‘HoCP 04‐838’ (Reg. No. CV‐181, PI 687221) sugarcane (interspecific hybrids of Saccharum spp.) was selected and evaluated by scientists at the USDA–ARS, working cooperatively with the Louisiana State University Agricultural Center, and the American Sugarcane League, Inc., from a cross between the female parent ‘HoCP 85‐845’ and the male parent ‘LCP 85‐384’. It was released to growers in Louisiana in May 2011. Yields from three crops (plant, first ratoon, and second ratoon) at 12 farm locations compared well with HoCP 96‐540, the most widely grown cultivar 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 cultivar. Mature stalk cold tolerance was similar to LCP 85‐384, the cold tolerance standard. HoCP 04‐838 is resistant to smut, mosaic caused by Sorghum mosaic virus, brown rust, and ratoon stunt. HoCP 04‐838 is moderately resistant to leaf scald and is susceptible to Sugarcane yellow leaf virus. It is resistant to sugarcane borer. HoCP 04‐838's high yield potential and cold tolerance make it a useful addition to existing commercial sugarcane cultivars in Louisiana.
