Herbicide resistance in rapeseed

Brassica napus var. napus

This trait is a discrete genetic property of a cultivar that determines its ability to maintain viability when specific groups of herbicides are applied.

In the reference 113 varieties crop Rapeseed, where this is mentioned in the description.

Rapeseed resistance to herbicides is not a quantitative value and is classified as a qualitative varietal trait. The presence of resistance is confirmed by molecular genetic diagnostic methods, in particular PCR analysis of target genes, such as the AHAS gene for adaptation to imidazolinones, or by the results of field bioassays on plant survival under herbicide exposure.

Under production conditions, the cultivar status is defined as resistant or susceptible, with intermediate forms being undesirable due to the risk of reduced productivity. The selection of a cultivar with a specific type of resistance strictly regulates the crop chemical protection technology and requires consideration of the potential for gene flow of resistance to related weed species.
