‘John Navazio has written a fantastic guide for organic seed breeders and producers. He has taken organic seed production to a higher level with extensive information on selection, genetic integrity, isolation distances, and seedborne diseases. Although his focus is on plant breeders and commercial growers, much of the information is also applicable to small-scale farms producing seed for on-site use.’ — Suzanne Ashworth, author of Seed to Seed


John Navazio breeds genetically resilient, open-pollinated leafy greens and root crops for regenerative farming practices at Johnny’s Selected Seeds in Maine. His crops include carrots, onions, radicchio, purple-sprouting broccoli, and Swiss chard. John’s work focuses on developing varieties with robust, vigorous growth, broad resistance to disease and environmental stress, and superior culinary quality. He also concentrates on increasing the reproductive vitality of his varieties and their ability to produce good seed yields. To that end, he works with a diverse group of organic seed growers across North America to produce the highest-quality seed.
