Researchers at The Land Institute reported about a crop with very small
cereal grains but seems to be immortal, giving hope to the future of
agriculture.

The crop, known as Kernza, is a hybrid derived from wheatgrass. It was
developed by scientists to withstand the drastic effects of climate change.
It is a penennial grain, which does not need to be replanted after harvest
season, because the plant can regrow repeatedly while its roots grow deeper
under the ground. This helps decrease soil carbon emission which occurs
during harvesting and sowing of seeds.

To date, Kernza is planted on 500 hectares of land in Kansas. A food
corporation made a breakfast cereal prepared from Kernza and also providing
funding to Land Institute for large-scale production of the cereal crop.
Another international company brewed a new kind of beer using Kernza. Food
hubs in the U.S. are also using Kernza flour for pasta, bread, and pizza and
the consumers' feedback is favorable.
