The Challenge


Today we are facing an unprecedented challenge to our very survival as the climate destabilizes. Farmers everywhere are scrambling to find crops that perform well under stressful conditions. At the same time, we have lost 90% of the crop varieties that were available just 80 years ago, as corporations have moved to commodify and monopolize all aspects of our food system.


To counter this dilemma, Seed rEvolution Now is working with skilled, certified organic seed growers and seed specialists to promote and provide open-pollinated (OP) top quality certified organic seed that farmers can save, select, and regrow if they so desire. This is our heritage and our birthright.

Meeting the needs of organic seed consumers


Organic market farmers face continuous and growing challenges to meet the desires of their customers. Seed Revolution Now offers help, matching seed customers with producers who can develop OP varieties that address market demands.


Traditional OP Breeding

We have been told that GMO technology is the only way we can possibly feed our burgeoning population. This is not true. Traditional breeding is fully capable of meeting our needs. OP breeding allows every generation of plants to respond to a changing environment, with each new selection leading to further adaptations. Key features of this dynamic approach include:
  • Developing “workhorse” varieties for a wide range of environments.
  • Developing varieties for specific climatic and soil conditions.
  • Selecting for durable, multi-gene disease and/or pest resistance.
  • Breeding for plant vigor and reliably high yields.
  • Selecting for distinctive consumer qualities such as outstanding flavor, unique color, and elevated nutritional content.
  • Invites the participation of seed customers in the improvement of varieties for their specific needs.
  • Allows farmers to save and select seed, if they so choose, for their own seed sovereignty.


 Seed Bred For Organic Conditions


All of the varieties offered by Seed Revolution Now are open-pollinated, public domain, and organically grown by skilled certified organic seed farmers. They are either tried and true heritage varieties or new improved selections with characteristics that are especially valuable for organic market gardeners. At times we may offer seeds that carry a royalty charge to compensate breeders for their work, but access to genetic material is never restricted. The following offerings are a representative sampling of available seed.  Contact Steve Peters for the most current seed listing.




Stella Blue Winter Squash


Dark orange flesh is exceptionally sweet and nutty on a high-yielding Hokkaido/Kabocha cross.  This Cucurbita maxima has light slate blue smooth skin. 95-105 days 





Discovered by Bill Reynolds at a local market in northern CA and selected for organic cultivation at his dryland farm in Humbolt County, Stella Blue is a reliable yielder, offering the market grower an excellent medium sized winter squash with a chestnut-like texture that appeals to discening clientele.









Scarlet Runner Bean

Originally from Mexico, and a favorite in the British Isles, this beautiful, long-producing climber is great eating as a snap bean, in the green shell stage, or as a dry bean. Brilliant red-orange flowers attract hummingbirds and butterflies. Excellent quick screen. 90-95 days to dry stage.


Lemon Cucumber



Unusual spherical fruit with thin tender skin and sweet/tart succulent flesh, this is a traditional  backyard favorite for fresh eating. A reliable yielder of 2-3" diameter juicy yellow cukes. Great market variety. 70-75 days


Shiraz Tall Top Beet


This delicious improved dual-purpose beet was developed for organic production, and shows significant resistance to rhizoctonia dry rot. As the name implies, the tops are especially tall and sturdy, and make a wonderful steamed green. It's the result of a five-year breeding collaboration between Organic Seed Alliance crop scientist Dr. John Navasio and organic seed farmers Randy Carey (OR) and Bill Reynolds (CA). 55-60 days


Dark Star Zucchini


Proven superior to hybrid varieties on large organic farms, this drought and frost resistant variety has a sturdy, open habit with 30% more leaf area, and a deep root systems, resulting in strong, healthy, easily harvested plants; a boon to the organic grower. Straight, faceted, glossy dark fruits of high lutein content.  Long harvest window from vigorous plants. 50-55 days




A collaboration between John Navazio, Steve Peters, and Bill Reynolds, perfected on Bill’s dryland farm in northern CA. Bill credits the remarkable qualities of this break-away variety to his dry farming technique.

                                                                                                        A dozen years later, Bill examines his                Dark Star grown in a trial at Full Belly Farm in California's Capay Valley, where it exhibits more vigor under disease stress than their standard hybrid variety. Continuing trials and selections in different environments lead to further crop improvements.



Dragon Carrot

With deep red-violet skin and yellow-orange interior, this is the best tasting purple carrot on the market, with a bit of spiciness. This is another excellent variety bred by John Navazio and selected by skilled Colorado seed farmer Rich Pecoraro. Strong tops for good bunching.  70-80 days


Contact Steve Peters for the most current seed listing and prices. Seed available in quantities from one ounce to ten pounds for most varieties.

Shiraz Tall Top Beet Breeding Project

Seed Revolution Now! is all about promoting crop breeding for organic conditions. This installment is the tale of a successful breeding project in which we were involved.

