* R = resistant enough for commercial production; L = low levels of disease susceptibility; S = too susceptible for production; U = undetermined susceptibility (available data not sufficient to determine the level of susceptibility).

† P = poor freeze tolerance; F = fair freeze tolerance; G = good freeze tolerance; U = unknown freeze tolerance.

‡ Released for commercial production in Florida.

§ 67 P 6 = 6th polycross made in 1967 crossing season. Female parent (CP 56-63) exposed to pollen from many clones; therefore, male parent of CP 70-1133 unknown. Similar explanations for CP 91-1062, CP 91-1150, CP 91-1238, CP 91-1865, CP 91-1914, CP 92-1320, CP 93-1361, CP 93-1596, and CP 94-1528.

¶ Seed cane currently being increased by Florida Sugar Cane League, Inc., for potential release.
