Perennial grains research
When The Land Institute and our allies succeed, a farm will no longer have to be an ecological sacrifice zone; rather, it can provide food while at the same time it protects soils, water and biodiversity. We need the missing link: perennial grain crops. And as those new crops are being developed, plant breeders, agro-ecologists and farmers will be working out strategies for growing them in mixtures, to recapture the ecological soundness of pre-agricultural landscapes.
The genetic raw material is out there, ready to be put to use. Plants now in field plots and on greenhouse benches at the Land Institute form the foundation of breeding programs that will, given decades of work, turn out perennial grain crops. Most of the current genetic and breeding effort is going into the following species and species hybrids:
Wheat can be hybridized with several different perennial species to produce viable, fertile offspring. We have produced thousands of such plants. Many rounds of crossing, testing and selection will produce perennial wheat varieties for use on the farm.
Intermediate wheatgrass (Thinopyrum intermedium) is one of those perennial relatives of wheat. It is also a potential grain crop on its own. We established genetically diverse populations and have begun selection for crop-like traits.
Grain sorghum is a drought-hardy feed grain in North America and a staple human food in Asia and Africa, where it provides reliable harvests in places where hunger is always a threat. It can be hybridized with perennial species Sorghum halepense. We have produced large plant populations from hundreds of such hybrids.
Illinois bundleflower (Desmanthus illinoiensis) is a native prairie legume that fixes atmospheric nitrogen and produces abundant protein-rich seed. It is one of our strongest candidates for domestication as a crop. We have assembled a large collection of seed from a wide geographical area and have initiated a breeding program.
Sunflower is another annual crop we have hybridized with perennial species in its genus, including Helianthus maximiliani, H. rigidus and H. tuberosus (commonly known as Jerusalem artichoke). Breeding work is underway.
There is potential for many more perennial grain species, including maize, Eastern gamagrass, rice, chickpea, millets, flax and a range of native plants. We are studying these and other species but do not currently have staff to initiate breeding programs.
CROSS BETWEEN CORN AND A WILD RELATIVE YIELDS A PERENNIAL CROP
By WALTER SULLIVAN

FOR thousands of years farmers have had to plant a new corn crop every spring. Recently, however, an American-Argentine collaboration bred a perennial variety by crossing corn with a distant wild relative, teosinte, which is native to Central America.
The development has generated great excitement among plant breeders. But perennial varieties of any crop are always much less productive than their annual counterparts. Moreover, the products of the corn-teosinte cross, now in their third season of growth, scarcely resemble what farmers and consumers today know as corn. Still, the achievement holds hope for major increases of food production, especially in developing countries where corn is grown for fodder rather than grain.
The achievement of perennial corn is a personal triumph for Dr. Paul C. Mangelsdorf, for more than 20 years a professor of botany at Harvard University, who is now approaching his 83d birthday at the University of North Carolina. It was he who supplied the crossbred seeds from which Julian Camara-Hernandez, professor of agricultural botany at the University of Buenos Aires, has grown the perennial corn and other hybrids.
Chromosome Counts Aided Interbreeding
The possibility of breeding perennial corn was suggested in 1979 by Dr. Hugh H. Iltis, a botanist at the University of Wisconsin in Madison, when he described in the journal Science the discovery of a perennial teosinte whose chromosome count was similar to that of corn.
When plant or animal cells divide, the genetic material in their nuclei organizes itself into a characteristic series of bundles known as chromosomes. Corn has 20 chromosomes, as does the annual form of teosinte. Hence in Mexico, where teosinte sometimes grows near corn patches, the plants may interbreed, exchanging genetic properties.
As long ago as 1910, Dr. Albert Hitchcock of the Smithsonian Institution found a perennial teosinte near a railroad station in Jalisco State, but it could not be crossbred with corn because it had twice as many chromosomes. Furthermore, for a half century after 1921 no more of the plants were seen.
Then, in 1978, Rafael Guzman, a botany student at the University of Guadalajara in Jalisco, discovered a surviving patch. On an expedition higher into the mountains Mr. Guzman, Dr. Iltis and others then found a large plantation of perennials at a height of 7,500 feet and the plants, like corn, proved to have 20 chromosomes.
This new species, they reported in Science, ''should provide geneticists and maize breeders with a potentially valuable source of germ plasm, and may lead to the development of perennial maize.''

