How scientific minds changed toward perennial grains

Early boosters were voices on the fringe: Today, perennial crops are sought by researchers worldwide — including Manitoba

In the early days of kernza — a perennial grain crop related to wheat — plant breeders at The Land Institute in Kansas couldn’t get a government grant to save their lives. “We got very nice compliments on our writing of the grant proposals and harsh criticism on the value of actually doing the work,”

Plant breeder and researcher Doug Cattani was recently recognized by the province 
for innovation in sustainability.

And to think, he could have been an accountant. Plant breeder and researcher Doug Cattani received provincial recognition in October for his work in developing perennial grains. Since 2010, Cattani has worked with Kernza, the trade name for organically produced intermediate wheatgrass, which is being developed for grain production. As a perennial grain, Kernza causes

Making bread — and maybe history too

The first loaves of bread made from Kernza have been gobbled up in Manitoba

You won’t be buying Kernza bread in a Manitoba bakery or grocery store any time soon, but a small group of proponents see it as a sign of things to come. Guests at a small reception at the Tall Grass Prairie Bakery in downtown Winnipeg Nov. 23 were treated to loaves of freshly baked sourdough

Intermediate wheatgrass is the skinny cousin to spring wheat but, of course, you can’t graze the latter and then harvest a grain crop later.

Perennial grain: It’s two crops in one

It’s been a decades’ long search, but researchers believe the finish line is in sight 
for a crop that can be both grazed and then harvested for its grain

As concerns grow over sustainability in modern farming, researchers are looking to the past in search of crops that can both meet the needs of farmers and consumers as well as the environment. Thinopyrum intermedium — commonly known as intermediate wheatgrass — is one of the fruits of that research. It’s been nearly three decades


Crop breeder Doug Cattani is working with a variety of potential perennial crops but says intermediate wheatgrass right now looks the most promising.

Perennial grain crops are one step closer

The goal is to find ways to grow food that will reduce the need 
for fertilizers, herbicides, and annual seed purchase

Seed it once, then sell everything except the combine and just keep harvesting year after year. It might not work out quite that way, but a perennial grain crop that can withstand cold Prairie winters is a little closer to reality for Canadian farmers.
