Resumo: New peanut lines selected from the breeding programs hould also be planted in large plots next to grower´s fields. Nine peanut breeding lines and cultivars were evaluated in Tupã, SP, during the 2019/2020 growing season in an experiment comprising three planting dates in large plots of six rows of ten meters. Cultivation management was as the indicated for the peanut crop in São Paulo. Plots of the second and third planting dates were infested by vírus, with symptoms characteristic of GRSV (Groundnut Ringspot Virus). Each of these plots was then evaluated for the number of plants with vírus symptoms. Yield data showed the highest values in the first planting, and a decrease in the second and third planting date.  Among all genotypes tested, line 11.20 showed the highest yield especially at the first planting date. Line 10.677 showed a good yield stability and the highest average yield over the three planting dates. This line also presented the lowest number of vírus infested plants, indicating a potential for vírus resistance.

Nueve líneas y cultivares de maní fueron evaluados em el período 2019/20 mediante um experimento instalado em tres épocas de siembra em parcelas de seis surcos de diez metros de longitude. El manejo del cultivo fue igual a um campo convencional de maní. En las parcelas instaladas la segunda y terceira época ocurrió uma infestación por tospovirus GRSV, por esse motivo fueran evaluadas  el número de plantas com sintomas. Los datos mostraron los mayores rendimentos en la primera época de siembra, disminuyendo em la segunda y terceira épocas. Entre los genótipos evaluados, la línea 11.20 evidenció un alto potencial productivo, especialmente en la primera época. La línea 10.677 presentó mayor estabilidade productiva y el máximo rendimento promedio de las tres épocas. Esta línea tuvo también el menor número de plantas infestadas por vírus, presentando potencial de resistência a la enfermedad.Novas linhagens destacadas do programa de melhoramento de amendoim devem passar por cultivos experimentais em parcelas amplas junto a campos de produtores. Nove linhagens e cultivares de amendoim foram avaliados no município de Tupã, SP, na safra 2019/2020, em um experimento em campo, semeados em três épocas durante o ciclo de cultivo, em parcelões de seis linhas de dez metros. O manejo de cultivo foi o utilizado regularmente para a cultura de amendoim. Nas parcelas semeadas na segunda e terceira épocas, ocorreu infestação por vírus, caracterizado como o tospovirus GRSV, tendo assim, cada parcela sido avaliada quanto ao número de plantas com sintomas da virose. Os dados obtidos mostraram as maiores produtividades na primeira época de semeadura, decrescendo na segunda e na terceira época. Entre os genótipos avaliados, a linhagem 11.20 obteve alto potencial produtivo, especialmente na primeira época de semeadura. A linhagem 10.677 apresentou maior estabilidade produtiva, a maior produtividade na média das três épocas de plantio, além do menor número de plantas infestadas com vírus, indicando potencial de resistência à doença.
