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 UFCP82-1655 was developed in Florida and released this year. Yields of the new cultivar exceeded L79-1002 (released in 2008). The UFCP82-1655 cultivar will provide a new source of energy cane. Technical

Technical Abstract: UFCP 82-1655’ (Reg. no. ), a high fiber and low sucrose sugarcane (a complex hybrid of Saccharum sp.) was developed through the collaborative effort of 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 in Florida. Because of its use in energy production, it is also called energy cane. UFCP 82-1655 was released publically on 30 September 2013 for its potential cultivation on marginal or sandy soils of Florida. UFCP 82-1655 has high biomass and moderate to high resistance against smut (caused by Sporisorium scitamineum), the most important energy cane disease in Florida. Averaged across different crop cycles (plant cane, first ratoon, second ratoon, and third ratoon) at three locations (Citra, Tecan and Lykes Brothers Farm) in Florida, mean dry biomass yield of UFCP 82-1655 was approximately 9.7% greater than the reference check, L 79-1002. UFCP 82-1655 didn’t have any natural infestation of brown rust (caused by Puccinia melanocephala H. and P. Sydow), orange rust (caused by P. kuehnii), mosaic (caused by Sugarcane mosaic virus) and leaf scald [Xanthomonas albilinenas (Ashby) Dawson]. Plant composition (% fiber) of UFCP 82-1655 comprised of 41.7% cellulose, 27.9% hemicellulose, 22.6% lignin, 2.6% non-structural ash, 2% structural ash, and 1.6% structural protein, which was very similar to L 79-1002. UFCP 82-1655 is released to enhance genetic diversity and to improve disease resistance in energy cane.
