'Medark', semi-dwarf medium-grain rice cultivar. In: Norman, R.J., Meullenet, J.-F, Moldenhauer, K.A.K., editors. B.R.

Available: http://www.uark.edu/depts/agripub/Publications/researchseries/ Interpretive Summary: The short grain rice, Bengal, grown in Arkansas is susceptible to blast, brown spot and straighthead which reduces yield. The new semi-dwarf medium-grain rice, Medark, has a greater resistance to the above problems while maintaining the yield and grain quality of Bengal. The new cultivar will be of great benefits to farmers by increasing their yield and thus their profit.
Technical Abstract: Medark is a semi-dwarf medium-grain rice cultivar originating from the cross Bengal/Short Rico 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, grain quality and lodging resistance similar to Bengal. The major advantages of Medark are its improved resistance to blast, brown spot and straighthead. The major disadvantage of Medark is susceptibility to panicle blight.
