Carrot Breeding Archives - The Seed Ambassadors Project

“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.

Rodelika carrot tasting, selection and overwinter storage

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.

Early morning on Monday, December 4, we arrived at the doorstep of Christina Henatch, a pivotal player in the German Biodynamic seed breeding scene, Working at the Gut Wolfsdorf Farm outside of hamburg Germany. Christina was gracious enough to host us for several days during a very busy time of year for her. We talked about a great deal — from nematodes and flea beetles to the reality of so-called “organic hybrids” now on the market. We participated a bit in the process of selecting carrots for next year’s seed crop, and helped process some of this year’s carrot seed crop.

We worked a great deal with Juan Richter, Christina’s knowledgable and helpful research assistant, and had what amounted to a four day seminar in the Biodynamic seed world of Germany.

Christina eagerly accepted many of the seeds that we brought, including the broccoli and beans, which are two of her main breeding crops. She was also excited to pass on some of our seed to her colleagues that work with grains, eggplant, salad greens and more. She shared with us some of her favorite carrots, broccoli, and beans, as well as a “naked barley” and some over wintering spinach, and offered us new contacts to explore in her network of Seedspeople.

Christina is a part of the oldest and largest cooperative of Biodynamic breeders in the world, Bingenheimer. Bingenheimer is dedicated to developing and promoting open-pollinated varieties for the professional gardener/farmer that are of the calibar to compete with and surpass hybrid varieties. It is a pivotal time in the evolution of the seed business, especially considering the introduction of “organic hybrids,” and the German Seed Initiative, comprised of dozens of dedicated seed breeders like Christina, is the only organization taking a pro-active stance to ensure that market gardeners will continue to have access to increasingly high-quality open pollinated varieties.
