Registration of 'CP 14-1934' sugarcane for Florida organic soils

'CP 14-1934' (Reg. no. CV-210, PI 700310) sugarcane cultivar, a complex hybrid of Saccharum spp., was developed through cooperative research of the USDA-ARS, the University of Florida, and the Florida Sugarcane League. The Florida Sugarcane Variety Committee released CP 14-1934 in June 2021 for commercial cultivation on organic (muck) soil. CP 14-1934 originates from a cross CPX11-1041 between CP 07-2460 (female parent) and CP 06-2335 (male parent). CP 14-1934 was released due to its high cane yield; high sucrose yields; acceptable commercial recoverable sucrose; and resistance to brown rust (tested positive to Bru1 marker), orange rust, sugarcane mosaic virus strain E (mosaic), and ratoon stunting disease. CP 14-1934 was found moderately resistant to leaf scald and to have intermediate freeze tolerance. Based on results of three harvests cycles over five locations in final-stage replicated yield trials (Stage 4) on muck soils, CP 14-1934 cane and sucrose yields were 17.8 and 19.8% greater than the mean of reference cultivars, respectively. CP 14-1934 rarely flowers in Florida's climate. The new released cultivar CP 14-1934 is expected to increase the profitability and the efficiency in the use of resources of Florida sugarcane growers.
