Interpretive Summary: New sugarcane cultivars that yield well on organic (muck) soils and/or sand soils and have acceptable resistance to major diseases are important in Florida for sugarcane sustainable production. Field data from three crops (plant cane and first- and second-ratoon crops) at multiple locations suggest CP 08-1110 yielded well in commercial sugarcane fields on sand soils. CP 08-1110 did not rank the top 13 in the Stage-3 yield tests on muck soils at three locations and thus it was not further tested in the Stage-4 trails on muck soils. On sand soils at three locations with three crops (plant cane, first ratoon, and second ratoon) and compared with CP 89-2143 and CL 88-4730 (two check cultivars for sand soils) in the final yield trails (Stage 4), CP 08-1110 had 19.0 and 36.6% higher cane yields, respectively and 14.1 and 40.9% higher sucrose yields. The three-year mean value of sugar content (commercial recoverable sucrose) of CP 08-1110 was 2.3% higher than that of CL 88-4730, but 4.0% lower than that of CP 89-2143 on sand soils. The economic index of CP 08-1110 was significantly (13.0% and 53.8%) higher than those of CP 89-2143 and CL 88-4730 on sand soils. Therefore, CP 08-1110 was released to growers as a new cultivar for sand soils only in Florida. CP 08-1110 has shown adequate resistance or tolerance to smut, leaf scald, brown rust, orange rust, sugarcane mosaic virus, and ratoon stunting for commercial production on sand soils, but is susceptible to sugarcane yellow leaf virus as are almost all sugarcane cultivars in Florida. CP 08-1110 may be poor in freeze tolerance compared with check cultivars.

Technical Abstract: ‘CP 08-1110’ (Reg. No.CV-171; PI 678579) 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 mineral (sand) soils in Florida in October 2014. CP 08-1110 was selected from a bi-parental cross made at Canal Point (CP), Florida on 20 Dec. 2006 with the CP sugarcane breeding lines of CP 01-2459 (female parent) and CP 00-2188 (male parent). CP 08-1110 was released by the Florida sugarcane variety committee because of its high cane and sucrose yields and acceptable commercial recoverable sucrose (CRS) on sand 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. xyli Evtsuhenko et al.), and smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.] in Florida. Based on results of nine harvests for three crops (plant cane, first ratoon, and second ratoon) in the final-stage replicated yield trials conducted at three locations on sand soils and compared with two reference cultivars CP 89-2143 and CL 88-4730, CP 08-1110 had 19.0 and 36.6% higher cane yield, and 14.1 and 40.9% higher sucrose yield respectively (P < 0.05). CP 08-1110 performed poor and ranked 16th (plant cane) to 19th (first ratoon) for freeze tolerance among 22 genotypes in field tests for temporal sucrose deterioration.
