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 00-950 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. It was released as a commercial variety in the spring of 2007. In 67 harvested trials, HoCP 00-950 produced 5% more sugar, and had 6% higher sugar content than the industry standard, ‘HoCP 96-540.’ In three maturity tests harvested multiple times across the breadth of the 2006-2007 harvest seasons, HoCP 00-950 averaged greater than a 20% higher sugar content than HoCP 96-540, with its greatest advantage being at the beginning of the harvest season. HoCP 00-950 is resistant to brown rust, smut, leaf scald, and mosaic diseases. It is susceptible to the sugarcane borer, and should not be planted in areas where pesticide use is restricted. The early maturity characteristic of HoCP 00-950 provides growers with a variety that can produce profitable sugar yields early in the milling season without the need to apply a chemical ripener.

Technical Abstract: HoCP 00-950 sugarcane was selected from progeny of the cross HoCP 93-750 x HoCP 92-676 made at Canal Point, Florida. HoCP 00-950 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 2007. In 67 combine-harvested trials, HoCP 00-950 produced 5% more sugar, and had 6% higher sugar content than the industry standard, and has exhibited a yield advantage over HoCP 96-540 in both plant and ratoon crops. HoCP 00-950 is not closely related to LCP 85-384 or HoCP 95-540, the two most dominant varieties in Louisiana’s sugar industry. HoCP 00-950 is a very early maturing variety. It is resistant to brown rust, smut, leaf scald, and mosaic diseases. It is susceptible to the sugarcane borer, and should not be planted in areas where pesticide use is restricted. HoCP 00-950 will be maintained at the USDA-ARS Southern Regional Research Center’s Sugarcane Research Unit, located at Houma, Louisiana, for five years. The early maturity characteristic of HoCP 00-950 provides growers with a variety that can produce profitable sugar yields early in the milling season without the need to apply a chemical ripener.
