GUZMAN-SILOS, Tania Lizzeth et al. Stability parameters in sunflower hybrids with high oleic content. Ecosistemas y recur. agropecuarios [online]. 2017, vol.4, n.11, pp.213-222. ISSN 2007-901X.  https://doi.org/10.19136/era.a4n11.990.

Sunflower hybrids that have oil with high oleic acid content (Olisun 1, Olisun 2, Sabritas 1, Hybrid 1, Hybrid 2 and Hybrid 3) were evaluated in the environments of Venecia, Durango and Durango, Durango in the 2010 Spring-Summer cycle, and in Venecia, Durango in the 2011 Spring-Summer cycle, under a randomized complete block design with four replicates. Analysis of stability parameters revealed significant differences (p<0.05) among hybrids for oleic acid content. For grain yield, hybrid 1 was superior (p<0.05) to the other hybrids evaluated. The Eberhart and Russell model for the variables oleic acid and yield classified the hybrids as stable, with the exception of the hybrid Sabritas 1 that had significant deviation of the regression that classified it as inconsistent. Based on oleic acid content, grain yield and stability, the best hybrids were Hybrid 3 and Sabritas 1.
