The objective of this study was to evaluate the performance of elite potato clones for agricultural and processing quality traits. The experiments were carried out in Pelotas, State of Rio Grande do Sul, Canoinhas, State of Santa Cantarina, and Londrina, State of Paraná. A set of elite clones of the Embrapa Potato Breeding Program was evaluated. The experimental design was a randomized complete block, with three replications to Pelotas and Londrina, and four to Canoinhas. This experiment evaluated total mass of tubers, commercial mass of tubers, number of commercial tuber, mass percentage of commercial tuber, average mass of commercial tuber, specific gravity, frying color and vegetative cycle. Analysis of variance for each site and mean grouping test of each trait were performed from the data obtained in the experiment. By examining the results from the perspective of identifying the most suitable clones for fresh market, where high yield potential and early maturity are essential, compared to the control cultivar Ágata, the clones that appeared as the most promising were F80-03-06 and CL02-05. For processing, for which the specific weight, frying color, tuber yield are important traits clone F81-01-06 stood out, despite not having the highest yields, it has large tubers, intermediate vegetative cycle and good suitability for frying, in comparison to . the control cultivar Asterix.
