Selection of white oat genotypes for contrasting fungicide management conditions

Abstract The objective of this work was to select white oat (Avena sativa) genotypes for environments with and without fungicide application, as well identify relationships between meteorological variables agronomic traits. Two experiments were carried out: one the other use tebuconazole fungicide. In each experiment, 26 evaluated, conducted during ten years in same experimental area; cultivation considered environment. methodologies genotype x interaction used define ideal genotype. 'URS Corona' is an due its excellent responses environment tebuconazole. 'Brisasul', 'IPR Aphrodite', Taura' respond better However, based on multitraits, Afrodite' can be positioned or Genotypes a rust incidence lower than 15% height higher 93 cm relative humidity 70.75% have grain yield regardless use. Greater magnitudes air temperature solar radiation result oat,
