dc.description.abstractEnOver the last 20 years Cyperus esculentus (yellow nutsedge) has become invasive in south-west France. Because the genetic variation of invasive species can affect the success of management strategies, amplified fragment length polymorphism markers were used to assess the amount and distribution of genetic diversity in this clonally reproducing weed. Population samples of C. esculentus were collected mainly in south-west France, with 21 samples of C. eragrostis also included in this study. A total of 113 polymorphic loci were identified (50% of the bands scored) in C. esculentus. A low level of genetic diversity (0.140) was detected, of which 95% were partitioned among sites. The regional patterns of variation could have been caused by rapid range expansion of clones propagated by harvesting machinery. Implications of the high clonality detected in C. esculentus are discussed in the context of the development of weed management strategies: because reproduction of the weed in Haute Lande occurs by tubers only, vegetable production should be reduced in infested areas.
