Interpretive Summary: Three improved sugarcane cultivars of ‘CP 09-4153’, ‘CPCL 09-4160’, and ‘CP 09-4758’ were released by the Florida Sugarcane Variety Committee in June 2016 for commercial use on sand soils in Florida. Averaged across plant cane, first ratoon, and second ratoon and compared to CL 88-4730 (a commercial reference cultivar), CP 09-4153 and CP 09-4758 had 32.4 and 21.9% higher cane yields, and 28.1 and 20.2% higher sucrose yields, respectively. CPCL 09-4160 did not differ from CL 88-4730 in either cane or sucrose yield, but demonstrated resistance to most diseases. CP 09-4153 and CP 09-4758 had low-moderate freeze tolerances, while CPCL 09-4160 was moderately tolerant under the same conditions. It is expected that CP 09-4153, CPCL 09-4160, and CP 09-4758 will help growers improve sugarcane production and profits on the Florida sand soils.
Technical Abstract: ‘CP 09-4153’ (Reg. No. ____; PI ___), ‘CPCL 09-4160’ (Reg. No. ____; PI ___), and ‘CP 09-4758’ (Reg. No. ____; PI ___) sugarcane (a complex hybrid of Saccharum spp.) were released in June 2016 to be cultivated on mineral (sand) soils in Florida. These three sugarcane cultivars were developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. Female and male parents are: CPCL 97-0393 and CPCL 02-8021 for CP 09-4153; CP 80-1743 and Poly 01-8 (i.e. multiple potential pollen donors) for CPCL 09-4160; and CP 97-2103 and CP 92-1167 for CP 09-4758. Averaged across three crop cycles, CP 09-4153 and CP 09-4758 had 32.4 and 21.9% higher cane yield and 28.1 and 20.2% higher sucrose yield compared to CL 88-4730, a commercial reference cultivar. CPCL 09-4160 did not differ significantly from CL 88-4730 in cane and sucrose yield but was resistant to all major sugarcane diseases in the region except brown rust (moderately resistant) and ratoon stunt (moderately susceptible). CP 09-4153 and CP 09-4758 were considered low to moderate in freeze tolerance while CPCL 09-4160 was considered moderate in freeze tolerance Overall, these three cultivars were released by the Florida sugarcane variety committee due to their high cane and sucrose yields particularly in the ratoon crops and acceptable levels of resistance to brown rust, orange rust except CP 09-4758, smut, leaf scald except CP 09-4758, Sugarcane mosaic virus strain E, ratoon stunt except CPCL 09-4160, and Sugarcane yellow leaf virus.
