Controle genético da antracnose foliar em milho

Abstract: Em experimento realizado em casa de vegetação com quatro linhagens e dois híbridos de milho (Zea mays), verificou-se variabilidade para resistência a queima foliar causada por Colletotrichum graminicola avaliada por meio das variáveis área total de lesão por planta (ATL), área média de lesão (AML), comprimento total de lesão por planta (CTL), comprimento médio de lesão (CML) e número de lesões por planta (NL). Quando dois isolados de C. graminicola foram inoculados nessas linhagens e em híbridos de milho não f… Show more

“…The coefficients of variation for the three experiments were of low magnitude, with range of 6.26 to 15.96% (Table 2). These values are considered suitable for field trials involving the pathogen x host interaction, and are close to those obtained by other researchers in the same pathosystem (Coêlho et al 2001, Rezende et al 2004, Matiello et al 2012.…”

“…The use of resistant genotypes is the main and most effective management strategy in controlling anthracnose leaf blight in maize (Coêlho et al 2001, Ferreira and Casela 2001, Rezende et al 2004. Most studies on the inheritance of maize resistance to this disease estimated the presence of few genes controlling the character, with predominance of additive genetic effects over the dominant (Lim and White 1978, Carson and Hooker 1981, Badu-Apraku et al 1987, Coêlho et al 2001, Rezende et al 2004.…”

“…Genetic resistance for maize ALB can be considered a more efficient and less costly control method when compared to fungicide control (Coêlho et al 2001). However, the development of cultivars with genetic resistance to disease is costly and laborious, since it involves numerous selection cycles and favorable environmental conditions for the pathogen's development, as well as for the expression of resistance in segregating populations.…”

“…O gênero é o causador da antracnose da soja (COSTA, 2006), da ramulose (SILVA et al, 2010) e também a antracnose (SALUSTIANO, 2014) em algodão e da antrocnose do colmo e foliar do milho (COÊLHO et al, 2001).…”
