Correlations estimates and path analyses considering different cultivation environments can help electing the most important traits to increase industrial yield potential of oat genotypes and so, to assist in developing strategies to achieve genetic gains. Thus, this study aimed to estimate the correlations between traits related to industrial performance of oat cultivars grown in different environments. Also, the genetic correlation coefficients were partitioned in direct and indirect effects on industrial yield of grains by path analysis in order to identify traits that could be adopted in indirect selection strategies. In the crop seasons of 2007, 2008 and 2009, 15 oat cultivars were grown in two different places, following a randomized complete block design with four replications. Variables related to grain yield, quality and industrial yield were evaluated. In each location the phenotypic, genetic and environmental correlations among traits were estimated, followed by partitioning of genetic correlations into direct and indirect effects on industrial grain yield through path analysis. The performance and the relationships between traits were modified in response to environment effects, which can compromise the effectiveness of indirect selection. Hectoliter mass did not show a causal association with industrial yield. Grain yield, index of grains larger than 2 mm and number of grains per panicle presented positive direct effects on industrial yield of grains, however just the grain yield showed strong and stable relationship. Thus, the genetic improvement of industrial yield of grains carried out based on grain yield seems to be the most successful process of indirect selection.
