Chemical mutagenesis is an effective tool to create a new Genetic Variation, which is the main key for breeding program in crops, this study was investigated the effects of six concentrations of sodium azide (1.5mM, 3mM, 4.5mM, 6mM and 100Mm) and the control (0 mM) on some characteristics of Syrian barley (Hordeum vulgare L.). The genotype (Alforat 5) was treated with Aqueous Sodium Azide (NaN3) solutions for 2 hours and was planted in the winter of the year 2021 at agriculture faculty in Damascus university for estimating the phenotypic and genotypic coefficient of variation, Heritability and Genetic advance. The analysis of variation indicated High Significant differences were observed among the six treatments for the five traits (length of roots, plant height, number of tillers, number of leaves and dry weight). Genotypic and phenotypic coefficients of variability were higher for number of leaves per plant, number of tillers per plant more than the other traits. Heritability ranged (0.48% - 0.89%) for roots length and number of leaves per plant respectively, while it was0.64% for dry weight.

Heritability coupled with high genetic advance was observed for number of leaves per plant, number of tillers per plant and dry weight, which indicated the importance of the additive gene action in the genetic behaviour of these traits, and the possibility to achieve genetic gain by selection during the early segregation generation.
