Various studies on morphological, biochemical and molecular characters could be used to improve new wheat varieties. Broad genetic dowry and wheat crop conditions usually lead to the characteristic expression of plant morphology. In the case of winter wheat, the Cameleon variety, some new directions have been found, which has recently been improved, with specific characters. Thus, the straw had an average length of 58 cm, of which the basal internode (the third of top) had a length of 12 cm and a thickness of 3.2 mm, usually full marrow. The sub-apical internode measured 20 cm, and the apical internode 21 cm. The spike (ear) had a length of 8.1 cm, a weight of 2.1 g and contained 16 spikelets. The spikelet had an external glume of 8.9 mm, a lower lemma of 9.7 mm, and a 7 cm awn. A medium spike contained 49 grains, weighting 1.62 g. The grains (caryopsis type) had a length of 6.8 mm, a thickness of 2.99 mm, and a thousand grains weight of 33 g. Significant positive correlations were obtained between the morphological characters of the spike. The grains, by size, correlated less with the other characters, except the mass of thousand grains. The new cultivated variety has shown a good adaptability to a new and efficient agriculture.
