Registration of ‘CP 15-1407’ sugarcane for muck soils

The complex hybrid sugarcane (Saccharum spp.) cultivar ‘CP 15-1407’ (Reg. no. CV-217; PI 704105) was made available to growers in June 2022 for cultivation on muck soils in Florida. This development took 10 years thanks to collaborative research by the USDA–ARS, the Florida Sugar Cane League Inc., and the University of Florida. It started at Canal Point (CP) as a bi-parental cross between ‘CP 08-1110’ (female) and CP 05-1616 (male). Due to its high stalk weight, adequate disease resistance, higher recoverable sugar, and equivalent cane yield to best check ‘CP 96-1252’ on muck soils, the Florida Sugarcane Variety Committee recommended releasing CP 15-1407. It has demonstrated resistance to brown rust, orange rust, sugarcane mosaic, smut, leaf scald, and ratoon stunt and is moderately susceptible to yellow leaf. In late-stage, on-farm yield trials, CP 15-1407 stalk weights were 27.8% heavier than that of CP 96-1252, while cane yields and economic index (EI) did not differ from CP 96-1252. Florida sugarcane output and crop sustainability are predicted to benefit from CP 15-1407's sustained cane production capacity and proven disease resistance.
