Interpretive Summary: Farmers are constantly wanting cultivar that yield more and are more resistant to diseases. Cybonnet, a semi-dwarf long-grain rice, has grain yield and grain quality of highly excepted cultivars with an improved milling quality. This new cultivar will increase farmers profits by increasing the amount of head rice they get per acre.

Technical Abstract: Cybonnet is a semi-dwarf long-grain rice cultivar originating from the cross Cypress//Newbonnet/Katy made at the Rice Research and Extension Center in 1993. It has been tested in the Arkansas Rice Performance Trials and the Uniform Rice Regional Nursery for four years. It has grain yield, height, and lodging resistance similar to Cocodrie, grain quality similar to Cypress, and blast resistance similar to Katy. It is moderately susceptible to straighthead disorder. The major advantages of Cybonnet are its good grain yield, resistance to lodging, good blast disease resistance, and excellent milling quality. The major disadvantage of Cybonnet is susceptibility to sheath blight.
