Resumo

This work evaluated the field performance and resistance to Peronospora destructor of 46 onion cultivars in two different experiments. Two open-pollinated experimental cultivars: “Bola Precoce-Agroecológica, and “Superprecoce-Agroecológica” were more productive and resistant. The onion breeding by screenings in agroecological production systems may be an alternative to obtain germplasm less sensitive to biotic and abiotic stresses.