This is an article by Wes Jackson that was previously published by Solutions Journal. We have included a few Campfire questions at the end.
The Trouble with Agriculture
Across the farmlands of the U.S. and the world, climate change overshadows an ecological and cultural crisis of unequaled scale: soil erosion, loss of wild biodiversity, poisoned land and water, salinization, expanding dead zones, and the demise of rural communities. The Millennium Ecosystem Assessment (MEA) concludes that agriculture is the “largest threat to biodiversity and ecosystem function of any single human activity.”1 Up to 40 percent of global croplands are experiencing soil erosion, reduced fertility, or overgrazing.2 It is likely that agricultural acreage worldwide will expand over the next two to three decades, especially as the human population increases to eight to 10 billion people. The same thing that drives climate change helps drive the agricultural crisis—cheap fossil fuel.
In the U.S., commodity subsidies that focus on bushels per acre, an industrial model that much of the world wants to imitate, continue to drive this increasingly unsustainable agricultural economy. Over the past century, the number of farms in the U.S. has declined as the average farm size has increased. At the same time, the number of commodities per farm—such as corn, wheat, barley, soybeans, alfalfa, tobacco, potatoes, pigs, and chickens—has decreased from an average of five to just one product.3 American agriculture is guided by five-year farm bills and heavily entrenched subsidies. Export policy is the driver designed to offset our nation’s balance of payments deficit, which includes the purchase of foreign oil.
We need a long-term, conserving vision to counteract these trends. Five-year farm bills should be mileposts in a 50-year journey to end degradation of our agricultural capital. Where do we begin? The United States is a big country, and the ecological mosaic is daunting. There are the soils of the upper Midwest, deep and rich in nutrients from the Pleistocene’s scouring ice and watered by the moisture favorably blown from the Gulf of Mexico. What have we done with this land? Soil erosion, nitrogen fertilizer, and pesticides have seriously degraded this gift of good land, the best contiguous stretch in the world. In California, rich valleys and reliable snow pack in a Mediterranean environment lessen the problem of soil erosion. But there is spraying, salinization, accumulation of toxins in the delta, and loss of farmland to sprawl.
One could continue the inventory, but the point is that each region has its own problems and opportunities. We must acknowledge that all successful corrections will be local. And that plays to an often-overlooked point: The decline of fossil fuels will require a higher eyes-to-acre ratio, which means more farmers on the land. Cultural and ecological adaptation become one subject.
Looking broadly, the USDA and the secretary of agriculture should see that our first order of business should be to prevent our soils from eroding and declining in quality—they are the source of most of the nutrients that feed us. If our soils are protected, the water falling on them can be protected and properly used on its trip to the atmosphere, ocean, or aquifer. The United States has about 400 million acres of cropland, with around 36 million acres placed in the Conservation Reserve Program.4,5 The secretary of agriculture must look at the aggregate use of these croplands. At any one time, 80 percent of that land grows annual crops. The other 20 percent is in perennials, such as pastures or hay, although, to be clear, sometimes in a rotation with annuals such as corn or sorghum.
Such an overview quickly draws one’s attention to the core of what might be called “the problem of agriculture”: essentially all of the high-yield crops that feed humanity—including rice, wheat, corn, soybeans, and peanuts—are annuals. With cropping of annuals, alive just part of the year and weakly rooted even then, comes more loss of precious soil, nutrients, and water.
The Land Institute
Summary of the possible. Protecting our soils with perennials.
A. 2010: Hay or grazing operations will continue as they exist. Preparations for subsidy changes begin.
B. 2015: Subsidies become incentive to substitute perennial grass in rotations for feed grain in meat, egg, and milk production.
C. 2020: The first perennial wheat, Kernza™, will be farmer-ready for limited acreage.
D. 2030: Educate farmers and consumers about new perennial grain crops.
E. 2045: New perennial grain varieties will be ready for expanded geographical range. Also potential for grazing and hay.
F. 2055: High-value annual crops are mainly grown on the least erodible fields as short rotations between perennial crops.

