Lodging — durum wheat

Triticum durum Desf.

Lodging in durum wheat is a significant agronomic and biological indicator that determines harvesting efficiency and yield preservation, which can decrease by 8–60% due to lodging. Resistance to this phenomenon is achieved through the breeding of short-stemmed forms and strengthening stem anatomy.

In the reference 288 varieties crop Durum wheat, where this is mentioned in the description.

To assess lodging in durum wheat, a visual scale from 0 to 5 points is used, where 5 points correspond to erect crops, and 1 point to severe lodging, making mechanized harvesting impossible. When recording data, the type of lodging, its nature, as well as accompanying weather conditions and stand density are taken into account.

Lodging during the grain-filling period leads to grain shriveling and a 20–30% reduction in thousand-kernel weight due to disrupted photosynthesis. Furthermore, lodged crops become susceptible to the development of septoria, powdery mildew, rust, and root rots, which significantly impairs the commercial quality of the harvest.

Breeding for lodging resistance in durum wheat is based on developing short-stemmed forms and modifying the morphological features of the stem. Improving straw strength is achieved by increasing its diameter, internode wall thickness, and raising the content of lignin and silicon.
