Three experiments were conducted in 1971 with clones obtained by hybridization in 1964, using a lattice design. These experiments were located in the Sertãozinho, Ariranha and Tapiratiba counties of the State of São Paulo. The checks utilized were the commercial varieties CB41-76, IAC50-134 and IAC51-205. Sugarcane was harvested thrice, that is plant cane (18 months), first ratoon (12 months) and second ratoon (12 months). The clones that showed good performance received the prefix IAC which were 64-257, 64-328, 64-306, 64-276, 64-368, 64-321 and 64-304.
