Sugarcane Cultivars Descriptive Fact Sheet: CPCL 97-2730 and CPCL 00-41111

Hardev Sandhu and Wayne Davidson2

CPCL 97-2730 (Milligan et al. 2009) and CPCL 00-4111 (Glynn et al. 2011) were developed through the cooperative agreement among the United States Department of Agriculture (USDA) Sugarcane Field Station in Canal Point, the UF/IFAS Everglades Research and Education Center in Belle Glade, and the Florida Sugar Cane League in Clewiston. ‘CPCL’ indicates that the cultivars’ crosses were made at the US Sugar Corporation in Clewiston (CL), and selection at different stages was carried through the cooperative breeding and selection program based at Canal Point (CP). Both are emerging sugarcane cultivars in Florida with rapid expansion in last couple of years. CPCL 97-2730 and CPCL 00-4111 were ranked among the top 10 sugarcane cultivars in Florida in the 2015 Sugarcane Variety Census (VanWeelden et al. 2016) based on their total acreage. High biomass yield and better rust resistance greatly improve the chances of the cultivars’ adoption by growers. This fact sheet provides basic information (Table 1) and yield and disease information (Table 2) about CPCL 97-2730 and CPCL 00-4111 to assist growers in decision-making related to further expansion of these cultivars.

1 Economic index is the dollar value of crop on per acre basis. It is calculated based on sugar yield, price of raw sugar, and harvesting and milling costs.

2 Bru1 is the name of the gene that provides resistance against brown rust disease.

3 SCMV stands for Sugarcane Mosaic Virus, which causes sugarcane mosaic disease.

4 RSD stands for ratoon stunting disease.

5 SCYLV stands for Sugarcane Yellow Leaf Virus, which causes yellow leaf disease.

Disease ratings: R=Resistant; MR=Moderately resistant; MS=Moderately susceptible; S=Susceptible

CPCL 97-2730

CPCL 97-2730 is ranked ninth based on its total acreage in Florida (VanWeelden et al. 2016). CPCL 97-2730 was released for sand. It currently occupies 7.6% of the total sugarcane area on sandy soil (88,206 acres). It is also planted on approximately 1% of total sugarcane area on muck soil (312,345 acres). CPCL 97-2730 is resistant or moderately resistant to most of the sugarcane diseases (especially rust) in Florida, which is very important for its expansion to larger acreage.

CPCL 00-4111

CPCL 00-4111 is ranked tenth based on its total acreage in Florida. It was released for muck soil and is currently cultivated on approximately 3% of total sugarcane area on muck soil and less than 1% on sandy soil. High tonnage and moderate resistance to brown rust (caused by Puccinia melanocephala) and orange rust (caused by Puccinia kuehnii) are positive qualities that may contribute to expansion of this cultivar’s acreage. However, CPCL 00-4111 is also susceptible to smut and scald, which are of some concern for sugarcane cultivation on muck soils.
