Efeito de níveis de severidade e incidência da ferrugem-da-folha e ferrugem-do-colmo no rendimento de linhagens de aveia

Abstract: Resumo -A introdução de germoplasma representa uma das alternativas para o aumento da variabilidade em aveia (Avena sativa L.), favorecendo o processo de seleção. Os objetivos deste estudo foram: a) selecionar genótipos de aveia com potencial de rendimento e adaptação às condições do Estado do Rio Grande do Sul; b) determinar a relação entre as moléstias ferrugem-da-folha e ferrugem-do-colmo sobre o rendimento; c) estimar a relação entre os critérios: severidade e incidência, para diagnóstico da intensidade da… Show more

“…In the fungicides absence, positive correlations were verified between YIELD × HW (r=0.63) and negative, between YIELD × LR (r=-0.80) and HW × LR (-0.62). Caierão et al (2001) verified the influence of LR severity levels on white oar yield and negative correlations between both variables (r=-0.34; p<0.01), indicating that the increase in LR incidence, influences white oat yield negatively under the fungicides absence.…”
