Interpretive Summary: Interpretive Summary: Sugarcane is grown on organic and sand soils in a region near Lake Okeechobee in south Florida. This region contributes about 25% of U.S. domestic sugar production. New cultivars are needed that yield well on both soil types and have acceptable profiles of disease resistance. Experimental data of CP 00-2180 suggest that it will yield well on sand soils where sugarcane is grown in Florida. On sand soils, the sugar content of CP 00-2180 was similar to that of CP 78-1628, the reference cultivar for sand soils. CP 00-2180 and CP 78-1628 also had similar per hectare yields of cane and sucrose, but the mean economic index of CP 00-2180 for the three crop cycle was higher than that of CP 78-1628 on sand soils. On organic soils, the three-crop mean yields of cane and sucrose of CP 00-2180 were higher than those of CP 72-2086 and similar to those of CP 89-2143. CP 72-2086 and CP 89-2143 were the reference cultivars against which yields of CP 00-2180 were compared on organic soils. The three-year mean sugar content on organic soils of CP 00-2180 was similar to that of CP 72-2086 and lower than the sugar content of CP 89-2143. CP 00-2180 is not recommended for muck soils due to its low sugar content on these soils. Cultivar resistance and tolerance are the major sources of sugarcane disease control in Florida, but they are challenging to identify and quantify, because plants are growing and therefore exposed to disease pressures all year. CP 00-2180 has shown adequate resistance for commercial production in Florida to eye spot, smut, leaf scald, sugarcane mosaic virus, brown rust, orange rust, and ratoon stunting. CP 00-2180 is susceptible to sugarcane yellow leaf virus, but its high yields in experimental plots were obtained regardless of this susceptibility. The commercial release of CP 00-2180 made available to Florida growers a cultivar that maintains high yields on sand soils in the presence of diseases, and therefore should help to continue providing the U.S. an affordable and stable sugar supply. Additionally, CP 00-2180 may be tested by farmers in Central America, who grow mostly Canal Point (CP) cultivars. CP 00-2180 was developed through cooperative research by the USDA-ARS, the University of Florida-Institute of Food and Agricultural Sciences, and the Florida Sugar Cane League, Inc., and was released in the autumn of 2007.
Technical Abstract: Technical Abstract: ‘CP 00-2180’ (Reg. No. , PI ) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and was released to growers in Florida in September 2007. CP 00-2180 was selected from a self cross of cultivar HoCP 91-552 made at Canal Point, FL in January 1998. Based on its high cane yields and fiber content (16%), HoCP 91-552 was released as a cultivar for bio energy in Louisiana. CP 00-2180 was released and recommended for sand soils in Florida because of its high plant cane and acceptable ratoon per hectare yields of cane and sucrose and commercial recoverable sucrose (CRS) on sand soils, and its acceptable disease reactions to smut (caused by Ustilago scitaminea (Sydow & P. Sydow), brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), leaf scald [caused by Xanthomonas albilineans Ashby, Dowson], Sugarcane mosaic virus strain E (mosaic), and ratoon stunting disease (RSD) (caused by Clavibacter xyli subsp. Xyli Davis) in Florida.
