The development of research to improve wheat began by creating local varieties with best possible yields, but also with increased adaptability) to the various crop conditions from us. The sufficiently wide genetic dowry obtained demonstrated that even in the conditions of white luvicsoil in the South, varieties with tolerance to aluminium ions can be obtained. The Albota variety obtained in 70th period and adapted under conditions have had proved new plant characteristics, required by the new intensification crop conditions. Compared to the Bezostaia 1 variety, some gains of morphological components were found, which contributed to the development over time of this new wheat breeding center. The study of morphological characters in newly created varieties), along with those of genetics and physiology, could be useful for the constant progress of wheat improvement. From the obtained data it was found that if the straw length of the two varieties was similar, its thickness at the base was higher for the Albota variety. The length of the spike/ear increased in Albota by 1.3 cm, the weight of the spike was by 0.4 g, and the number of spikelets in a spike was by 1.8. Instead, the Bezostaia 1 variety had an external glume and a slightly longer lower palea, and the number of grains in a spike was one unit longer (1 g). The grain sizes showed longer lengths and smaller thicknesses at Bezostaia 1. While the mass of one thousand grains (MTW) was larger at Albota. Positive correlations were obtained between the morphological characters, somewhat more obvious in the Albota variety. The data obtained demonstrate a progress of improving the morphological characteristics of the Albota variety, due to the gain of tolerance to the concentration of aluminium ions.
