Performance and phenotypic stability of ten international varieties of wheat flour in Bolivia´s wheat areas, 2015 – 2016

Abstract

In order to determine the phenotypic stability of eleven varieties of bread wheat in the wheat areas of Bolivia, trials were established in seven locations and in four departments. The environments were identified based on its representativeness as well as by their high capacity for genotype x environment interaction discrimination. The trials were established in the 2015-2016 cropping season, under a completely randomized block design with three replications. The parametric, additive and multiplicative statistical analysis, allowed the identification of cultivars that turned out to be significantly superior to the check. The stability analysis of Eberhart and Russell, the AMMI model and the GGE biplot model are powerful tools that allowed the identification of high performance and high stability varieties. In the present research, the Reedling # 1 cultivar was the most stable in the seven environments, additionally, cultivars that exhibited specific adaptability were detected.
