Perennial sunflower - a perennial oil and seedcrop developed through backcrossing genes with wild sunflower. Perennial grain - more extensive root systems allow for more efficient water and nutrient uptake, while reducing erosion due to rain and wind year-round. Perennial rice - currently in the development stage using similar methods to those used in producing the perennialized sunflower, perennial rice promises to reduce deforestation through increases in production efficiency by keeping cleared land out of the fallow stage for long periods of time.[11]
