Levantamento de raças do agente causador do míldio da alface no Estado de São Paulo em 2012 e 2013

Abstract: RESUMO A alface é, entre as hortaliças folhosas, a mais importante economicamente para o Brasil. No inverno, com baixas temperaturas e com molhamento foliar, o míldio da alface, doença causada pelo agente etiológico Bremia lactucae, ocorre em praticamente todas as regiões de cultivo desta hortaliça, sendo considerada uma das doenças foliares mais severas da cultura. O objetivo deste trabalho foi identificar as raças de B. lactucae no ano de 2012 e 2013 que ocorreram nas principais regiões produtoras do Estado … Show more

“…Some isolates that are present in one area can infect lettuce cultivars from another area, even if they have resistance genes (MAISONNEUVE, 2011). This may be because of the fact that several virulence phenotypes of B. lactucae have been identified so far in Brazil (NUNES et al, 2016).…”

“…The three virulence phenotypes of B. lactucae (63/63/51/00, 63/31/19/00 and 63/63/19/00) used were from the "Júlio de Mesquita Filho" Júlio de Mesquita Filho State University Paulista. These are the most common and important virulence phenotypes in Brazil (CASTOLDI et al, 2012;NUNES et al, 2016;FRANCO et al, 2021). For each of the three B. lactucae virulence phenotypes, a separate experiment was performed with three replicates.…”

“…For Belgium, 'NunDm15' may also be exploited for resistance to downy mildew (Van Hese et al, 2016). In Brazil, in a study made by Nunes et al (2016), it is recommended to use the Dm18 and FR-38, conferred by the differentiating 'Colorado' and 'Argelès'. 'Argelès', 'Kibrille', 'Balesta', 'Colorado', 'Design', 'Bartoli' and 'NunDm15' can be used as source of resistance in lettuce breeding programs to confer resistance to M. javanica and lettuce mildew.…”

“…A alface (Lactuca sativa L.) pertence à família Asteraceae e ao gênero Lactuca, e são descritas mais de 100 espécies desse gênero. Esta hortaliça folhosa possui alta aceitação pelos consumidores, sendo considerada a asterácea mais produzida e consumida no mundo (NUNES et al, 2016;TOFOLI et al, 2014;CASTOLDI et al, 2011).…”

“…Considerando suas características para o consumo, a alface destaca-se pelo elevado teor de vitaminas A, B1, B2 e C, fibra, niacina, betacarotenos, folatos e minerais como cálcio, fósforo, magnésio, ferro, além de vários outros compostos bioativos benéficos para a saúde, com atividades anti-inflamatórias, de redução do colesterol e antibióticas (SOUZA et al, 2019;TOFOLI et al, 2014;NUNES et al, 2016).…”
