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 newly released variety HoCP 09-804, regrows as well as the current top producer but is earlier maturing. Good regrowth benefits farmers by saving them money on replanting and early maturity is important allowing farmers to make money on sugar if harvested early. This variety also showed good cold tolerance and showed less deterioration when frozen protecting the farmer’s investment in inclement weather. This variety HoCP 09-804 has high yield, regrowth ability and cold tolerance which have the potential to increase agricultural production and profits in Louisiana.

Technical Abstract: ‘HoCP 09-804’ (Reg. No. CV-xxx, PI xxxxxx) sugarcane (a complex hybrid of S. officinarum, S. barberi Jeswiet, S. spontaneum, and S. sinense Roxb. amend. Jeswiet) was selected and evaluated by the USDA-ARS, working cooperatively with the Louisiana State University AgCenter, and the American Sugar Cane League, Inc. HoCP 09-804 was selected from a biparental cross between ‘HoCP 02-625’ and ‘HoCP 01-523’ made at the USDA-ARS, Sugarcane Field Station, Canal Point, FL in 2004, and released to growers in Louisiana in 2016 because of high cane and sucrose yields. Yields from 3 crops (plant, first and second ratoon) at 12 outfield locations compared well with the L 01-299, the highest yielding variety currently being grown in Louisiana. The plant-cane sugar yield (Mg ha-1) of HoCP 09-804 was significantly greater than HoCP 96-540, L 01-283 and L 01-299. The sucrose content (kg Mg1) was second only to HoCP 00-950, the industry standard for high sucrose, in all three crops. It was among the earliest maturing varieties ranking second only to HoCP 00-950, and was among the most cold tolerant similar to HoCP 04-838. HoCP 09-804 is mildly susceptible to smut (Sporisorium scitamineum), leaf scald (Xanthomonas albilineans), and ratoon stunt (Leifsonia xyli). HoCP 09-804 is susceptible to brown rust (Puccinia melanocephala), and mosaic caused by Sorghum mosaic virus. It is moderately susceptible to sugarcane borer, Diatraea saccharalis F. This variety’s high yield potential, ratooning ability and cold tolerance make it a useful addition to existing sugarcane varieties in Louisiana.
