1. SUMMARY
The ‘CP 08-1110’ sugarcane cultivar (PI 678579; Saccharum spp. hybrid) was developed with much higher cane and sucrose yields, and acceptable commercial recoverable sucrose than current commercial check cultivars (‘CP 89-2143’ and ‘CL 88-4730’) on mineral (sand) soils in Florida. It also has tolerance and acceptable levels of resistance to multiple diseases: 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, ratoon stunt (caused by Leifsonia xyli subsp. xyli, Evtsuhenko et al.), and smut (caused by Sporisorium scitamineum (Syd.), M. Piepenbring et al.).
The goal was to develop high-yielding cultivars with enhanced resistance or tolerance to biotic and abiotic stresses for muck and sandy soils in Florida.

2. PROBLEMS ADDRESSED
Poor cane and sucrose yield and acceptable commercial recoverable sucrose of commercial cultivars on sandy soils and disease susceptibility in Florida contributed to cane yield reduction of 18.5% to 24.9% and sucrose yield reduction of around 30%.
3. SOLUTIONS DEVELOPED
‘CP 08-1110’ was derived from a long-term recurrent selection program and was selected from a biparental cross (‘CP 01-2459’ x ‘CP 00-2188’) using standard selection procedures (Zhao et al., 2017). It is a complex hybrid (arising from a total of 21 individual genetic sources) with a pedigree tracing back to great-great-grand-parents (a wild material, ‘IND 81-1446’ – PI 504789 and cultivar ‘Green German’ – PI 68052, five successful commercial cultivars – ‘CP 52-68’, which was released for commercial production in Louisiana (Heinz and Tew, 1987), ‘CP 70-1133’ (Rice et al., 1978), ‘CP 72-1210’ (Miller et al., 1981), ‘CP 72-2086’ (Miller et al., 1984), and ‘CP 74-2005’ (Tai et al., 1984) ), an introduced cultivar ‘R 567’ from Reunion, and the wide cross ‘US 94-1054’. Of these ancestral cultivars, CP 70-1133 and CP 72-2086 were the most widely grown sugarcane cultivars in Florida from 1982 to 1994 (Donovan and Glaz, 1985; Glaz, 1995). ‘CP 08-1110’ stands for the 110th (recorded 1110) selection assigned in the year 2008 (08) in the first clonal selection stage; CP refers to Canal Point.
