Özet
The present study was undertaken to identify
the best durum wheat genotypes suitable for the
South-Eastern Anatolia Region of Turkey with
desirable grain yield and quality. In the context,
thirteen spring durum wheat genotypes were evalu ated in four environmental condition of the target
region in consecutive two growing seasons in the
year 2013-14 and 2014-15. The stability and supe riority of genotypes, and favorable testing environ ments were described by using ANOVA and GGE
biplot analysis (genotype, genotype x environment).
Genotype, environment and GEI (genotype x envi ronment interaction) was found to be highly signifi cant for multiple traits. The total variation of PCI
(principles component) and PC2 was calculated
90% for ETI (environment trait interaction), 57.35
for GTI (genotype trait interaction), and 87.5% for
GE interaction. The results of total variation of ETI
was found higher than GTI and GEI. On the other
hand, the biplot analysis showed that four mega environments occurred among ETI and three envi ronments (E1, E2 and E3) correlated with different
traits, while environments E4 did not correlated
with any traits. The environment E1 was found the
best for Grain yield, test weight, thousand kernel
weight and starch content, E2 for L*, b*, SPAD,
and E3 for zeleny sedimentation, protein content
and wet gluten content. In the biplot analysis, the
environments divided three sector based on traits.
Among the genotypes, the genotype G8 was per formed the best in all tested environments, while
G9 was found the best based on all traits. The re sults of the study showed that GGE biplot analysis
can be used as a good tool to identity of the most
suitable environment in terms of all the characteris tics as well as to identify the best genotypes for
future breeding program.
