Interpretive Summary: Sugarcane is grown on organic (muck) and sand soils in south Florida near Lake Okeechobee. This region produces approximately 20 % of the sugar consumed in the United States. New cultivars are developed for this region for both soil types; however, the process is more difficult for sand because of the more stressful conditions and field variation. Cultivar, CP 04-1566, was identified for sand soil with moderate resistance to brown and orange rusts, leaf scald, mosaic and smut with yields equal to the present commercial check, CP 78-1628, based on a three-crop meant. This will offer growers an alternative to the present cultivars for sand that have these disease concerns. CP 04-1566 is susceptible to yellow leaf caused by Sugarcane yellow leaf virus. Although not statistically significant CP 04-1566 had a higher economic index than the CP 78-1628. The main advantage of CP 04-1566 is its disease resistance.

Technical Abstract: CP 04-1566’ sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and was released to growers in Florida on 30 Sept. 2011. CP 04-1566 was selected from the cross X01-0246 (cultivars CP 89-2377 X CP 96-1252) made at Canal Point, FL on 29 Nov. 2001. Both parents were released for commercial production: CP 89-2377 for organic (muck) soils only and CP 96-1252 for both muck and sand soils. CP 04-1566 was tested in Stage 4 only on sand soils in Florida because of its superior yields on sand soils and substandard yields on organic soils in Stage 3. CP 04-1566 was released for sand soils because of its moderate resistant to all the major diseases in Florida: brown rust (caused by Puccinia melanocephala H. & P. Sydow) although it does not contain the Bru1 gene, a major brown rust resistance gene, orange rust (caused by Puccinia kuehnii E.J. Butler), and Sugarcane mosaic virus strain E (mosaic) and smut (caused by Ustilago scitaminea H. & P. Sydow), and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.) and is resistant to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), in Florida. CP 04-1566 has equal cane yield and commercial recoverable sucrose as the commercial check, CP 78-1628. CP 04-1566 is susceptible to Sugar Cane Yellow Leaf Virus. CP 04-1566 had moderate to poor tolerance to freezes based on its rank in CRS in two years evaluation in 2010-11 and 2011-12 at the University of Florida Hague Farm near Gainesville, Florida.
