Crop wild relatives are a valuable source of genetic material for improving cultivated crops. However, feral populations—self‐sustaining plants that have escaped cultivation—are often mistaken for wild relatives because they exhibit traits such as seed dispersal and dormancy, which resemble wild forms and support persistence in natural habitats. This study examined the genetic diversity, population structure, and morphology of...

Estimating the frequency of long‐distance pollination is important in cultivated species, particularly to assess the risk of gene transfer following the release of genetically modified crops. For this purpose, we estimated the diversity and origin of fertilizing pollen in a 10 × 10 km French oilseed rape production area. First, the cultivar grown in each field was identified through surveys to farmers and using microsatellite...
