Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.

Life on earth is facing unprecedented challenges from global warming, war, and mass extinctions. The plight of seeds is a less visible but no less fundamental threat to our survival. Seeds are at the heart of the planet's life-support systems. Their power to regenerate and adapt are essential to maintaining our food supply and our ability to cope with a changing climate. In Uncertain Peril, environmental journalist Claire Hope Cummings exposes the stories behind the rise of industrial agriculture and plant biotechnology, the fall of public interest science, and the folly of patenting seeds. She examines how farming communities are coping with declining water, soil, and fossil fuels, as well as with new commercial technologies. Will genetically engineered and "terminator" seeds lead to certain promise, as some have hoped, or are we embarking on a path of uncertain peril? Will the "doomsday vault" under construction in the Arctic, designed to store millions of seeds, save the genetic diversity of the world's agriculture? To answer these questions and others, Cummings takes readers from the Fertile Crescent in Iraq to the island of Kaua'i in Hawai'i; from Oaxaca, Mexico, to the Mekong Delta in Vietnam. She examines the plight of farmers who have planted transgenic seeds and scientists who have been persecuted for revealing the dangers of modified genes. At each turn, Cummings looks deeply into the relationship between people and plants. She examines the possibilities for both scarcity and abundance and tells the stories of local communities that are producing food and fuel sustainably and providing for the future. The choices we make about how we feed ourselves now will determine whether or not seeds will continue as a generous source of sustenance and remain the common heritage of all humanity. It comes down to this: whoever controls the future of seeds controls the future of life on earth. Uncertain Peril is a powerful reminder that what's at stake right now is nothing less than the nature of the future. "With Uncertain Peril, Claire Hope Cummings offers an indispensable contribution to the debate over biotechnology. She rightly focuses our attention on the seed, and what its privatization and manipulation may mean for the future of food." -Michael Pollan, author of In Defense of Food and The Omnivore's Dilemma "Our current approach to industrial agriculture will someday seem so bizarre that our descendants won't understand what we were thinking. This fine volume provides the details of the way we do things now-and the keys to getting towards a farming future that might actually work." -Bill McKibben, author Deep Economy "As agriculture continues to industrialize and globalize, more and more of the seeds farmers plant every year are owned by multinational corporations. And with the corporate focus on effeciency and rational product lines, monocultures continue to grow. Our society has not thought hard enough about whether this is the kind of agricultural system we want. Fortunately, along comes Claire Cummings with this timely and valuable book, to do a lot of important thinking for us. I hope everyone reads it." -John Seabrook, The New Yorker "Claire Hope Cummings has written the clearest analysis and overview of the biotech seeds debate I've ever encountered. Writing with passion, she tells the story of seeds as not only the first link in the food chain but also as our only hope for food security in the midst of global warming. I commend Uncertain Peril to anybody who wants to understand who owns, controls, and is directing the fate of our seeds." -Pat Mooney, author of Shattering and Executive Director of the ETC Group "Uncertain Peril gives us passionate and persuasive reasons why we need more public disc
