P.  aField performance and screening for resistance to Peronospora destructor of 46 onion cultivars in Brazil.h[electronic resource]  c2018  aThis work evaluated the field performance and resistance to Peronospora destructor of 46 onion cultivars in two different experiments. Two open-pollinated experimental cultivars: BBola Precoce-Agroecol??gica, and BSuperprecoce-Agroecol??gica 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.  aAdaptability Allium cepa Downy mildew Local cultivars Plant breeding1 aARA??JO, E.
