Evaluation of nine genotypes of oilseed rape (Brassica napus L.) for larval infestation and performance of rape stem weevil (Ceutorhynchus napi Gyll.).
The rape stem weevil, Ceutorhynchus napi Gyll., is a serious pest of winter oilseed rape (Brassica napus L.) crops in Europe causing severe yield loss.In currently used oilseed rape cultivars no resistance to C.napi has been identified.Resynthesized lines of B.napus have potential to broaden the genetic variability and may improve resistance to ins
