ÂThis study aimed to evaluate the agronomic characteristics of peanut genotypes in the southeast region of the state of Mato Grosso. The experiment was installed in the experimental area of "‹"‹the Federal Institute of Education, Science and Technology of Mato Grosso – Campus São Vicente, Reference Center of Campo Verde, located in the municipality of Campo Verde – MT, in the agricultural year 2020/21. The experimental design used was in randomized blocks, with four replications. The treatments were ten groundnut genotypes, two cultivars: BRS 421 OL, BRS 423 OL and eight lines: 1253 OL, 2055 OL, 2091 OL, 2101 OL, 2110 OL, 2133 OL, 2136 OL and 2259 OL. The plots were composed 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. Plant height was evaluated at 32, 40, 56, 66, 77, 90, 104 and 118 days after planting (DAP), black spot severity, 100 grain weight and pod yield. The plant heights of the genotypes did not differ from each other only at 32 DAP. The lines 2091 OL and 2133 OL had the lowest black spot severity scores. The greatest mass of 100 grains was obtained with the cultivar BRS 421 OL. The highest yields were observed in the lines 2055 OL, 2110 OL and 2091 OL, and the line 2091 OL also had the lowest severity score.
