Tillering — Durum Wheat

Triticum durum Desf.

An important element of the durum wheat yield structure, determined by the plant's ability to form secondary shoots from the tillering node. It is expressed as a tillering coefficient, representing the average number of productive stems per plant.

In the reference 17 varieties crop Durum wheat, where this is mentioned in the description.

For durum wheat (Triticum durum Desf.), the productive tillering index averages 2–3 stems per plant; however, depending on the genotype and environmental conditions, it can vary from 1–1.5 to 6 or more shoots. A high tillering coefficient serves as a compensatory mechanism, allowing the target stand density to be achieved in cases of sparse emergence.

The realization of tillering potential directly depends on the seeding rate and the level of agronomic practices. In dense sowings, the plants' ability to form lateral shoots decreases, and the primary role in yield formation shifts to the number of plants per unit area. Durum wheat possesses lower ecological plasticity than soft wheat, making its tillering more sensitive to moisture availability and nutrition.

A key factor for yield and grain quality is the synchrony of shoot development. Stems of different ages often produce less plump grain, which negatively affects the vitreousness and protein content indices, both of which are critical for durum wheat.
