“GGE biplot” assessment of phenotypic stability of spring barley varieties

Abstract

The article presents GGE biplot analysis of results of environmental trials in 17 varieties of spring barley bred at the Plant Production Institute nd. a V.Ya. Yuriev of NAAS. The study results discriminate genotypes with stable realization of their genetic potential in a number of environments as well as genotypes combining a high level of a trait with its stable expression. The varieties Kozvan, Perl, Agrariy and Kosar were chosen as valuable source material for spring barley breeding. We think that GGE biplot can be a comprehensive alternative to the most conventional methods of assessment of adaptive features in genotypes.
