Resumo

 

The aim of this study was compare some techniques to assess the adaptability and stability seeking the selection of wheat genotypes in Paraná State. The grain yield data were obtained from trial experiments of the Value of Cultivation and Use, as assessed in 44 different locations in distributed environments and sowing date. The study of adaptability and stability were evaluated based on Eberhart and Russell (1966), Lin and Binns (1988) revised by Carneiro (1998), Porto, Carvalho and Pinto (2007) and Rocha et al. (2005). The methods of Eberhart and Russell (1966), Lin and Binns (1988) revised by Carneiro (1998), and the method of Porto, Carvalho and Pinto (2007) showed similar results. These methods were superior to the method of Rocha et al. (2005), which was sloppy in the selection process. The method of Porto, Carvalho and Pinto (2007) had the advantage of simplifying the analysis of adaptability and stability.
