Registration of ‘CP 06-2425’, ‘CP 06-2495’, ‘CP 06-2964’, ‘CP 06-3103’, and ‘CP 07-1313’ sugarcane for sand soils in Florida. Journal of Plant Registrations. 11:143-151. Interpretive Summary: Sugarcane yield improvement and sustainable production on sand soils in Florida are challenging. ‘CP 06-2425’, ‘CP 06-2495’, ‘CP 06-2964’, ‘CP 06-3103’, and ‘CP 07-1313’ sugarcane were released in June 2015 by the Florida sugarcane variety committee to be cultivated on sand soils in Florida. These five cultivars were developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. Averaged across three crops (plant cane, first ratoon, and second ratoon) on the Townsite sand soil, CP 06-2425, CP 06-2495, CP 06-2964, CP 06-3103, and CP 07-1313 had 22.4, 32.7, 18.0, 23.4, and 23.7% higher cane yield than CL 88-4730, a commercial reference cultivar. All cultivars except CP 06-2425 had higher sucrose yield compared to CL 88-4730. These cultivars were released due to their high cane and sucrose yields particularly in the ratoon crops and acceptable level of resistance to brown and orange rusts except for CP 06-2425, smut, leaf scald, Sugarcane mosaic virus strain E (mosaic), and ratoon stunt. It is expected that these five cultivars will help growers improve sugarcane yields and profits on sand soils in Florida. Technical Abstract: ‘CP 06-2425’ (Reg. No. CV-172; PI 678574), ‘CP 06-2495’ (Reg. No. CV-173; PI 678575), ‘CP 06-2964’ (Reg. No. CV-174; PI 678576), ‘CP 06-3103’ (Reg. No. CV-175; PI 678577), and ‘CP 07-1313’ (Reg. No. CV-176; PI 678578) sugarcane (a complex hybrid of Saccharum spp.) were released in June 2015 to be cultivated on mineral (sand) soils in Florida. These five 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: CP 01-1625 and 03 P 29 for CP 06-2425; CP 94-2095 and CP 97-1387 for CP 06-2964; TCP 00-4519 and CP 84-1198 for CP 07-1313; and unknown for both CP 06-2495 and CP 06-3103. Averaged across three crop cycles, CP 06-2425, CP 06-2495, CP 06-2964, CP 06-3103, and CP 07-1313 had 22.4, 32.7, 18.0, 23.4, and 23.7% higher cane yield than CL 88-4730, a commercial reference cultivar. These cultivars were released by the Florida sugarcane variety committee due to their higher cane and sucrose yields particularly in the ratoon crops and acceptable level of resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler) except for CP 06-2425, smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.], leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E (mosaic), and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.). |
