The region of Bolsão Sul-Matogrossense has vast areas occupied with forages, in some stage of degradation. Peanut cultivation can be an alternative for the recovery of these areas and a possibility of income for ranchers in the region. This study aimed to evaluate the agronomic performance of peanut genotypes in the edaphoclimatic conditions of the Bolsão Sul-Matogrossense region. The experiment was conducted at the Experimental Farm of the State University of Mato Grosso do Sul – UEMS, located in the municipality of Cassilândia – MS, in the agricultural year 2020/21. The experimental design randomized blocks, with four replications. Ten peanut genotypes were evaluated, seven lines (2133 OL, 1253 OL, 2055 OL, 2010 OL, 1944 OL, 1973 OL and 2101 OL), two cultivars (BRS 421 OL and BRS 423 OL), both developed by the Peanut improvement from Embrapa and an Argentine cultivar from El Carmen (Granoleico). The plots consisted of two lines three meters long, with a spacing of 0.90 m and a useful area for evaluation of 5.4 m2 per plot. The plots were inverted and harvested 131 days after sowing, on March 30, 2021. The variables evaluated were late leaf spot severity, 100-grain weight and pod yield. The genotypes BRS 421 OL, BRS 423 OL and 2133 OL exhibited the lowest severity scores. BRS 421 OL had the highest mass of 100 grains. Finally, the highest yields were observed in the genotypes 1944 OL, 2010 OL, BRS 423 OL, 2133 OL, 1973 OL and 2055 OL, with yields exceeding 5,200 kg.ha-1, demonstrating a possible agronomic adaptation to the edaphoclimatic conditions of the region of Bolsão Sul-Matogrossense.
