Registration of 'CP 10-1716' sugarcane

'CP 10-1716' (Reg. no. CV-195, PI 691536) sugarcane (a complex hybrid of Saccharum spp.) was released (7 June 2018) through cooperative research by the USDA-ARS Sugarcane Field Station at Canal Point, the University of Florida, and the Florida Sugar Cane League, Inc. CP 10-1716 is recommended for use on mineral (sand) soils in Florida. CP 10-1716 resulted from polycross X07-1257 (CP 00-2180 x Mix07Q; male parent is unknown). Replicated trials at four sand soil locations, with yield data from 12 harvests and three crop cycles (i.e., plant cane, first ratoon, and second ratoon) showed that CP 10-1716 had cane and sugar yields, and profitability (economic index, US$ ha(-1)), that were similar to check cultivars ('CL 88-4730' and 'CP 96-1252'). Commercial recoverable sucrose (CRS) in CP 10-1716 was significantly lower than the check averages, but the early CRS was not significantly different from the mean of the checks. The economic index for CP 10-1716 vs. the mean of the checks was $2490 vs. $2445 ha(-1), respectively, with CP 10-1716 showing no significant difference from the mean of the checks. CP 10-1716 was rated as moderately resistant to ratoon stunt disease and resistant to brown and orange rust, mosaic, smut, leaf scald, and yellow leaf disease on sand soils. CP 10-1716 is positive for the Brul molecular marker that is one of the indicators for brown rust resistance. CP 10-1716 has low to moderate freeze tolerance as it relates to sucrose degradation.

Automated summary

CP 10-1716, a newly released sugarcane hybrid, exhibits similar cane and sugar yields as well as profitability on mineral soils in Florida compared to check cultivars. It shows moderate resistance to ratoon stunt disease and resistance to multiple diseases on sand soils, positive for a molecular marker related to brown rust resistance, and has low to moderate freeze tolerance.
