Variety traits

Herbicide resistance — durum wheat

Triticum durum Desf.

Durum wheat is characterized by higher sensitivity to a number of herbicides compared to bread wheat. Resistance is defined as the degree of genotype tolerance determined by genetic factors, including the presence of specific mutations in imi1/imi2 genes.

In the reference 8 varieties crop Durum wheat, where this is mentioned in the description.

Durum wheat is characterized by higher sensitivity to herbicides compared to bread wheat or barley, which often leads to phytotoxicity symptoms when using products that are safe for other cereal crops. The resistance trait is not constant and varies between varieties; however, there are genotypes that possess specific resistance to certain groups of herbicides, such as imidazolinones, due to breeding-induced mutations in the imi1/imi2 genes.

Resistance assessment is conducted through visual observations of phytotoxicity, comparative biomass analysis, and the impact on yield and grain technological qualities, including thousand-kernel weight and gluten content. High tolerance is expressed by the absence of significant differences compared to the control, whereas low tolerance leads to growth retardation, chlorosis, ear damage, and reduced productivity, which is critical for pasta production.
