Registration of ‘UFCP 78-1013’ Sugarcane Cultivar

Abstract

Sugarcane (a complex hybrid of Saccharum sp.) cultivar UFCP 78‐1013 (Reg. No. CV‐162; PI 673049) was developed through the collaborative efforts of the University of Florida (UF) and the USDA‐ARS, Canal Point (CP), and released for its potential use in cellulosic ethanol production in Florida. Biomass is the most favorable characteristic of a potential feedstock for cellulosic ethanol production and must be improved in cultivars adapted to Florida conditions should cellulosic ethanol prove feasible for energy production. Averaged across eight location‐years of field trials, mean dry biomass yield of UFCP 78‐1013 was numerically greater than the reference check, ‘L 79‐1002’. Plant composition of UFCP 78‐1013 is similar to L 79‐1002. The parents for UFCP 78‐1013 are the sugarcane cultivar CP 68‐1067 (female parent) and S. spontaneum line SES 602 (male parent). UFCP 78‐1013 has moderate to high resistance against smut (caused by Sporisorium scitamineum) with significantly lower infestation than L 79‐1002, under both natural environmental conditions and artificial inoculation. UFCP 78‐1013 did not have symptoms of brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by P. kuehnii), mosaic (caused by Sugarcane mosaic virus) or leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson] during field evaluations. UFCP 78‐1013 is adapted to marginal or sandy soils of Florida.

“…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).…”
