Presidio rice - a new long grain rice with improved ratoon crop potential and milling yield. Texas Rice, Highlighting Research in 2005. p. XI. Technical Abstract: USDA-ARS and TAES have announced the release of a new long grain cultivar for production in the South. Presidio rice was developed from a cross of a Jefferson sibling with Maybelle and Rosemont. Presidio is similar to Cocodrie in height and maturity. It has good sheath blight tolerance, similar to that of Saber and better than Cocodrie. Presidio possesses one of the two major resistance genes found in Jefferson which conveys resistance to five of the nine races of blast commonly found in the South. The most important features of Presidio are that it has greater ratoon crop potential than Cocodrie and has high milling quality like Cypress.
