In oat (Avena sativa L.) techniques that minimize environmental effects on the expression of phenotype and facilitate the identification of high yielding genotypes are useful. Short stature and tolerance to toxic aluminum are important for the development of cultivars with adaptability to marginal areas. Thus, genotypes selected by the honeycomb method, in three different crosses, were subjected to simultaneous tests for aluminum tolerance (Al+3) and insensibility to gibberelic acid (AG3), aiming the identification of superior genotypes. This technique enabled the selection of high yielding, short stature and Al+3 tolerant genotypes and could be applied in plant breeding programs involving cultivated hexaploid oat.
