ResumoThis study aimed to evaluated the agronomics charactheristics e the technological attributes of the sixteen genotypes in the first ratoon crop when growth in the environmental conditions of the Aparecida do Taboado – MS. The experiment was conducted at the Farm Macuton 3071, on a Onisoil. The genotypes were evaluated on a randomized complete block design with three replications. The agronomic evaluations were carried out from October of 2006 to September of 2007 and consisting of: tillers number, diameter and weigth of stalk, nodes an leaf area. The technological avaliation were: total solubles solids (brix) in the juice, sucrose (pol (%)) in the juice, juice purity, cane fiber, reducing sugars (Ar (%)) in the juice and recoverable total sugar (ATR) in the juice at 254,314,344 and 374 days after the first cut. The leaf area and dry mass of green leaf, associated to others components of production, contributed to the best performance of the genotypes. The clones CTC941150 and CTC921894 presented TCH bigger, respectively, 159,38 t ha and 106,41 t ha (harvest in the July), the clones did not differ between you for the technological characteristics, except for the variable fiber (bigger value presented by the clone CTC941209 with 15,06 % and the least value for the clones CTC943218 and CTC921852, respectively, 11,66 and 11,93 %). For the characteristic conditions of an environment of production D, they stood out the clones CTC941150 and CTC921894. Key – Words: Saccharum spp, cycle, performance, maturation, productivity.
