Abstract Article is devoted to the determination of yield and breeding value of low straw forms of fourspecies triticale which was obtained by crossing of hexaploid triticale with wheat spelta (Triticum spelta L.). The use of spelta (Triticum spelta L.) for crossings with triticale allowed to create fourspecies triticale forms in which we can expect improvement of quantitative and qualitative indicators of performance. Creating forms with a low straw an important task of triticale breeding because such forms are less prone to lodging than forms with a high straw. Evaluation of low straw forms of fourspecies triticale to the yield and other economically - valuable traits is an actual task. A result of crossing winter triticale and spelta (Triticum spelta L.) is the creation of sort Alcides, which is listed in the National Register of plant varieties available for distribution in Ukraine and variety Avatar presented to the further state quality testing. In addition, was created a collection of stabilized fourspecies forms of triticale. Generally accepted elements of technology growing winter triticale for this area were used in studies. Variety of winter triticale Alcides was acted as an standart. Have been identified the yield and productivity indicators of the ear, such as the mass of grain spike, spike weight, number of grains per ear, number of spikelets in the ear, etc. We found that low straw forms of fourspecies triticale are characterized higher than in standards indicators. This points to the positive effect of crossing hexaploid triticale and Spelta (Triticum spelta L.). It is shown high competitive ability of low straw forms of fourspecies triticale that support with high levels of productivity and productivity of spike. Was established that out of 20 studied samples - seven significantly exceed the standard for the productivity and do not inferior to him to the other economically - valuable traits. Number 480 showed the the highest productivity, he exceeds the standard for the yield, mass of grain from the spike, spike weight, and has other indicators on the level of the standard.
