Interpretive Summary: New sugarcane varieties are necessary for continued high yields in Louisiana because of adverse conditions such as freezing cold and disease and insect pests. The variety development program at the USDA-ARS Sugarcane Research Station in Houma Louisiana makes crosses with favorable clones and evaluates their progeny in 20 locations in a process that takes over 11 years from cross to release. One of these, the released variety HoCP 04-838, is cold tolerant and resists disease. Cold, disease and insect pests, damage sugarcane and lowers the sugar yield, which is a financial loss to farmers. This variety HoCP 04-838 has cold tolerance, disease and insect resistance which have the potential to increase agricultural production and profits in Louisiana.

Technical Abstract: ‘HoCP 04-838’ sugarcane (an interspecific hybrid of S. officinarum, S. barberi Jeswiet, S. spontaneum, and S. sinense Roxb. amend. Jeswiet) was selected and evaluated by scientists at the USDA-ARS, working cooperatively with the Louisiana State University Agricultural Center, and the American Sugar Cane League, Inc. It was released to growers in Louisiana in May 2011. Yields from three crops (plant, first- and second-ratoon) at 12 farm locations compared well with HoCP 96-540, the most widely grown variety in Louisiana during that time. The plant-cane sucrose yield (Mg ha-1) of HoCP 04-838 was equivalent to HoCP 96-540, and cane yield was significantly higher than HoCP 96-540. HoCP 04-838 is earlier maturing than HoCP 96-540 but not as early as HoCP 00-950 the high sucrose standard variety. Mature stalk cold tolerance was similar to LCP 85-384 the cold tolerance standard. HoCP 04-838 is resistant to smut (Sporisorium scitamineum), mosaic caused by Sorghum mosaic virus, brown rust (Puccinia melanocephala) and ratoon stunt (Leifsonia xyli). HoCP 04-838 is moderately resistant to leaf scald (Xanthomonas albilineans) and is susceptible to sugarcane yellow leaf virus. It is resistant to sugarcane borer, Diatraea saccharalis F. HoCP 04-838’s high yield potential and cold tolerance make it a useful addition to existing commercial sugarcane varieties in Louisiana.
