Interpretive Summary: Sugarcane is grown on organic (muck) 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, but only rarely are such cultivars identified. Experimental data of CPCL 02-1295 suggest that it is one of these rare cultivars. On muck soils, the three-crop mean cane yield and sucrose content of CPCL 02-1295 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 CPCL 02-1295 were compared. Its high cane yield and acceptable sucrose content resulted in a sucrose per hectare yield and an economic index on muck soils that were both higher for CPCL 02-1295 than for CP 72-2086 and similar for CPCL 02-1295 and CP 89-2143. On sand soils, the sucrose content of CPCL 02-1295 was similar to that of CP 78-1628, the reference cultivar for sand soils; and CPCL 02-1295 and CP 78-1628 had similar cane yields. Also, the yield of sucrose per hectare and the economic index of CPCL 02-1295 and CP 78-1628 were similar on sand 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. CPCL 02-1295 has shown adequate resistance for commercial production in Florida to brown rust, sugarcane mosaic virus, and smut. CPCL 02-1295 is moderately susceptible to orange rust and leaf scald and is susceptible to sugarcane yellow leaf virus as are almost all sugarcane cultivars in Florida. The commercial release of CPCL 02-1295 makes available to Florida growers a cultivar that maintains high yields in the presence of diseases, and therefore should help to continue providing the U.S. an affordable and stable sugar supply. Additionally, CPCL 02-1295 may be tested by farmers in Central America, who grow mostly Canal Point (CP) cultivars. CPCL 02-1295 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 September 2011.

Technical Abstract: Research to develop ‘CPCL 02-1295’ sugarcane (a complex hybrid of Saccharum spp.) was initiated by the United States Sugar Corporation (USSC), and completed cooperatively by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CPCL 02-1295 was released to growers in Florida in 20 Sept. 2011. CPCL 02-1295 was selected from a cross of ‘CP 88-1762’ × genotype ‘CL 91-1637’ made at Clewiston, FL on 26 Dec. 2001. The female parent, CP 88-1762, is a major commercial cultivar in Florida due to its high sucrose yields on both muck and sand soils, occupying 23.1% of the total FL acreage in 2009. The male parent, CL 91-1637, reached the final testing stage of the USSC breeding program due to high biomass yields but was never released commercially due to low sucrose content. CPCL 02-1295 is resistant to brown rust (caused by Puccinia melanocephala H. & P. Sydow), Sugarcane mosaic virus strain E (mosaic) and smut (caused by Ustilago scitaminea (Sydow & P. Sydow). CPCL 02-1295 is moderately susceptible to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and orange rust (caused by Puccinia kuehnii E.J. Butler). CPCL 02-1295 is recommended for both organic (muck) and sand soils in Florida where it had high plant cane tonnage and sucrose yields in both soil types in our tests.
