Narrative
The mean stalk height (ground level to top visible dewlap, dewlaps form the hinge of the blade joint in sugarcane) of 10 CP 08-1968 stalks was 296 cm. The mean internode length of 10 CP 08-1968 stalks at the fifth internode from the ground was 14.8 cm. Stalk diameter was measured at the middle of the second (26.5 mm), fifth (25.3 mm), and tenth (22.1 mm) internodes from the ground as well as at the middle of the hardened internode closest to the top visible dewlap (21.3 mm). CP 08-1968 exhibited a cylindrical shaped internode and a growth ring with a mean width of 2.9 mm at the fifth internode from the ground. The root band of CP 08-1968 was 7.2 mm wide. Bud furrows were mostly absent. The buds of CP 08-1968 were yellow (5Y8/4 to 2.5Y8/6). Buds of CP 08-1968 were moderately raised above the surface of the root band and had shapes described as narrow ovate bud with wing boarding towards apex at the fifth internode from the ground. The bud length and width means of the fifth bud from the bottom from five stalks of CP 08-1968 were 7.5 and 6.5 mm, respectively. Leaf sheath pubescence was absent for CP 08-1968. The buds of CP 08-1968 had no pubescence. CP 08-1968 is resistant to Sugarcane mosaic virus strain E (mosaic), moderately resistant to brown rust (caused by Puccinia melanocephala H. & P. Sydow), smut (caused by Sporisorium scitamineaum (Syd.) M Piepenbr., M. Stoll & Oberw.), and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.). It is moderately susceptible to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson) and orange rust (caused by Puccinia kuehnii E.J. Butler). In addition, CP 08-1968 tested negative for the presence of the Bru1 gene which confers resistance to brown rust.

Pedigree
Description:
Parents of CP 08-1968 were the two CP sugarcane breeding lines CP 01-1178 (female) and CP 00-1301 (male). Grandparents on the female side were CP 84-1198 and CP 82-1172, and on the male side were CP 75-1632 and CP 89-2143. Known great grandparents on the female side were CP 70-1133, CP 72-2086, CP 75-1091, and CP 75-1283 and on the male side were CP 68-1067, CP 70-1133, CP 72-2086, and CP 81-1254. Of the grandparents and great grandparents, there were five successful commercial sugarcane cultivars (CP 70-1133, CP 72-2086, CP 81-1254, CP 84-1198, and CP 89-2143) in Florida. Known great-great grandparents were CP 52-68, CP 57-603, CP 57-614, CP 62-374, CP 63-588, CP 68-1026, CP 68-1067, CP 70-1133, CP 70-1233, and CP 72-1210. There were seven commercial cultivars among its great-great grandparents: CP 52-68 that was released for commercial production in Louisiana, CP 56-63, CP 57-603, CP 62-374, CP 63-588, CP 70-1133, and CP 72-1210 in Florida. Of these ancestral cultivars, CP 63-588, CP 70-1133 and CP 72-1210 were the most widely grown sugarcane cultivars in Florida from 1980 to 1991.
