Abstract: The quantification and qualification of the productive potential of peanuts allow for the differentiation of cultivars and identification of the most productive ones at regional levels. This study aimed to evaluate the productivity and grain quality of peanut cultivars and genotypes cultivated in the northwest region of Paraná. The treatments were arranged in a randomized complete block design consisting of four cultivars and four genotypes, with four replications, in plots of 3.6x3.0 m composed of four rows spaced at 0.9 m. Plants were evaluated pre-harvest, at harvest, and post-harvest to characterize their productive potential. Data were subjected to analysis of variance using the F-test, and means were compared using the Scott-Knott test (p≥0.05). There were significant differences among treatments for the variables analyzed. Productivity ranged from 3225.45 kg ha-1 to 5129.31 kg ha-1. Genotypes 2173 OL and 2091 OL, and cultivars BRS 425 OL and BRS 427 OL showed the best productive performance. Cultivar BRS 421 OL and genotype 2173 OL exhibited lower severity of early leaf spot. Under the edaphoclimatic conditions of management and cultivation, the genetic origin influenced the productive potential of the tested lines.
