Information on the performance of cultivars at specific planting times is important, especially for the main peanut producing state in Brazil: São Paulo. This work aimed to evaluate the agronomic performance of peanut genotypes, in the Alta Paulista region, municipality of Parapuã, in the state of São Paulo, sown at the beginning of the season. The experiment was carried out in the agricultural year 2021/22, in Parapuã – SP. The experimental design was in randomized blocks, with four replications. The treatments were eleven genotypes of low oleic lowland peanut, being two cultivars: BRS 423 OL, BRS 425 OL and nine lines: 1253 OL, 1991 OL, 2010 OL, 2055 OL, 2091 OL, 2110 OL, 2173 OL, 2914 OL and 3311 OL, developed by Embrapa's PMA. The plots consisted of two lines of three meters in length, with a spacing between lines of 0.90 m, an interval between plots of two meters and a total plot of 5.4 m2. The characteristics evaluated were ring spot severity, 100-grain weight and pod yield. Although sowing was carried out in October, adverse events were observed for this season, such as a severe epidemic of ringspot, long periods of drought and high temperatures during the period of plant development. The genotypes 2173 OL, 2010 OL, BRS 425 OL, BRS 423 OL, 1253 OL, 2055 OL and 2091 OL had pod yields higher than the average of the experiment, including BRS 425 OL, 2055 OL, BRS 423 OL, 2173 OL , 2010 OL and 2914 OL also had the lowest ring spot severity scores.
