many people to order seeds from other countries, or they simply don’t think of it as an option. Through her seed company, Ulla offers many varieties that would otherwise be unavailable to German gardeners.

Ulla became involved in seeds initially as a translator and marketer for Ferme de Sainte Marthe in Germany more than a decade ago when the company was trying to expand into the German market. After Ferme abandoned this project, Ulla took on selling some of their varieties personally. What began as a small mail order resale company has since blossomed into one of the only independent organically certified seed companies in Germany.

Pro Specie Rara – Swiss Seed Saving Organization

Pro Specie Rara (PSR) is Switzerland’s seed savers exchange. Unlike the American Seed Savers Exchange, PSR focuses solely on Swiss heirloom varieties: in order for a seed to be accepted into the PSR collection, it should have been grown in Switzerland for at least thirty years. For this reason, there are PSR listed Swiss heirloom Chioggia beets and many types of “French beans.” Traditional Swiss agriculture (and gardening) was heavily influenced by its neighboring countries (Germany, Austria, Italy, and France), as was the language, so the Pro Specie Rara inventory is quite varied. In addition to the vegetable varieties, PSR also promotes the stewardship of traditional animals and fruits. To date, 25 breeds of rare animals and dozens of fruits are promoted through the organization.

Pro Specie Rara is 25 years old in 2007, and at the peak of their acquisitions they obtained hundreds of heirloom varieties each year — seven or eight years ago they acquired 100 – 200 new sorts per year. The past few years, though, fewer and fewer varieties have been submitted, and in 2006 they only received 20 new accessions. Marianna Serena, who manages the seed collection, said she feels good about the quantity of seeds they have, adding that the organization is about at the limit of what they can care for. Pro Specie Rara doesn’t have its own gardens like some other Seed Savers organizations — they are more of a networking and marketing hub for old varieties.

Sativa Rheinau part two: Breeding Projects and More

The folks at Sativa do a lot of work with maintaining and reinvigorating old varieties for PSR. (Pro Specie Rara, the Swiss seed saver’s organization, see next posting). Most of this work focuses on brassicas, which often suffer from inbreeding depressions, leading to sickly plants and poor yields. By the time inbreeding depression is recognized it is often too late: one cannot simply grow out a large population of the line and save seeds, as the genetics have been bottlenecked by previous small populations (e.g. a home gardener saving seed from too few plants). The only glimmer of hope is to locate other lines of the same variety and cross the lines together — and this is exactly what Friedemann, the vegetable breeder at Sativa, is doing.

The prime example of this tragic condition is found in the red Brussels sprout variety known as Rubine, still carried by many seed companies throughout Europe and the United States. Rubine has declined over the past several decades and now often fails to produce anything resembling Brussels sprouts. Friedemann recently acquired Rubine from six different sources throughout Europe, with plans to let them all flower together in the hopes that the different lines will bring enough genetics together to reinvigorate the variety — hopefully to the point of producing healthy plants that will produce large sprouts. If this cannot be achieved, he said he will begin work to develop a new red Brussels sprout variety.

Sativa is also involved in Biodynamic breeding projects of a completely different sort than Ute Kirchgasse and Christina Henatsch (see previous posts). Friedemann came to biodynamic vegetable breeding from quite the opposite direction of Christina and Ute. His training and experience is not Anthroposophical, but rather he worked as a vegetable breeder at Hild, a conventional seed company.

It follows, then, that Friedermann has a different approach. In contrast to most of the Biodynamic community, he doesn’t see any problem with the wise use of F1 hybrids for breeding (unless these hybrids are geneticly engineered CMS hybrids). Friedemann doesn’t create hybrid varieties for sale or distribution, but acquires them from other seed companies and then uses these varieties as breeding material. He believes the organic/biodynamic community should utilize the genetic resources and hard work of the conventional community, just as the large seed compaines use the resources of the open-pollinated community in the creation of their hybrids.

Sativa Rheinau part one: Swiss Biodynamic Seed Company

From Gerhard and Susanne’s we traveled by train south to Sativa Rheinau, a biodynamic seed company in Switzerland near the border town of Schaffhausen, home to the largest waterfall in Europe. Set in a seventeenth century monastery on an island in the Rheine, Sativa is blessed with being one of the most beautiful places we have happened across in our travels. The seed company at Sativa is part of a larger Biodynamic farm project that integrates 25 handicapped people into the work with animals (dairy and meat), fruits, vineyard, grains, and seed growing and processing tasks.

Sativa’s main vegetable seed customers are home gardeners, and they work closely with Pro Specie Rara (PSR) to distribute heirloom Swiss varieties. (More about PSR, the Swiss seed savers group, in a later posting). Sativa’s main work with farmers is in their work with seed potatoes and grains, and they sell large quantities of rye, spelt, and wheat to farmers there. Because Switzerland is not part of the EU, they do not have the restrictions of most other countries in regards to the Common Catalog. But this does not mean that they do not have to deal with limitations; as is the case in the US, high quality open-pollinated varieties for market gardeners are either nonexistent or are hard to come by.

Gerhard Bohl, Plant Collectioner

After another pre-dawn start, we left the company of the kind folks at Bingenheimer and headed south towards Nuremberg and beyond. Our next stop: Gerhard Bohl’s home and gardens in the hamlet of Rednitzenbach. Gerhard and his wife Susanne are the brains, braun, and brilliance behind Das Sortenbuch (= the variety handbook), a mail-order catalog collection of more than 2,000 tomatoes, 380 peppers, 700 beans, and hundreds of other rare and unusual vegetables (written in German).

Gerhard trades straight across with gardeners and fellow “collectioners” to the tune of some 20,000 seed packs per year. He distributes another 30,000 seed packs per year through other venues, mostly through his mail-order catalog with gardeners in other parts of Germany. Gardeners must write him by post and send five Euro for a copy of the Sortenbuch. If they decide that they want something from the buch, (how can they not?), they write again and send one Euro for every seed pack that they order, or if they are seed savers they can send in seeds from something they have grown in lieu of the cash. To encourage his customers to participate in the exchange and the stewardship of varieties, the Sortenbuch has several pages in the beginning that instruct people how to save seeds. This information is an important part of Gerhard’s work, as German-language editions of seed saving books are not common.
