Registration of ‘UFCP 74-1010’ Sugarcane

Abstract

Sugarcane 'UFCP 74-1010' (Reg. No. CV-160, PI 673048) was released by the University of Florida and the USDA-ARS, Canal Point, for its potential use in cellulosic ethanol production. UFCP 74-1010, a cross between sugarcane (a complex hybrid of Saccharum spp.) cultivars CP 66-56-4 and CL 47-83. UFCP 74-1010 is a high iber sugarcane that has been released to improve biomass production for cellulosic ethanol production in Florida. UFCP 74-1010 is moderately resistant to smut (caused by Sporisorium scitamineum) with signiicantly lower infestation compared with a reference check, 'L 79-1002', under both natural environmental conditions and artiicial inoculations. UFCP 74-1010 is also resistant to brown rust (caused by Puccinia melanocephala H. and P. Sydow), orange rust (caused by P. kuehnii), and mosaic (caused by Sugarcane mosaic virus) and is moderately resistant to leaf scald [Xanthomonas albilineans (Ashby) Dawson]. Mean dry biomass yield of UFCP 74-1010 (29.2 Mg ha −1 ) was approximately 5% higher than L 79-1002 (27.9 Mg ha −1 ), averaged across eight location-years of ield trials. Plant composition of UFCP 74-1010 is similar to L 79-1002 with 41.9% cellulose, 27.8% hemicellulose, 22.4% lignin, 5.0% ash, and 1.6% structural protein. UFCP 74-1010 is released to be cultivated

Registration of ‘UFCP 87‐0053’ Sugarcane for Use as a Biofuel Feedstock

“…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.…”

Registration of ‘UFCP 84‐1047’ Sugarcane for Use as a Biofuel Feedstock

“…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).…”

Registration of ‘UFCP 82‐1655’ Sugarcane

“…The SSRs used to fingerprint UFCP 82‐1655 were also used to characterize the genotypic differences of four other cultivars released at the same time (UFCP 74‐1010 [Sandhu et al, 2015], UFCP 78‐1013, UFCP 84‐1047, and UFCP 87‐0053). The SSRs used for this purpose originated from a large pool of molecular probes being used to genotype sorghum for disease resistances and were selected based on both their distribution across all 10 sorghum chromosomes and their high polymorphic information content scores in the sorghum genome.…”
