Assessment of Resistance of Azerbaijan Bread Wheat Genotypes To Terminal Heat Stress Using GGE Biplot Analysis

The article presents the results of the comparative evaluation of 10 varieties and 100 genotypes of bread wheat for 11 parameters. GGE biplot analysis based on multiple traits revealed that the Genebank accessions compared with realized and promising varieties had a wide variation. As a result of the statistical analysis 20 accessions have been selected that are highly resistant to terminal heat and have high values for studied traits. More differences between genotypes were observed in the number of grains in 30 spikes, mass of 1000 grains and chlorophyll amount. Among 20 accessions with complex indices, along with genebank accessions there were promising varieties as Guneshli, Gyrmyzy bugda, Sheki-1 and Parzivan-2. The use of selected accessions as a starting material in creation of resistant varieties is recommended.
