Narrative
Sugarcane (a complex hybrid of Saccharum spp.) cultivar ‘CP 11-1956’ was released in June 2018 for commercial cultivation on organic (muck) soils in Florida. This cultivar was developed through a collaborative cultivar development 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 combination of disease resistance against major sugarcane diseases and cane and sugar yields that are similar to check cultivars, that are major commercial cultivars in Florida. CP 11-1956 is considered resistant to brown rust, orange rust, ratoon stunting disease, smut, and mosaic. This cultivar is also moderately resistant to leaf scald, and yellow leaf disease. Cane and sucrose sugar yields of CP 11-1956 are similar to reference check cultivar, CP 96-1252 that has occupied the largest acreage in Florida for several years. CP 11-1956 had poor freeze tolerance compared with several commercial check cultivars. Agronomic and botanical descriptions of CP 11-1956 were compared with reference check, CP 96-1252 (Table 4). The comparisons between measurements such as stalk length and diameter are numerical. Stalks of CP 11-1956 were longer and had greater stalk diameter and internode length compared to CP 96-1252. Growth ring, root band, root primordia, buds and ligule were relatively wider in CP 11-1956 than CP 96-1252. Shape of internode, bud and ligule was similar in both cultivars. CP 11-1956 had one deltoid shaped auricle present while both auricles were absent in CP 96-1252. Stalks and buds were yellowish in both cultivars with a slight difference in tinge. Ligule color was red in CP 11-1956 and yellowish red in CP 96-1252.

Pedigree
Description:
CP 11-1956 was selected from a cross between CP 03-2188 as female parent and CP 01-2459 as male parent. Both parents were high yielding clones in the stage 4 test of the CP program in 2006-2009, but were not released for commercial production because of rust susceptibility.
