The Research was conducted in corporation between Faculty of Agriculture, Aleppo University and General Commission for Scientific Agricultural Researches and the International Center for Agricultural Researches in the Dry Areas during three respectively seasons starting 2008/2009. Two genotypes groups were used, first group consist of 43 genotypes of barley collected from different countries. These genotypes including 15 genotypes selected from H.spontaneium and 28 lines and local varieties. This group was used for studying the variation of root traits among Syrian varieties (lines from Arabi Abiad and Arabi Aswad), Syrian elite varieties (Furat1, Furat2, Furat3, improved Arabi Abiad) and lines from H.spontaneium. The Second group consist of 139 lines of Arta x H.spontanieum41-1backcross and was used for studying the roots genetic variation and yield traits associated root traits, and to identify genes loci for yield and root and construct genetic linkage map.Seeds from Group one were planted in two different environmental locations, Tel Hadya(zone b) and Hemayma(zone c) during 2008/2009 and 2009/2010 seasons and second group was planted during 2009/2010 and 2010/2011 seasons in Breda(zone c) and Tel Hadya locations. The two groups' genotypes were planted in tissue culture laboratory at ICARDA and they evaluated under controled conditions. Molecular weights for DNA segments from first and second group were used to prepare the analysis tables. And segregation analysis using R-square was done and linkage map was drown. The research aimed to characterize barley roots and to study their genetic variations traits depending on morphological of cultivated varieties, and Syrian landraces and H.spontaneiu mlines, and analysis of variance of morphological root traits of selected barley land races and study the correlation between root and morphological performance of the plant. And mapping linkage map for genes which are controlling root traits related drought tolerance.Grain yield, kernel weight, number seeds per spike, Plant height, and spike length were evaluated. The correlation coefficients among characters were similar in the wet and dry locations. Under dry conditions, plant growth was significantly affected in most of characters measured to wet wet location. The percentage of reduction, ranging from 66.96 % to 1.90 %on grain yield and kernel weight, respectively. The injury index ranging from 2,03 to 0.02 on grain yield and kernel weight, respectively. Using GGE Biplot the genotypes were distributed in three groups, varied in their tolerance to drought stress .roots characters showed significant genotypic variation among the barley genotypes,with values ranging from 157.33 to 1053.18 (mm2)for root surface area,and the value of total root length 8.55 to 55.83cm. while the average of root diameters ranging from 0.52 to 0.64(mm),and the value of root volume rang from 25.09 to 155.1( mm3),and the longest root length range from 5.25 to 13.52(cm), and number of root per plant 3.24 to 6.26. Cluster analysis of barley genotypes based on root characteristics showed the genotypes dividing four groups, and the genotypes are grouped together were similar
