Visual root gall severity scores for sesame cultivars inoculated with 1,000 nematode eggs sixty days after inoculation_ Values in the table are the mean of eight replicate plants_ Root gall severity was rated on a scale of 0 to 10, with 0 = no root galling, 6 = approximately 50% of the root system galled, and 10 = 100% of the root system galled (adapted from Zeck 1971)_