The flour makes a light dough and the pancakes taste just a tad sweeter than ordinary wheat flour. It is Jackson’s hope that within ten years, he and his staff can develop Kernza ™ for use in commercially manufactured foods. It is exceptionally high in some nutrients known to be important to human health and deficient in many modern diets: Omega 3 fatty acids, calcium, lutein, and betaine. It is particularly high in folate, important for preventing stroke, cancer, heart disease and infertility. Folate is also believed to be important for maintaining good mental health in old age. My mind generally glazes over when reading about nutrient values of various foods so that folate might come in handy. To me the important thing is that for once something that is good for me tastes good too. Kernza ™ does not have enough gluten in it to use alone for leavened breads, but as more and more crosses are made with it and regular wheat, all things are possible.

WASHINGTON -- The time could come when farmers aren't getting on their tractors every spring to plant their crops, or even plowing their fields, exposing those fields to erosion.

At least that's the vision of a few scientists -- and a senior Obama administration official -- who want to develop perennial versions of corn, wheat, rice and other crops that don't need to be planted every year and wouldn't cause the environmental damage linked to growing conventional grains.
"Getting to the yields of today's corn in central Iowa with a perennial corn will not happen quickly, but I do think it is possible," said Ed Buckler, an Agriculture Department scientist at Cornell University in New York. "With prior technology, it would have taken 100-plus years. Now, I think we can do it in 20 years with a concerted effort."
The idea of replacing annual food crops with perennials has long been on the fringe of agricultural research, largely confined to a private facility in Kansas called the Land Institute.
But Deputy Agriculture Secretary Kathleen Merrigan, a lead author of the nation's organic food standards during a previous stint at the USDA, has been talking up perennial grains as a promising way to produce food with less environmental impact.
"We're interested in the development of perennial grains -- big seeds, high yields," she said at a recent food-policy conference in Washington. "These plants with deep roots to hold the soil in place and pick up water and nutrients year-round could reduce the demand for water over the more typical annual grain that produce a big harvest but die each year."
She noted that the USDA is financing some initial research into the genetic basis of perennialism and developing the genetics for breeding perennial crops.
However, perennial crops have little appeal to today's agribusiness, including seed giants like Pioneer Hi-Bred and Monsanto.
"They depend on selling a lot of seed every year," said Bill Beavis, interim director of Iowa State University's Plant Sciences Institute. "I'm not sure the perennials ever catch up just because they don't have the resources" in terms of research funding.
So far, the USDA is spending nothing close to what scientists say the research needs.
An article last year in the journal Science co-authored by Buckler and scientists at the Land Institute and elsewhere, said perennial grain crops could be ready in 20 years but that it would take a monetary commitment comparable to what the government is now putting into developing biofuel crops.
The USDA has asked Congress for $1 million in fiscal 2012 for perennial grain or sunflower research at its own labs, a slight increase over this year's money. In 2009-10, the department provided about $1.5 million in grants for perennial grains research at the Land Institute and a few universities.
A serious effort to breed perennial corn crops would require spending $1 million to $2 million for five years to identify the genes necessary for perennialism, Buckler said. After that, $10 million to $20 million a year and dozens of scientists would be needed to breed a perennial corn that could eventually be commercialized, he said.
With deep roots, perennial crops would prevent top soil from washing away, lessening the need for nitrogen fertilizer and reducing the amount of farm chemicals that pollute rivers and streams.
"Before agriculture, 95% of the Earth's ice-free land surface was covered by mixtures of perennial plants," said Stan Cox, senior research scientist at the Land Institute, which has focused on crops such as wheat because of the center's location in Kansas. "On land like that, you see virtually no erosion."
It's a steep challenge to develop perennials that can produce grain at the rate of annuals, which have fed humans for millennia. There are tradeoffs when breeding plants for producing seed, or grain, or for longevity, scientists say. Perennials put much of their efforts into developing roots, rather than seeds.
Still, Buckler said it's theoretically possible to develop perennials that produce even more grain than annuals, based on the fact that perennials have a longer growing season and won't need to re-grow their roots.
Iowa State economist Chad Hart said it will be tough to come up with a perennial crop that can be as attractive to farmers as today's corn. Last year's harvest of more than 12 billion bushels was worth $67 billion. Farmers in Iowa are expected to earn $300 an acre growing corn, meaning that a farmer with 500 acres could make $150,000, after expenses.
"That's a massive crop market," Hart said. "Trying to develop something that will replace even part of that is a massive achievement."
