To examine putative specialization of a hemiparasitic plant to the most beneficial host species, we studied genetic variation in performance and trade‐offs between performance on different host species in the generalist hemiparasite, Rhinanthus serotinus.We grew 25 maternal half‐sib families of the parasite on Agrostis capillaris and Trifolium pratense and without a host in a greenhouse. caricinus Long Grey-beard Grass Amphipogon strictus var.
