Assessment of Azerbaijan Durum Wheat Genotypes Under Drought and Non-Stress Conditions

Abstract

In this study, as a genetic materials 50 wheat genotypes from National Genebank of Genetic Resources Institute of ANAS were tested in a randomized complete block design in two replications under drought and normal conditions in Gobustan and Absheron regions, Azerbaijan Republic during 2016-2017 growing season. Analysis of variance indicated that there were highly significant differences among the genotypes with regard to all the traits under two experimental condition. The correlation coefficients showed that stress tolerance index (STI), mean productivity (MP), harmonic mean (HM) and geometric mean productivity index (GMP) were the most desirable selection criteria for high yielding and drought tolerant genotypes. Principal component analysis and biplot showed that genotypes № 15, 28, 4, 13 and 6 were more stable under irrigated and rain-fed conditions. These genotypes can be recommended to be used as donor parents for drought tolerance genes in wheat breeding programs for drought-affected areas of Azerbaijan Republic.
