Absence of genetic differentiation in performance traits of Sinapis arvensis populations from crop and non‐crop habitats across Northern Algeria: Implications for management

Abstract

Weeds not only impact food security, but also biodiversity and ecosystem services (Neve et al., 2018). They are considered among the greatest threats to agriculture, causing huge crop losses each year worldwide (Vigueira et al., 2013). Some native weed species may build up large populations, especially when provided with available habitats by anthropogenic disturbance in arable fields or ruderal sites (Neve et al., 2018). Adaptation of weed species to such habitats may occur through genetic differentiation or phenotypic plasticity (Leiss and Müller-Shärer, 2001). Knowledge of the genetic variability of weed populations from molecular markers or from quantitative genetic traits
