Examination of genotype × environment interactions by GGE biplot analysis in spring durum wheat

Published on

A study was conducted to examine the effects of genotype
× environment interaction (GEI) on grain yield, its
components, and quality characteristics using genotype
main effect (G) plus genotype × environment interaction
(GE) (GGE) biplot analysis. Significant differences were
observed among cultivars in grain yield, yield components,
and quality traits and the relationship between yield
components was used to identify three groups. Positive
correlations were found between quality parameters and
yield components, whereas correlations of quality
parameters with yield and yield components were negative.
The GGE biplot indicated that E6 (single irrigated location
at Diyarbakir) was an ideal environment for all traits and E5
(rainfed locations at Diyarbakir) was a highly efficient model
for quality parameters. The biplot analysis showed that
Zenit was the best cultivar in terms of yield and quality and
Zühre was efficient for quality parameters only and hence
these two genotypes can be recommended to Southeastern
Anatolia Region in Turkey.
