The resistance of two susceptible and six resistant soybean varieties to <I>Heterodera glycines</I> (SCN) was determined for six soil temperatures from 12 to 35°Cby comparing the number of cysts which multiplied with those of the susceptible variety "Lee 68" after completion of two generations at each temperature. In three populations of SCN grown on susceptible varieties the optimum temperature for nematode development ranged from 20 to 25°C, and temperatures of 12°C and 35°C were unfavourable. In two resistant varieties of the "Gedenshirazu" group the level of resistance decreased along with the rise of the temperature and became comparable to that of the susceptible variety at 25°C. The effect of temperature on the resistance was least appreciable in the "Peking" group varieties.
