HoCP 91-552 is one of the energycane varieties being studied as part of the LSU AgCenter's Sustainable Bioproducts Initiative (SUBI). This energycane variety has fiber content about three to four percentage points higher than commercial sugarcane varieties along with comparable sucrose content. Researchers believe this variety could serve a dual purpose as a source for both raw sugar and fiber.

HoCP 91-552 is a product of the cross LCP 81-10 x CP 72-356 made at Canal Point (CP), Florida, in 1986 and selected at Houma (Ho), Louisiana, in 1988. This variety averaged 16% fiber in plant-cane and first-stubble in-field and outfield studies. HoCP 91-552 was examined in large-plot energycane tests conducted from 2004 to 2006 in which plant-cane, first-ratoon and second-ratoon crops were harvested with a combine harvester. The tests were planted at the USDA-ARS Sugarcane Research Laboratory’s Ardoyne Research Farm near Schriever, Louisiana, and at the Diamond W Ranch near Welch, Louisiana. In these tests, HoCP 91-552 produced 25% more soluble solids (Brix) and 34% greater total solids (Brix and fiber) than LCP 85-384 in combined plant-cane, first-ratoon and second-ratoon crops. This variety is resistant to sugarcane mosaic virus (strains A, B and D), sorghum mosaic virus (strains H, I and M), smut (Ustilago scitaminea Sydow), rust (Puccinia melanocephala H. and P. Syd.) and leaf scald [Xanthomonas albilineans (Ashby) Dowson] diseases. HoCP 91-552 is moderately resistant to the sugarcane borer (Diatraea saccharalis).
