Interpretive Summary: CP 16-2283 sugarcane cultivar was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CP 16-2283 was released to the Florida growers for cultivation on muck soils for its high sucrose yield and resistance to economically important sugarcane diseases. CP 16-2283 had 6.3 % higher sucrose yield than check cultivar CP 96-1252 on muck soils across multiple field trials, had similar cane yield to CP 96-1252, and better ratooning ability than CP 96-1252. Its resistance or tolerance to most major sugarcane diseases may help in cutting the cost of fungicide application, which would improve profitability.

Technical Abstract: CP 16-2283 (Reg.no., PI 706648) sugarcane cultivar (a complex hybrid of Saccharum spp.) was released to growers for commercial cultivation on organic (muck) soils in July 2024. It was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. It originated from a biparental cross made at Canal Point (CP), Florida, on 30 December 2013 where CP 06-2897 was the female parent, and the male parent was ‘CP 06-2400’ [PI 670018]. CP 16-2283 has higher commercial recoverable sucrose, sucrose content, and ratooning ability than CP 96-1252, but similar cane yield to CP 96-1252. CP 16-2283 is resistant to brown rust, orange rust, sugarcane mosaic virus strain E (mosaic), and smut, with moderate resistance to leaf scald and ratoon stunt disease. CP 16-2283 possesses the positive allele for the Bru1 marker, which is linked to brown rust resistance. Yield data of CP 16-2283 and commercial reference cultivars (‘CP 00-1101’ [PI 651881] and ‘CP 96-1252’ [PI 634935]) were collected from 15 harvests i.e. three crop cycles (plant cane, first and second ratoon) at five organic-soil locations in final-stage replicated yield trials. When compared to CP 96-1252, CP 16-2283 had significantly (P < 0.05) higher commercial recoverable sucrose (6.3%) at all crop cycles. The sucrose content of CP 16-2283 was statistically equivalent to that of CP 00-1101, a high-sugar check cultivar with relatively low yield. CP 16-2283 was released for commercial production for its equivalent cane yield and improved CRS, sucrose content, disease resistance, and ratooning ability compared to the commonly-cultivated check CP 96-1252. CP 16-2283 was moderately tolerant to freeze among 23 tested genotypes. With its demonstrated resistance to diseases, and higher sucrose content than CP 96-1252, CP 16-2283 is expected to positively influence the profitability of sugarcane production in Florida’s organic soils.
