Interpretive Summary: Continuous improvement of cultivars is necessary to support sustainable crop growth and sugarcane production in US agriculture. The Florida sugarcane variety committee released a new cultivar, CP 15-1407, because of its heavier stalks and equivalent economic success on Florida's organic (muck) soils. It has modest resistance to yellow leaf syndrome and is resistant to brown rust, orange rust, sugarcane mosaic virus, leaf scald, smut, and ratoon stunt diseases. In late-stage replicated yield trials on sand soils, 15 harvests were conducted at five different locations, and the findings showed that stalks of CP 15-1407 were heavier than the best check cultivar, CP 96-1252, by a margin of 27.8%. Additionally, this novel cultivar produced cane yield and economic return that was comparable to the performance of the commercial cultivars CP 96-1252. It also displayed superior resistance to brown and orange rust diseases. With its demonstrated resistance to disease and comparable cane production capacity, CP 15-1407 is expected to positively influence both sugarcane production and crop sustainability in Florida.

Technical Abstract: The complex hybrid sugarcane (Saccharum spp.) cultivar ‘CP 15-1407’ (Reg. no. CV-217; PI 704105) was made available to growers in June 2022 for cultivation on muck soils in Florida. This development took 10 years thanks to collaborative research by the USDA–ARS, the Florida Sugar Cane League Inc., and the University of Florida. It started at Canal Point (CP) as a bi-parental cross between ‘CP 08-1110’ (female) and CP 05-1616 (male). Due to its high stalk weight, adequate disease resistance, higher recoverable sugar, and equivalent cane yield to best check ‘CP 96-1252’ on muck soils, the Florida Sugarcane Variety Committee recommended releasing CP 15-1407. It has demonstrated resistance to brown rust, orange rust, sugarcane mosaic, smut, leaf scald, and ratoon stunt and is moderately susceptible to yellow leaf. In latestage, on-farm yield trials, CP 15-1407 stalk weights were 27.8% heavier than that of CP 96-1252, while cane yields and economic index (EI) did not differ from CP 96- 1252. Florida sugarcane output and crop sustainability are predicted to benefit from CP 15-1407’s sustained cane production capacity and proven disease resistance.
