One susceptible and 6 nematode-resistant soyabean cultivars were evaluated in the field for their effects on seed yield, nematode populations, and response to the fumigant ethylene dibromide (at 105 litres/ha). The soil was a loamy sand infested with M. arenaria (race 2) and H. glycines (races 3, 4 and an unidentified race). Cultivars significantly affected yield and numbers of H. glycines but did not affect M. arenaria numbers. Fumigation increased yield and reduced M. arenaria numbers but did not affect numbers of H. glycines. The interaction between cultivars and fumigation was significant for yield but not for nematode numbers.
