‘CP 06‐2400’ (Reg. No. CV‐159, PI 670018) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA–ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and released to growers for organic (muck) soils in Florida in October 2013. CP 06‐2400 was selected from a polycross made at Canal Point, FL, on 16 Jan. 2004 with cultivar CP 94‐1100 as the female parent. The male parent could be any one of the clones used in the polycross. CP 06‐2400 was released because of its high cane and sucrose yields and acceptable commercial recoverable sucrose on 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), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E (mosaic), ratoon stunt (caused by Leifsonia xyli subsp. x yli Evtsuhenko et al.), and smut [caused by Sporisorium scitamineum (Syd.) Piepenbring et al.] in Florida. Based on results of 17 harvests of three crops (plant cane, first ratoon, and second ratoon) in the final‐stage replicated yield trials conducted at six locations on muck soils and compared with a reference cultivar CP 89‐2143, CP 06‐2400 had 38.2% higher cane yield and 26.4% higher sucrose yield ( P < 0.01). CP 06‐2400 ranked second to third best for freeze tolerance among 21 genotypes field tested for temporal sucrose deterioration.
