Technical Abstract: Madison, a new long grain rice cultivar having improved disease resistance has been released by the USDA-ARS Rice Research Unit. This cultivar was developed from a cross between Lemont and Katy. Lemont has been an important long grain variety for commercial production in the southern U.S. due its high yield, milling quality, and semidwarf plant type. Katy is a tall cultivar which is highly resistant to rice blast disease caused by Pyricularia grisea. In 1988, a cross was made between these two cultivars with the objective of incorporating the disease resistance of Katy into the high yield, semidwarf plant type of Lemont. Madison is a semidwarf cultivar that has superior lodging resistance like Lemont. It can be harvested in about 113 days similar to the cultivar Cypress. It is well adapted for production in the southern U.S. rice growing region and has produced grain yields and milling yields similar to that of Gulfmont. Madison is resistant tto all but one of the prevalent pathotypes (IE-1K) of blast that occur in the U.S. It is also more resistant to sheath blight disease caused by Rhizoctonia solani than the cultivars Gulfmont, Cypress and Kaybonnet. Madison has cooking quality similar to other southern U.S. long grain rice varieties, having an amylose content of 21 percent and an intermediate gelatinization temperature.
