Resumo: | The ring spot is a virus caused by species of the Tospovirus genus, it can also cause spots on peanut grains. Information on symptoms in grains is scarce in Brazil. Because of this, the objective was to evaluate stains on peanut grains produced under high severity of ring stain. 26 lines and the cultivar BRS 423 OL, developed by the Embrapa Peanut Breeding Program, were evaluated in the 2019/20 harvest in Tupã-SP, under a severe ring spot epidemic. Each plot had two lines with three meters in length spaced 0.90 m between lines. The plots were inverted at 122 days after sowing. Four samples of 200 grams of each genotype were collected, in a completely randomized design, and the grains stained with ring stain symptoms (presence of irregular stains, redness, cracks in the films and deformations in the grains) and healthy grains were identified to determine the mass and the percentage of spotted grains. The strain 18-2131 OL had the lowest mass and the lowest percentage of spotted grains (20.1%); strains 19-2584 OL, 18-2136 OL, 18-2042 OL and 18-2250 OL showed less than 30% of spots; the BRS 423 OL cultivar showed less than 32% of grain stain. The identification of genotypes with less symptoms in the grains is important for the development of peanut cultivars with better grain quality. |

La información sobre los síntomas en los granos es escasa en Brasil. Debido a esto, el objetivo era evaluar las manchas en los granos de maní producidos bajo alta severidad de la mancha de anillo. Se evaluaron 26 líneas y el cultivar BRS 423 OL, desarrollado por el Programa de Mejoramiento de Maní Embrapa, en la cosecha 2019/20 en Tupã-SP, bajo una epidemia severa de mancha anular. Cada parcela tenía dos líneas con tres metros de longitud espaciadas 0.90 m entre líneas. Las parcelas se invirtieron a los 122 días después de la siembra. Se recogieron cuatro muestras de 200 gramos de cada genotipo, en un diseño completamente al azar, y se identificaron los granos manchados con síntomas de anillo (presencia de manchas irregulares, enrojecimiento, grietas en las películas y deformaciones en los granos) y se identificaron granos sanos para determinar la masa. y el porcentaje de granos manchados. La cepa 18-2131 OL tuvo la masa más baja y el porcentaje más bajo de granos manchados (20.1%); las cepas 19-2584 OL, 18-2136 OL, 18-2042 OL y 18-2250 OL mostraron menos del 30% de las manchas; El cultivar BRS 423 OL mostró menos del 32% de la mancha de grano. La identificación de genotipos con menos síntomas en los granos es importante para el desarrollo de cultivares de maní con mejor calidad de grano.A mancha anelar é uma virose causada por espécies do gênero de Tospovirus, também pode causar manchas nos grãos de amendoim. Informações quanto aos sintomas nos grãos são escassos no Brasil. Devido a isso, objetivou-se avaliar manchas em grãos de amendoim produzidos sob elevada severidade de mancha anelar. Foram avaliadas 26 linhagens e a cultivar BRS 423 OL, desenvolvidas pelo Programa de Melhoramento do Amendoim da Embrapa, na safra 2019/20 em Tupã-SP, sob epidemia severa de mancha anelar. Cada parcela tinha duas linhas com três metros de comprimento espaçadas em 0,90 m entre linhas. As parcelas foram invertidas aos 122 dias após a semeadura. Foram coletadas quatro amostras de 200 gramas de cada genótipo, em delineamento inteiramente casualizado e identificados os grãos manchados com sintomas de mancha anelar (presença de manchas irregulares, avermelhamento, rachaduras nas películas e deformações nos grãos) e dos grãos sadios, para determinar a massa e a porcentagem de grãos manchados. A linhagem 18-2131 OL apresentou a menor massa e a menor porcentagem de grãos manchados (20,1%); as linhagens 19-2584 OL, 18-2136 OL, 18-2042 OL e 18-2250 OL apresentaram menos de 30% de manchas; a cultivar BRS 423 OL apresentou menos de 32% de mancha nos grãos.
