MENDELNET <strong>2013</strong>genotypes overcame this minimum value (Graph 4). The highest protein content was found inprogenies of No. 53 (over 14%) with the maximum value in 53/3 line (18.4 %).The sedimentation test assesses the level of protein quality. Most of Syrian genotypes had highersedimentation values than Czech varieties (Graph 5). The highest values were estimated forprogenies derived from No. 53, the strain No. 53/3 reached the value of 69.9 ml.Due to their unique origin the Syrian genotypes may carry specific traits for higher tolerance todrought stress, therefore further work will be aimed at evaluation of their drought tolerance underlaboratory and field conditions. Preliminary results by Stehno et al. (2011) showed that the wateruse efficiency of those Syrian genotypes evaluated as 13 C isotope discrimination was lower thanthat of common European varieties. It suggested that they can have a good drought-tolerancepotential and can be utilized as a source of stress-tolerance traits in breeding (Dotlačil et al, 2011).cm140120100806040200EtelaMeritto46/446/546/746/946/1046/1446/1546/1646/1746/1846/2246/2346/2446/2530/330/430/630/1230/1430/1542/131/227/127/227/427/627/727/853/153/253/353/453/653/851/145/245/447/247/347/547/6Graph 1 The comparison of plant height of Syrian wheat genotypes and Czech varietiesg6050403020100EtelaMeritto46/446/546/746/946/1046/1446/1546/1646/1746/1846/2246/2346/2446/2530/330/430/630/12A30/12B30/14A30/14B30/15A30/15B42/131/227/127/227/427/627/727/853/153/253/353/453/653/851/145/245/447/247/347/547/6Graph 2 The comparison of thousand grain weight of Syrian wheat genotypes and Czech varieties159 | P age
