Abstract
The aim of this study was to evaluate the adaptability and stability of sunflower genotypes resistant to the imidazolinone herbicides on crops as second crop, related to their grain and oil yield. The assays were conducted in six states and the Federal District in 2009 and 2010. The experimental design was randomized block design with four replications. Different methods were used to analyze the stability and adaptability. The methods of Lin & Binns modified by Carneiro, Rocha et al. and Porto et al. showed similar results. The genotype ALBISOL 20CL presented general adaptability for oil yield and the HLA genotype 211CL showed specific adaptability to favorable environments for grain and oil yield. For grain yield, the method of Porto et al. indicated the genotype ALBISOL 20 CL to favorable environments. The method of Eberhart & Russell was similar to the other three methods only in the classification of genotype ALBISOL 20CL. The two genotypes showed tolerable stability.
