Abstract
Over three million acres of marginal farm land in the United States are capable of producing guayule rubber. Use of existing strains on these lands would produce 200,000 long tons of natural rubber per year. Plant breeding and process research could raise this to at least 300,000 long tons, or about half of our annual consumption of natural rubber.
