Abstract

Abstract: 'CP 14‐1490' (Reg. no. CV‐212, PI 700785), a sugarcane (a complex hybrid of Saccharum spp) cultivar, was developed through cooperative research conducted by the USDA‐ARS, the University of Florida, and the Florida Sugar Cane League, Inc. The Florida Sugarcane Variety Committee released CP 14‐1490 in June 2021 to growers for commercial cultivation on organic (muck) soils. It originated from a cross made at Canal Point (CP) on 29 Nov. 2011, where 'CP 04‐1844' (PI 664935) was the female parent, and the male parent was 'CPCL 02‐8021'. CP 14‐1490 was released for its high sugar yields; acceptable commercial recoverable sucrose (though it had significantly lower cane yield at the second ratoon); resistances to Sugarcane mosaic virus strain E (mosaic) and ratoon stunt disease (caused by Clavibacter xyli subsp. xyli Davis et al.); moderate resistances to brown [caused by Puccinia melanocephala (H. & P. Sydow)] and orange rusts [caused by Puccinia kuehnii (Kruger) E. Butler], and leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson]; and moderate susceptibility to smut [caused by Sporisorium scitamineum (Syd., M. Piepenbr., M. Stoll & Oberw)]. Yield data of CP 14‐1490 and reference checks (i.e., 'CP 00‐1101' [PI 651881], 'CP 96‐1252' [PI 634935], 'CPCL 05‐1201' [PI 672485]) were collected from 15 harvests (i.e., three crop cycles [plant cane, first and second ratoon] at five organic‐soil locations in final‐stage replicated yield trials. There was no significant difference in cane yield with all tested reference checks and no significant difference in sugar yield with CP 00‐1101 and CPCL 05‐1201. When compared to CP 96‐1252, CP 14‐1490 had significantly ( P ≤ .05) higher sucrose yield (19.2%) and commercial recoverable sucrose (5%). CP 14‐1490 rated moderately tolerant to freezing among 23 tested genotypes. Core Ideas: 'CP 14‐1490' sugarcane was released for cultivation in organic (muck) soil in Florida. 'CP 14‐1490' has high sucrose yield potential compared with commercial cultivar 'CP 96‐1252'. 'CP 14‐1490' is resistant or partially resistant to economically important sugarcane diseases and had intermediate tolerance to freeze.
