The aim of this study was the agronomic evaluation of peanut genotypes in the state of Goiás. The experiment was carried out in the experimental area of "‹"‹Embrapa Arroz e Feijão, Santo Antônio de Goiás-GO, 2020/21 crop season, under a randomized block design with four replications. Â Â The treatments consisted of nine genotypes, eight lines (1968 OL, 2133 OL, 2259 OL, 2091 OL, 2010 OL, 1253 OL, 1973 OL and 1965 OL) and one cultivar (BRS 421 OL), developed by the PMA from Embrapa. The plots consisted of two lines of three meters in length, spacing between lines of 0.90 m, interval between plots of two meters and useful plot of 5.4 m2. Planting date: December 10, 2020. Crop management followed the regular recommendations for peanut in Brazil. The average stand was 14 plants per linear meter. The plots were inverted using a simple digger/inverter equipament; after the curing period in the
 field, the plots were harvested. The traits evaluated were late laef spot severity (LLSev), mass of 100 kernelsand pod yield. The cultivar BRS 421 OL had the lowest LLSsev the highest mass of 100 kernels (granulometry) and is among the genotypes with the highest productivity, along with 2259 OL, 2091 OL, 2010 OL and 1965 OL. All genotypes evaluated showed high production levels, above 5,100 kg.ha-1, in the conditions of the state of Goiás.
