A field experiment was set in the period 2014-2017 on the experimental field of the Research Institute of Field Crops of the Agricultural Academy, Chirpan. Three triticale varieties were used – the standard Colorit, and other two varieties created at Dobrudja Agricultural Institute – Gen. Toshevo, Bulgaria: Boomerang and Respect. The experiment consisted of a randomized complete block design after two predecessors – sunflower and durum wheat with four replication and plots of 10 m2 planted at a sowing rate of 550 viable seeds m−2. To achieve the aim of the study, during the vegetation of the triticale, fresh plants were taken by stages as follows: Tillering – leaves; Spike emergence – leaves, stems, spikes; Maturity – straw (leaves+stems), spikes, grains, glumes. After the two predecessors in the phase of spike emergence, the stems are the largest share of the plant, followed by the leaves and the spikes. However, the stems have a larger share after sunflower, and the share of leaves and spikes is close to the two predecessors. Although the relative share of the spikes is close after the two precursors, in the maturity phase, the relative share of the grain after durum wheat is 6.3% less than after sunflower, and the share of the glumes is 17.4% more.
