- Abstract
The new wheat and triticale varieties, winter forms, describe improved morphological characters (Ammar et al., 2004). The new directions mainly focus on the straw height and the components of the ear/spike (Becker et al., 2001; Cavaleri, 2002). From practice it has been shown that new varieties that form crops with relatively lower heights could register for different levels of intensification. On the other hand, the current studies on the morphological characters could be used in the improvement of varieties, adapted to the current requirements. The wide genetic endowment and the growing conditions of wheat and triticale usually lead to the characteristic expression of plant morphology (Ma et al., 2004; Kalih et al., 2014.). In the winter wheat, in case of the Mulan variety, as well as the Agentus variety, there were some new directions, which were recently improved (Chelkowski & Tyrka, 2003; Kuleung et al., 2006). Thus, in comparison with the two varieties, the straw was shorter in triticale by 10 cm. The thickness of the base straw was smaller in triticale by 1 mm. the ear had a greater length in wheat by 1 cm, instead the weight of the ears/spikes was higher in triticale by 0.5 g. the triticale contained 6 more spikelet in a spike. The spikelet had the glume and palea/lemma shorter in wheat. The average grain contained the same number of grains in both plants, and the total mass of grains in one ear weighed more than 0.5 g in triticale. The grains were longer by about 3.0 mm and thicker by 0.2 mm in the variety of triticale. The mass of one thousand grains was greater by 20 g in triticale. Specific correlations were obtained between the morphological characters of the plants. Thus, in wheat the correlation between the grain length and the other character showed insignificant links. The mass of one thousand grains correlated very positively with the weight of the grain (r = .463***) and with the thickness of the grains (r = .332***). In triticale, in all cases positive correlations were obtained. Both varieties of winter wheat and winter triticale demonstrates by their morphological characteristics, a good zonal adaptability.
