Abstract
The reproductive abilities of 4 races of H. glycines were compared on soybean [Glycine max] cultivars by using single cyst or mass inoculations. Progeny transfers were used to determine changes in reproduction of H. glycines. Reproduction of all races (1, 2, 3, 4) was best on ''Lee'' and poorest on PI 88788. The size of females produced and numbers of eggs per female of the different races varied with the cultivar. Races 1 and 3 appeared to contain low populations of Races 2 or 4. Races 2 and 4 were best selected by a series of transfers on ''Pickett'' soybean.
