Abstract:	The ability of sunflower cultivars to support reproduction of Meloidogyne arenaria, M. hapla, M. incognita, M. javanica, Helicotylenchus dihystera, Heterodera glycines and Pratylenchus alleni was invesigated in greenhouse tests. All nematode species except H. glycines reproduced well on sunflower, although some variability occurred among the cultivars. Among Meloidogyne spp., reproduction of M. javanica was highest, followed by M. arenaria, M. incognita and M. hapla. In the field, P. scribneri and Helicotylenchus pseudorobustus increased substantially in the sunflower rhizosphere
