The objective of this work was to evaluate the yield components of oat segregant populations subjected to different methods. Eight populations were planted in random block design with two replicates, according to three different models: spaced plant, full line and hill. Panicles with weight higher than mean plus one standard deviation were selected and measured for grain weight and grain number per panicle. Results showed a significant interaction between populations and environmental factors. Heritability was high, excepted for grain number/panicle on the full line models. Panicle weight can be an efficient trait to select genotypes in order to order increase grain yield. Keywords Avena sativa L., sowing methods, heritability.
