Registration of ‘L 01–299’ Sugarcane

Abstract

‘L 01–299’ (Reg. No. CV‐141, PI 659071) sugarcane (a complex hybrid of Saccharum officinarum L., S. barberi Jeswiet, S. spontaneum L., and S. sinense Roxb. amend. Jeswiet) was released on 28 Aug. 2009 by the Louisiana State University Agricultural Center in cooperation with the USDA‐ARS and the American Sugarcane League, Inc. L 01–299 was released because of its high sugar and cane yields, erectness, and excellent ratooning ability. The cross for L 01–299 (XL96–402) was made on 22 Oct. 1996. Early‐stage clonal selection was done as single stools in 1998 followed by selection in the first clonal line trials in 1999, selection in the second clonal line trials in 2000, and permanent cultivar assignment in 2001. Testing in replicated yield trials was conducted throughout the sugarcane‐growing area in south Louisiana from 2002 to 2008. Cumulative data indicated that L 01–299 had a 14% higher sugar yield, 13% higher cane yield, and 1% higher sucrose content than ‘HoCP 96–540’ when averaged across all crops. The new cultivar is resistant to common brown rust disease (caused by Puccinia melanocephala Syd. & P. Syd.), susceptible to smut disease (caused by Ustilago scitaminea Syd. & P. Syd.), moderately resistant to leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson], resistant to mosaic strains, and moderately resistant to the sugarcane borer (Diatraea saccharalis F.).

Registration of ‘L 03‐371’ Sugarcane

“…Thus, we have 3 yr of plant‐cane data, 2 yr of first‐ratoon data, and 1 yr of second‐ratoon data for L 03‐371. In the plant‐cane crop, the new cultivar, L 03‐371, had a significantly higher sugar yield than the commercial cultivars LCP 85‐384, Ho 95‐988 (Tew et al, 2005a), HoCP 96‐540, L 97‐128 (Gravois et al, 2008), and L 01‐299 (Gravois et al, 2011); its sugar yield was similar to that of the other cultivars. In the first‐ratoon crop, the sugar yield of L 03‐371 was significantly less than that of L 01‐299 and significantly greater than the sugar yields of LCP 85‐384, Ho 95‐988, and L 97‐128.…”

Effect of Synthetic Auxin Herbicides Applied During Sugarcane Grand Growth on Starch Accumulation and Color

“…Greater sucrose yield was attributed to 28-37% more cane yield than HoCP 96-540 and HoCP 04-838, and was likely due to more millable stalks in the first and second-ratoon crop (Table 2). Gravois et al (2011) reported L 01-299 stalk population increased 18% from plant cane to first ratoon, 6% from first to second ratoon, and 1% from second to third ratoon when averaged across ten locations; however, the HoCP 96-540 stalk population decreased 1 and 25% from plant cane to first ratoon and from second to third ratoon, respectively.…”

Sugarcane cultivar response to glyphosate and trinexapac-ethyl ripeners in Louisiana

“…The experimental design was a split-plot factorial arrangement of ripener treatments and cultivars with four replications. Whole-plots were ripener treatment with three levels and subplots were nine sugarcane cultivars HoCP 96–540 [9], L 99–226 [10], HoCP 00–950 [11], L 01–283 [12], L 01–299 [13], HoCP 04–838 [14], Ho 07–613, Ho 09–804 [15], and HoCP 09–840 that were randomly allocated to subplots within each whole plot. Glyphosate (Roundup WeatherMax, Monsanto, St. Louis, MO) and trinexapac-ethyl (Moddus, Syngenta Crop Protection, Greensboro, NC) were applied at a rate of 210 g ae ha -1 and 200 g ai ha -1 , respectively.…”
