‘CP 03-1912’ (Reg. No. CV-145, PI 660674) sugarcane (a complex hybrid of spp.) was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugarcane League, Inc.,and was released to growers in Florida on 18 Feb. 2011. CP 03-1912 was selected from the cross X00-656 (genotypesCP 92-1167 × CP 95-1039) made at Canal Point, FL on 20 Dec. 2000. Both parents were advanced to the final selection stage (stage 4) of the Canal Point (CP) sugarcane cultivar breeding and selection program (CP program) but not considered for commercial release. CP 03-1912 was tested in stage 4 only on sand soils in Florida and was released for these soils because of its high cane yield and acceptable commercial recoverable sucrose (CRS); its resistance to brown rust (caused by H. & P. Sydow), orange rust (caused by E.J. Butler), and strain E (the causal agent of mosaic); and its moderate resistance to leaf scald [caused by (Ashby) Dowson], smut (caused by H. & P. Sydow), and ratoon stunt (caused by subsp. Evtsuhenko et al.) in Florida. CP 03-1912 had poor tolerance to freezes based on its rank of 15 in CRS after it and 23 other genotypes were exposed to 93 h of temperatures ≤ −3°C between 10 Dec. 2010 and 27 Jan. 2011.
