Wild rice was an important staple of the indigenous peoples of the Great Lakes region and remains part of many legends and ceremonies. Flowers are in a branching panicle with female (pistillate) flowers at the topand male (staminate) flowers on the lower portion. Cross pollination usuallyoccurs since female flowers emerge first and become receptive and arepollinated before male flowers shed pollen on the same panicle. Wild species of Oryza offer a wide spectrum of adaptive traits and can serve as potential donors of biotic and abiotic stress tolerance.

Native Americans and others harvest wild rice by canoeing into a stand of plants, and bending the ripe grain heads with wooden sticks called knockers, so as to thresh the seeds into the canoe. As a lifelong Michigander and an endangered species biologist by training, Barton finds boundless inspiration in the region’s rich history. The perennial wild species O. longistaminata , which showed large stem diameter, thick stem wall, and high biomass production, is believed to help improve rice lodging resistance ( Khush, 1997 ).
