Sugarcane Cultivars Descriptive Fact Sheet: 'CPCL 97-2730' and 'CPCL 00-4111'

Hardev Sandhu and Wayne Davidson

'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 2018 Sugarcane Variety Census (VanWeelden et al. 2019) 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.

'CPCL 97-2730'

'CPCL 97-2730' is ranked fifth based on its total acreage in Florida (VanWeelden et al. 2019). 'CPCL 97-2730' was released for sand. It currently occupies 13.8% of the total sugarcane area on sandy soil (110, 787 acres). It is also planted on approximately 2.2% of total sugarcane area on muck soil (264, 855 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 fourth based on its total acreage in Florida. It was released for muck soil and is currently cultivated on approximately 7.3% of total sugarcane area on muck soil and less than 3.1% 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.
