| description | Zucchini (Cucurbita pepo L.) is a horticultural plant species of great socioeconomic value in tropical countries such as Colombia and Brazil. The production of zucchini is qualitatively and quantitatively affected by many diseases, especially viruses belonging to the Potyvirus (Zucchini yellow mosaic virus - ZYMV) and Comovirus (Squash mosaic virus - SqMV) groups. The primary strategy to reduce the spread of potentially damaging plant viruses is the development of genotypes with genetic tolerance; however, there are not many zucchini genotypes with multiple tolerance. Therefore, this study evaluated 66 zucchini genotypes to find sources of tolerance to the ZYMV and SqMV viruses. This experiment was conducted in a completely randomized design using genotypes from the germplasm bank of the Federal University of Uberlândia, including the genotypes: Emanuela (common commercial genotype) ‘Tronco Caserta’ (susceptible genotype) and PX 13067051 (resistant genotype). Leaf extracts containing viral particles were used as inoculant, and the distribution of grades of tolerance was recorded at the seedling stage. The lineages UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, and UFU-D×UFU-F#7#21;1 and the Emanuela cultivar are alternatives for the production of new zucchini genotypes or hybrids with tolerance to the viruses ZYMV and SqMV. More severe symptoms were observed, as well as a larger number of susceptible genotypes for the ZYMV virus, indicating that this virus has great potential for causing damage and losses to zucchini crops. |

El calabacín (Cucurbita pepo L.) es una especie de planta hortícola de gran valor socioeconómico en países tropicales como Colombia y Brasil. Su producción se ve afectada tanto cualitativa como cuantitativamente por muchas enfermedades en especial por los virus pertenecientes a los grupos Potyvirus (Virus de mosaico amarillo de Zucchini - ZYMV) y Comovirus (Virus de mosaico de calabaza - SqMV). La estrategia principal para reducir la propagación de virus vegetales potencialmente dañinos es el desarrollo de genotipos con tolerancia genética; sin embargo, no hay muchos genotipos de calabacín con tolerancia múltiple. Por lo tanto, este estudio evaluó 66 genotipos de calabacín para encontrar fuentes de tolerancia a los virus ZYMV y SqMV. El experimento se llevó a cabo en un diseño completamente aleatorio utilizando genotipos del banco de germoplasma de la Universidad Federal de Uberlândia, incluyendo los genotipos: 'Emanuela' (genotipo comercial común), 'Caserta' (genotipo susceptible) y 'PX 13067051' (genotipo resistente). Los extractos de hojas que contienen partículas virales se utilizaron como inoculantes y la distribución de los grados de tolerancia se registró en la etapa de plántula. Los linajes UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, UFU-D×UFU-F#7#21;1, y el cultivar Emanuela son alternativas para la producción de nuevos genotipos de calabacín o híbridos tolerancia a los virus ZYMV y SqMV. Se observaron síntomas más graves, así como un mayor número de genotipos susceptibles para el virus ZYMV, lo que indica que este virus tiene un gran potencial para causar daños y pérdidas al cultivo de calabacín.
