Interpretive Summary: Energy cane is a relatively new generation of energy crops being bred as a source for biofuel feedstock and ethanol production. Current energy cane breeding strategies have focused on selecting high biomass hybrids from wide crosses between commercial sugarcane cultivars and S. spontaneum, which is characterized by high stalk counts and fiber content, excellent ratooning ability, and tolerances to abiotic and biotic pressures. A cooperative energy cane cultivar development program has been established between the USDA-ARS Sugarcane Field Station (Canal Point, Florida), the University of Florida-EREC (Belle Glade, Florida), and BP Biofuels North America, LLC (Houston, Texas) to produce high-yielding, and disease-resistant cultivars. As a result of four years of testing, energy cane cultivar UFCP74-1010 was developed in Florida and released this year. Yields of the new cultivar are comparable to, or exceed L79-1002 (released in 2008); but are not quite as robust as Ho02-113 (released in 2013). The UFCP74-1010 cultivar will provide a new source of energy cane.

Technical Abstract: UFCP 74-1010 (Reg. no. ) was released by the University of Florida (UF) and the United States Department of Agriculture – Agricultural Research Services (USDA-ARS), Canal Point (CP) for its potential use in cellulosic ethanol production. UFCP 74-1010, a cross between sugarcane varieties CP 66-56-4 and CL 47-83, is a high fiber sugarcane (Saccharum sp.), which has been released to enhance genetic diversity in a feedstock for cellulosic ethanol production in Florida. UFCP 74-1010 is moderately resistant to smut (caused by Sporisorium scitamineum) with significantly lower infestation compared to a reference check, L 79-1002, both under natural environmental conditions and artificial inoculations. UFCP 74-1010 is also resistant or moderately resistant, to several other sugarcane diseases including brown rust (caused by Puccinia melanocephala H. and P. Sydow), orange rust (caused by P. kuehnii), leaf scald [Xanthomonas albilinenas (Ashby) Dawson] and mosaic (caused by Sugarcane mosaic virus). Mean dry biomass yield of UFCP 74-1010 was approximately 11% higher than L 79-1002 averaged across eight location-years of field trials. Plant composition of UFCP 74-1010 is very similar to L 79-1002. UFCP 74-1010 is released to be cultivated for cellulosic ethanol production on marginal or sandy soils of Florida for cellulosic ethanol production.
