Different responses of sugarcane (Saccharum spp.) genotypes, relative to yield, when submitted to several changes in harvest cycles represent a problem for farmers and a great challenge for breeders, being of common interest the identification and obtaining of varieties with high agroindustrial yield, wide stability, longevity and excellent economical viability on their commercial usage. This work aimed to evaluate the agroindustrial performance of 11 clones and 15 varieties of sugarcane in a cropland microregion in central zone of Pernambuco, considering the cultivation of cane plant, ratoon and re-ratoon, and to point out the most productive genotypes. The experiment was conducted in the agricultural area of Petribú mill, in the municipality of Lagoa de Itaenga. The experiment was arranged in a randomized block design with four replications. The variables evaluated were: tons of POL per hectare (TPH), tons of cane per hectare (TCH), fiber (FIB), adjusted POL% (PCC), purity (PZA), soluble solids content (BRIX) and total recoverable sugar (ATR). The analysis of variance detected significant differences among the genotypes indicating genetic variability. The high average herdability estimation for TCH indicated a high possibility of success in the selection based on such important yield component. Through the economical analysis it was verified that varieties RB92579 and RB93509 presented the best performance for the initial season harvest.
