The experiment evaluated the performance of 12 wheat cultivars indicated to be grown in the northern of Rio Grande do Sul. According to Scott-Knott’s mean comparison test, they obtained higher grain yields of Ametista, Marfím, ORS Vintecinco, TBIO Mestre, TBIO Sintonia and TBIO Sinuelo, and regarding grain quality, Ametista, Jadeíte 11, ORS Vintecinco and Topázio. According to the method by Eberhart and Russell, Ametista, BRS Marcante, TBIO Iguaçu and TBIO Sinuelo were stable in relation to productivity and hectolitre weight. Using the Lin and Binns analysis, the Ametista showed higher average yield and greater stability in the evaluated cultivation conditions, and the TBIO Sintonia is indicated for favorable environments. In reference to the AMMI method, Ametista and TBIO Sinuelo were the most stable regarding productivity, and the 2014 and 2016 harvests were stable. In relation to hectolitre weight, Jadeíte 11 and TBIO Mestre and the year 2016 showed more stability.
