Registration of ‘HoCP 85‐845’ Sugarcane

Self Cite

HoCP 04-838' (Reg. No. CV-181, PI 687221) sugarcane (interspeciic 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, irst 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 signiicantly 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.

“…Both the leaf blade and midrib of L 01–283 were linear, glabrous with smooth surfaces, and relatively thin. The dewlaps of L 01–283 were squarish deltoid, and their colors were brownish but not as dark as the dewlaps of HoCP 85–845 (Legendre et al, 1994). L 01–283 exhibited a slight, necrotic leaf sheath margin.…”

“…For the plant‐cane crop, L 01–283 was not significantly different from any cultivar in sugar yield, cane yield, and sucrose content except that ‘HoCP 91–555’ (Legendre et al, 2000) had higher sucrose content. L 01–283 had a higher sugar yield, cane yield, and sucrose content in the first ratoon crop than ‘HoCP 85–845’ (Legendre et al, 1994). The trend was similar in the second ratoon crop except LCP 85–384 and HoCP 85–845 had a lower sugar yield and sucrose content.…”

‘L 01–283’ (Reg. No. CV‐140, PI 658001) sugarcane (a complex hybrid of Saccharum officinarum L., S. barberi Jeswiet, S. spontaneum L., and S. sinense Roxb. amend. Jeswiet) was released on 6 May 2008 by the Louisiana State University Agricultural Center in cooperation with the USDA‐ARS and the American Sugarcane League, Inc. L 01–283 was released because of its high sugar and cane yields, early maturity, and excellent ratooning ability. Cumulative data indicated that L 01–283 produced 10% higher sugar yield, 5% higher cane yield and 4% higher sucrose content than ‘HoCP 96–540’ when averaged across all crops. The new cultivar is moderately resistant to common brown rust disease (caused by Puccinia melanocephala Syd. & P. Syd.), resistant to smut disease (caused by Ustilago scitaminea Syd. & P. Syd.), resistant to leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson], resistant to mosaic strains, and moderately resistant to the sugarcane borer (Diatraea saccharalis F.). The cross for L 01–283 (XL96–402) was made on 22 October 1996. Early stage clonal selection was done as single stools in 1998 followed by the first clonal line trial selection in 1999 and the second clonal line trial selection in 2000. Testing in replicated yield trials was conducted throughout the sugarcane growing area in south Louisiana from 2002 to 2008.

“…Fifty‐one mechanically harvested outfield trials were conducted across 10 south Louisiana locations from 2001 through 2003. The commercial sugarcane cultivars included for comparison were LCP 85‐384, HoCP 85‐845 (Legendre et al, 1994), HoCP 91‐555 (Legendre et al, 2000), and HoCP 96‐540 (Tew et al, 2005). A 15‐stalk sample was collected before harvest to determine stalk weight and for a sucrose analysis.…”

‘L 97‐128’ (Reg. No. CV‐129, PI 650858) sugarcane (a complex hybrid of Saccharum officinarum L., S. barberi Jeswiet, S. spontaneum L., and S. sinense Roxb. amend. Jeswiet) was released on 5 May 2004 by the Louisiana State University Agricultural Center in cooperation with the USDA‐ARS and the American Sugarcane League, Inc. L 97‐128 has early high sucrose content, high cane yield potential, and resistance to common brown rust disease (Puccinia melanocephala H. and P. Syd.). Both the cross and the early stage clonal selection were made at Louisiana State University Agricultural Center's Sugar Research Station, St. Gabriel; permanent cultivar assignment was done in 1997. The cross was made on 25 Sept. 1992. Early stage clonal selection was done as single stools in 1994 followed by first clonal line trial selection in 1995 and second clonal line trial stage selection in 1996. Testing in replicated yield trials was conducted through the sugarcane growing area in south Louisiana from 1998 through 2003. Plant patent 17,636 was issued on 24 Apr. 2007.
