Abstract
A new and distinct gamagrass, which is the product of a cross between gamagrass, Tripsacum dactyloides , and a Zea - Tripsacum recombinant. This plant is fertile, has proven to be cross compatible with Zea mays L. and Tripsacum sp., and offers an avenue to expand the gene pool for commercial corn varieties. The instant plant is perennial with well developed rhizomes, aerenchyma tissue in its roots, high carbohydrate and sugar content, abundant seed and prolific vegetation production, traits that give it improved value as a forage crop and biofuel feedstock.