As we've stated, open-pollinated (OP) traditional breeding holds the key to a broad spectrum of genetic traits, including improved flavor and nutrition, storage ability,  resistance to diseases and pests and other valuable characteristics. What is missing is a concerted breeding effort to carefully select for these attributes.


In the early 2000's Steve Peters was involved in a breeding project that drew together crop scientists from the Organic Seed Alliance (OSA), organic seed growers, and seed retailers in an effort to create a better table beet for organic cultivation. The goal of the group was to develop a genetically elastic phenotype displaying heterotic vigor, good performance under organic conditions, and acceptance in the marketplace. The picture above shows the result after about five years of breeding: Shiraz Tall Top.


One of the main concerns of beet growers is Rhizoctonia solani, or Rhizoctonia dry rot, a fungal disease. The photo above shows the typical rough, pocked skin of an infected beet, rendered unsalable by the disease. One of the goals of this breeding project was to develop genetic resistance to this common pathogen.


Before the collaborative effort began, OSA plant breeder Dr. John Navazio spent several seasons developing the base population of a new beet variety by cross-pollinating three genetically distinct heirloom beet varieties, each of which held certain desirable traits. His familiarity with many varieties made his contribution particularly valuable.

Beets are in the Amaranthaceae family, related to spinach and chard. This root crop is a biennial, and requires two growing seasons in the ground to go to seed. Roots may be pulled after the first season for evaluation, and the best ones stored over the winter in a cool (32-35 F) and moist (90% RH) environment.


The next step was to grow this promising OP population side-by-side with another high-quality OP beet and the leading commercial F1 hybrid variety, for a comparison trial. The field used was deliberately chosen because it was already infested with Rhizoctonia. Each variety planting was replicated four times across the plot to eliminate field effects from soil and water variation. Over 3000 plants of each variety were grown.


The beets were pulled at market-size maturity, and laid out for observation. Traits evaluated included root smoothness (Rhizoctonia-resistance), root shape, and tops quality and vigor. Here, left to right, John Navazio, farmer Randy Carey, and farmer Tim Franklin, with researcher Micaela Colley (photographer), and seed company representative Steve Peters not shown.


To the left is the standard table beet, Red Ace, an F1 hybrid variety. On the right is an early generation of the Shiraz project. Note the extra length of the Shiraz tops and the nice smooth skin and rounded shape, making it an excellent dual-purpose vegetable.

Here are the three varieties that were trialed. From left to right: Red Ace F1 Hybrid, Pronto, and the breeding population that was to become Shiraz. It was determined that the Shiraz was potentially a superior beet to existing commercial varieties, and was worth developing.

From the original 3000+ roots of Shiraz, the very best 500 (16%) individual roots were chosen to be placed in cold storage and replanted the following spring in a different location. The roots were replanted in a disease-free field on the same farm, to ensure the best possible outcome for seed production. The resultant seed was harvested that fall.


Farmer Randy Carey discusses beet selection for Shiraz grow-outs with seed technician and researcher Emily Skelton at his Oregon farm.


In this early generation of Shiraz, notice that we have good healthy tops and smooth-skinned roots, but the form is more heart-shaped than round. This was improved in subsequent generations.

The following summer, we repeated the process, planting the newest generation of seed on disease-infested ground once again, for yet another hard selection. Ten thousand roots were grown, and only 700 (7%) were saved to be replanted. The following year seed was collected from the replanted selected roots.

Each generation was compared to Red Ace for quality evaluation. While root shape uniformity was a little better in Red Ace, Shiraz had significantly smoother roots and larger and more vigorous tops. At this point it was deemed ready for production.


After the original selection process was completed to the satisfaction of the collaborators,   it was sent to anther certified organic seed grower, farmer Bill Reynolds in Northern California (left, shown with John Navazio), to multiply the seed to commercial quantities.


As an open-pollinated strain, Shiraz offers the opportunity for continued selection for further improvements. These might include adaptations to local bioregions, more disease resistance, improved interior color, or higher sugar content. For anyone interested in pursuing crop breeding and vegetable seed production, Dr. Navazio's recent book, The Organic Seed Grower is an invaluable resource.

For observation of interior characteristics, a vertical wedge may be sliced from a beet root (not a horizontal slice as shown above!), and a beet showing the desired traits can still be stored and replanted successfully.


After flowering and going to seed, plants are allowed to dry before cutting. It is important, however, to harvest before the seed "shatters" and is lost to the ground. Harvest just before fully dry, and finish drying on a tarp. 


Beet seed may be hand-threshed from the chaff, and cleaned with simple winnowing and screening in a small-scale production. Seed should be stored in a dark, cool and dry environment. It should remain viable for at least five years.


Shiraz Tall Top Beet is a valuable new cultivar for organic gardeners and farmers. It is a good example of how OP breeding can be accomplished by anyone willing to put in the effort.

The recipe for success in OP crop breeding includes:
  • A knowledge of available genetic resources containing desired traits
  • Farmer participation in the selection process
  • A sufficiently large population to allow for strict selection criteria
  • Growth under intense disease pressure to allow selection of the best adapted plants
