Interpretive Summary: The need to remain competitive in a global economy, to cope with shifts in the disease and insect complex, and to reduce the risks associated with becoming overly dependent on a single major commercial variety all highlight the need to continue to develop new, higher-yielding, pest-resistant sugarcane varieties. HoCP 96-540 was developed using conventional cross-breeding techniques through cooperative research by the Agricultural Research Service of the United States Department of Agriculture, the Louisiana Agricultural Experiment Station of the Louisiana State University Agricultural Center, and the American Sugarcane League of the U.S.A., Inc. It was released as a commercial variety in the spring of 2003. HoCP 96-540 has consistently yielded 10-15% more sugar per acre than the dominant variety, LCP 85-384. HoCP 96-540 has shown field resistance in Louisiana to rust, smut, leaf scald, and mosaic diseases. It is susceptible to the sugarcane borer and should not be grown in areas where insecticides cannot be applied. If planted to 50% of Louisiana's sugarcane acreage, HoCP 96-540 could eventually increase grower profits by $30 million annually.

Technical Abstract: HoCP 96-540 sugarcane was selected from progeny of the cross LCP 86-454 x LCP 85-384. HoCP 96-540 was developed through cooperative research by the Agricultural Research Service of the United States Department of Agriculture, the Louisiana Agricultural Experiment Station of the Louisiana State University Agricultural Center, and the American Sugarcane League of the U.S.A., Inc., and was released in the spring of 2003. HoCP 96-540 has consistently yielded 10-15% more sugar per unit area than the principal cultivar, LCP 85-384, in both plant-cane and ratoon crops. HoCP 96-540 is a mid-maturing variety that shows good response to the ripener, glyphosate. HoCP 96-540 has shown field resistance in Louisiana to rust, smut, leaf scald, and mosaic diseases. Like most commercial cultivars, including LCP 85-384, it has exhibited susceptibility to ratoon stunting disease and the sugarcane borer. HoCP 96-540 will be maintained at the USDA-ARS Southern Regional Research Center's Sugarcane Research Unit, located at Houma, Louisiana, for five years.
