Registration of ‘CPCL 00-4111’ Sugarcane. Journal of Plant Registrations. 5(3):325-331. 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 00-4111 suggest that it will yield well in commercial sugarcane fields on muck soils. On muck soils, the three-crop mean cane yield of CPCL 00-4111 was higher than that of CP 72-2086 and CP 89-2143. CP 72-2086 and CP 89-2143 were the reference cultivars against which yields of CPCL 00-4111 were compared. The three-year mean values of sugar content on muck soils of the two reference cultivars and CPCL 00-4111 were usually similar. Its high cane yield and acceptable sugar content resulted in a sugar per hectare yield and an economic index on muck soils that were both higher for CPCL 00-4111 than for CP 72-2086 and CP 89-2143. 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 00-4111 has shown adequate resistance for commercial production in Florida to eye spot, smut, leaf scald, brown rust, orange rust, sugarcane mosaic virus, and ratoon stunting. CPCL 00-4111 is susceptible to sugarcane yellow leaf virus as are almost all sugarcane cultivars in Florida. The commercial release of CPCL 00-4111 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 00-4111 may be tested by farmers in Central America, who grow mostly Canal Point (CP) cultivars. CPCL 00-4111 was developed by a discontinued sugarcane breeding program of the United States Sugar Corporation in Clewiston, FL. It was donated to the USDA-ARS in 2005 when this program was discontinued. The USDA-ARS, the University of Florida-Institute of Food and Agricultural Sciences, and the Florida Sugar Cane League, Inc., cooperatively conduct a sugarcane cultivar development program and after 5 years of testing in this program, CPCL 00-4111 was released in December 2010.
Technical Abstract: Development of ‘CPCL 00-4111’ sugarcane (a complex hybrid of Saccharum spp.) is the latest in a series of commercial sugarcane cultivar releases originating from the United States Sugar Corporation (USSC) and completed by the cooperative Canal Point sugarcane breeding and selection program which included the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CPCL 00-4111, which was released in Florida in December 2010, was selected from a cross of genotype CL 83-3431 X CL 89-5189 made at Clewiston, FL in December 1998. The female and male parents, CL 83-3431 and CL 89-5189 respectively, were proprietary genotypes of USSC. CPCL 00-4111 was released because of its high cane yield and commercial recoverable sucrose (CRS) on organic (muck) soils, and its acceptable levels of resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), smut (caused by Ustilago scitaminea H. & P. Sydow), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and Sugarcane mosaic virus strain E (mosaic), all of which are of economic importance to sugarcane production in Florida.
