Comparison by Morphological Characters of Two New Varieties of Winter Wheat Plants

Abstract

Some current studies on morphological, biochemical, molecular of wheat plants could be used in the progress of varieties ' improvement, adapted to current requirements (Black and Halmer, 2006). Board genetic dowry and wheat crop conditions usually lead to characteristic expression of plant morphology. In winter wheat, both in the case of a Phyton and a Foxyl varieties, some new directions have been found, which have recently been improved. Thus, in the two variety comparison, the straw was shorter in the hybrid with 6 cm. The basal internode (the third of top) was 1 cm longer in the variety, with its thickness between the same limits in both forms (3.1-3.2 mm). The sub-apical internode measured less 1 cm in the Phyton, and the apical internode was shorter by 2-4 cm in the Foxyl. The ear had the longest in the Foxyl, but the weight of the spikes was similar (ears were dominated by 2.1-2.3 g). Each spikes contained 16-17 spikelets in both forms. Spikelet had an external glume and inferior palea shorter to the Phyton, and the awn was longer 2-3 cm in the sema variety. The medium spike contained 15-16 more grains in the Phyton, and the total mass of the grains in a spike weighed more with 0.2 g in the same variety. The grains were longer by about 1.0 mm and the thickness was 0.4-0.5 mm more both in the Foxyl variety. The mass of thousand grains in smaller limits was at Phyton (33-36 g), while the Foxyl had the much larger grain weight (45-51 g). Between the morphological characters of the plants, significant positive correlations were obtained only between the components of the spikes in both forms. Un important links were obtained between the characters of the straw with the other plant elements in the Phyton and significant linkages under the same conditions in the Foxyl. Both forms of winter wheat demonstrated through the morphological characters manifested, good zonal adaptability.
