0PI 674794'Frontiere'Oryza sativa L. Louisiana, United StatesPVPONot Available2015DEVELOPEDCultivarFrontiere is a very early, semidwarl long-grain rice cultivar that was developed from induced mutation by means of cellular selection using parental material from the cultivar Cypress. Frontiere averages 91.5 cm in height, which is similar to Cypress. Frontiere averages 85 days from emergence to 50% heading, which is similar to Cypress and 3 days later than Cocodrie. The leaves are dark green in color and display an erect leaf angle. It has a purple apiculus. Its lemma and palea are gold at maturity and gold furrows and straw background, glabrous and typically non-awned. The brand is light brown and non-glutinous, with an average of 21.8% amylose content. The grain has intermediate gelatinization temperature. Frontiere has an average protein content of 11 %, about 53% improvement from the protein content of the original line (Cypress) from which it was derived (mutated). It was developed at the Rice Research Station in 2006 (ID-58120018). The high protein rice cultivar is a very early, semidwarf long grain. Frontiere closely resembles the rice variety Cypress and, therefore, differs with other rice cultivars. Its main distinctness to Cypress and other rice cultivars is its high grain protein content. Despite its close similarity with cultivar Cypress in amylose content, its grain has distinct cooking characteristics due to its increased protein content.1926840PI 674794
