REPRODUCTION OF PLANT-PARASITIC NEMATODES ON WINTER RAPESEED (BRASSICA-NAPUS SSP OLEIFERA)

The reproduction of isolates of five plant-parasitic nematode species on the winter rapeseed cultivars Bridger, Gorzanski, H-47, Lindora, and Viking was evaluated. Each cultivar was a good host for Helicotylenchus pseudorobustus, Meloidogyne hapla, and M. incognita. All rapeseed cultivars were poor hosts far Pratylenchus scribneri, in comparison with a susceptible reference host. Heterodera glycines females rarely developed on any cultivar, but low numbers of juveniles invaded roots and males occasionally reached maturity.
