| Popis: | Flaxʼs fiber yield and quality can be severely impaired due to water deprivation. Herein, 41 diverse flax accessions were evaluated for four agronomic and four root traits under drought stress (DS) and irrigated (IR) conditions. In order to identify quantitative trait nucleotides (QTNs) positively influencing the stability of these traits under DS, the stress tolerance index (STI) and trait stability index were calculated, which were analyzed using two single-locus and three multi-locus genome-wide association (GWA) methods with 170,534 single-nucleotide polymorphisms (SNPs). Significant genotype and treatment effects (p |
