Various studies on morphological, biochemical, molecular (Martinez, Esparza-Fostre, 1998) could be used in the progress of improvement in new barley varieties. Board genetic dowry and barley culture conditions usually result in the characteristic expression of plant morphology. In the case or winter barley, there were some differences in the two forms: two rows (distichon-D) and six rows (hexastichon-H). By comparison the average values were 62-76 cm (D-H) straw length, 10.5 cm/3.2 mm-11.1 cm/3.8 mm length/ diameter of the basal internode, 28-36 cm length of the apical internode, 7.5 cm/1.45 g-7.5 cm/ 2.51 mm length/ weight of the ear, 25/10.6 mm-56/11.3 mm number and length of the spikelets, 2.8-14.5 number of sterile spikelets in a ear, 15.9-14.7 cm awn length, 22.5/1.18 g- 41.9/2.05 number and grain weights in an spike (ear), 52.3-48.6 g thousand grains weight (TGW) and 8.63/3.96 mm-9.13/3.75 mm grain sizes (length/thickness/width). Between the main morphological caries studied, significant positive correlations were obtained, which demonstrates the good adaptability of the plant to the crop area, both two- and six- rows barley.
