Registration of ‘UFCP 82‐1655’ Sugarcane

Abstract

‘UFCP 82‐1655’ (Reg. No. CV‐164; PI 673050), a high fiber and low sucrose sugarcane, also called energy cane (a complex hybrid of Saccharum sp.), was developed through the collaborative effort of the University of Florida (UF) and the USDA‐ARS, Canal Point (CP) for its potential use in cellulosic ethanol production in Florida. UFCP 82‐1655 has moderate to high resistance against smut (caused by Sporisorium scitamineum). UFCP 82‐1655 did not have any natural infestation of brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by P. kuehnii), mosaic (caused by Sugarcane mosaic virus) and leaf scald [caused by Xanthomonas albilinenas (Ashby) Dawson]. Dry biomass yield (soluble plus insoluble dry weight) of UFCP 82‐1655 was not significantly different from ‘L 79‐1002’. Averaged across different crop cycles (plant cane, first ratoon, second ratoon, and third ratoon) at three locations in Florida (Citra, Tecan and Lykes Bros. farms), mean dry biomass yield of UFCP 82‐1655 was 32.7 Mg ha−1 compared with 30.6 Mg ha−1 for the reference check, L 79‐1002. Plant composition (% fiber) of UFCP 82‐1655 is composed of 41.7% cellulose, 27.9% hemicellulose, 22.6% lignin, 2.6% nonstructural ash, 2% structural ash, and 1.6% structural protein, which is quite similar to L 79‐1002. UFCP 82‐1655 is released to enhance genetic diversity and to improve disease resistance in energy cane.

“…Twenty simple sequence repeat (SSR) markers, spanning the 10 chromosomes of sugarcane (Cordeiro et al, 2000; Cordeiro and Henry, 2001; James et al, 2012; Parida et al, 2010; Singh et al, 2010), were used to molecularly genotype five selected lines (UFCP 74‐1010 [Sandhu et al, 2015b], UFCP 78‐1013 [Sandhu et al, 2015a], UFCP 82‐1655 [Sandhu et al, 2016], UFCP84‐1047, and UFCP 87‐0053) for which phenotypic data was collected from the field. Marker targets were amplified in the DNA using polymerase chain reaction (PCR).…”

“…L 79‐1002 has shown promising energy characteristics but has demonstrated an increasing susceptibility to smut disease (caused by Sporisorium scitamineum [Piepenbring et al, 2002]) in the field in Louisiana and Florida; thus, new high‐yielding and disease‐free germplasm was needed. In the past 5 yr, the USDA‐ARS Sugarcane Research Unit in Houma, LA, released three new energy cane cultivars—HoCP 91‐552 (Tew et al, 2011), Ho 00‐961 (White et al, 2011), and Ho 02‐113 (Hale et al, 2013)—for commercial production in Louisiana; and the USDA‐ARS Sugarcane Field Station in Canal Point, FL (in conjunction with the University of Florida) released the first five cultivars in Florida to expand the relatively narrow genetic base of energy cane (Sandhu et al, 2015a, 2015b, 2016) when compared to other crops. The energy cane cultivar UFCP 87‐0053 was included in this group of five cultivars for use on marginal soils in Florida.…”

“…Fifty‐three of the clones were planted in 5‐m single‐row plots, with three replications, on a Lauderhill muck soil (euic, hyperthermic Lithic Haplosaprists) at UF Everglades Research and Education Center in Belle Glade, FL (Dec. 2006). Five clones (‘UFCP 74‐1010’ [Sandhu et al, 2015b], ‘UFCP 78‐1013’ [Sandhu et al, 2015a], ‘UFCP 82‐1655’ [Sandhu et al, 2015c], UFCP 84‐1047, and UFCP 87‐0053 [Gordon et al, 2016) were selected from this group on the basis of disease resistances and biomass yield for commercial field‐testing at Tecan (26°37′84″ N, 80°56′19″ W; southern Florida), Citra (29°27′36″ N, 82°10′15″ W; northern Florida), and Lykes Bros. farms (27°12.2′ N, 81°5.28′ W; central Florida).…”
