Registration of 'Jazzman' aromatic long-grain rice. Journal of Plant Registrations. 5:304-308. Interpretive Summary: The demand for aromatic rice has dramatically increased over the past two decades in the United States. There are three major classes of aromatic rice in the U.S. market, which include Jasmine-, Basmati- and Della-types. Most of soft-cooking Jasmine and elongating Basmati rice in the U.S. market is imported, and the volume of such imports is increasing every year. Jasmine aromatic rice, which originated in Thailand and is largely produced there, makes up about 80 percent of U.S. aromatic rice imports. Thai Jasmine rice cultivars are not adapted for production in the United States. Currently, only Jasmine 85, developed at IRRI and released in 1989 by USDA-ARS in cooperation with the Texas Agricultural Experiment Station, is available in the United States. However, it has been grown on very limited acreage because of its off-white grain color and poor milling yield. The development of Jazzman which is well-adapted to the Gulf- and mid-south rice growing regions, should enable the U.S. rice industry to better compete with imports targeted at this high-valued niche market.
Technical Abstract: Jazzman is a U.S.-bred Jasmine-type, soft-cooking aromatic long-grain rice cultivar (Oryza sativa L.) that is glabrous and has no seed dormancy. It was developed from a single cross using a modified pedigree breeding method at the Rice Research Station, Louisiana State University Agriculture Center, Crowley, LA. Jazzman is a high-yielding, moderately early-maturing, conventional height cultivar with good milling, translucent slender grains, and a strong aroma. The average main and ratoon crop yield of Jazzman is 7.8 and 1.5 ton per ha, respectively, and it has head rice yield of 63.6 percent and total milled rice yield of 69.6 percent. It has the typical Jasmine-type cooking quality with the low amylose content, low gelatinization temperature and an average 2-acetyl-1-pyrroline content of 436 ng per g. It is moderately susceptible to sheath blight, bacterial panicle blight and the physiological disorder straighthead, but moderately resistant to blast. Successful development of Jazzman rice, which is well-adapted to the Gulf- and mid-south rice growing regions, should enable the U.S. rice industry to better compete with imports of that target this high-valued aromatic niche market.
