Interpretive Summary: Sugarcane cultivar ‘CP 11-1956’ was released in 2018 for its commercial cultivation on muck soils in Florida. This cultivar was developed through a collaborative breeding and selection program of the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, based at Canal Point, Florida. The female parent of CP 11-1956 is CP 03-2188 and its male parent is CP 01-2459. CP 11-1956 was released because of its excellent package of disease resistance against major sugarcane diseases and acceptable yields which are similar to top commercial cultivars in Florida. CP 11-1956 is considered resistant to brown rust, orange rust, smut, and mosaic. CP 11-1956 is also moderately resistant to leaf scald, ratoon stunting disease, and yellow leaf disease. Cane and sucrose yields of CP 11-1956 are similar to reference cultivar, CP 96-1252 that is occupying the largest acreage in Florida for seve years. CP 11-1956 had poor Freeze tolerance compared with several commercial check cultivars.

Technical Abstract: Sugarcane (a complex hybrid of Saccharum spp.) cultivar ‘CP 11-1956’ (Reg. no. CV-198; PI 695075) was released in June 2018 for its commercial cultivation on organic (muck) soils in Florida. This cultivar was developed through a collaborative breeding and selection program of the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, based at Canal Point, Florida. The parents of CP 11-1956 are CP 03-2188 (female) and CP 01-2459 (male). CP 11-1956 was released because of its excellent package of disease resistance against major sugarcane diseases and acceptable yields which are similar to top commercial cultivars in Florida. CP 11-1956 is considered resistant to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.], and mosaic (caused by Sugarcane mosaic virus Stain E). This cultivar is also moderately resistant to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), ratoon stunting disease (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.) and yellow leaf disease (caused by Sugarcane yellow leaf virus). Cane and sucrose yields of CP 11-1956 are similar to reference cultivar, CP 96-1252 that is occupying the largest acreage in Florida for several years. CP 11-1956 had poor Freeze tolerance compared with several commercial check cultivars.
