Assessing the Suitability of Selection Approaches and Genetic Diversity Analysis for Early Detection of Salt Tolerance of Barley Genotypes

Assessment of the salt tolerance a large genotype collection at early growth stages may assist in fast-tracking improvement salt-tolerant barley genotypes breeding programs. This study aimed to investigate ability traits related seed germination and seedling performance with helping nine sequence-related amplified polymorphism (SRAP) markers detect 70 during stages. The different were exposed three concentrations (0, 100, 200 mM NaCl) evaluated for by looking percentage, index, mean time eight days as well lengths weights shoot root after 21 from sowing. results showed that genotypic variations obviously appeared under 100 NaCl, respectively. exhibited strong correlation among themselves, whereas they had poor traits. A positive was only observed fresh weight length salinity conditions. Principal component analysis revealed first two components, which explained 53% total variability, succeeded identify high one stage (germination or stage) both Cluster based on stress index grouped into four key clusters, cluster 1 2 being tolerant moderately stage; opposite found 4. According Ward’s method, ranked most (T) salt-sensitive (S) remained almost unchanged In contrast, change (MT) (MS) genotypes. SRAP divided tested distinct clusters B T MT Finally, using appropriate statistical methods presented this will be useful assessing number selecting sensitive stage.
