Nematology , 2008, Vol. 10(5), 777-779 Short communication Altered reproduction response of Meloidogyne hapla on Solanum genotypes caused by propagation on different tomato cultivars J.G. (Hans) VAN DER B EEK 1 , ∗ and Leo M. P OLEIJ 2 The response in reproductive ability in experiments on host-pathogen relationships is a generally accepted cri- terion for various experimental objectives like resistance and virulence. A pure and well-defined inoculum of the pathogen, resulting in consistent reproduction response, is prerequisite for a correct interpretation of these ex- perimental response data. In experiments with automictic root-knot nematodes, e.g ., Meloidogyne hapla Chitwood, 1949, race A, maintenance of heterozygosity may cause a large intraspecific variation, even by an inoculum that is derived from a single egg mass; the genetic variation be- tween monofemale lines from one egg mass of M. hapla was still considerably large (van der Beek & Pijnacker, 2008). The heterozygous nature of the inoculum may be a potentially unreliable factor in screening experiments with automictic root-knot nematodes, since shifts in the genetic composition of the inoculum may occur, for example, by propagating the nematodes on different hosts. We obtained a first indication that the propagating host may cause a
