Abstract
Host-plant resistance to the parasitic weed Striga (Striga spp. Lour.) is a manifestation of one or more potential mechanisms. One of the better understood mechanisms of resistance against Striga by sorghum [Sorghum bicolor (L.) Moench] is low production of compounds by the host root that Striga seeds require as stimulants for germination. A recently developed, efficacious laboratory screening technique, the agar gel assay, distinguishes resistance to Striga among sorghum cultivars based on the capacity of their root exudates to stimulate Striga seeds to germinate in a water agar medium. This study was conducted to determine the inheritance of low stimulant production in sorghum by the use of the agar gel assay. F1, F2, and backcross progenies between resistant sorghum line 'SRN-39 and three susceptible lines, 'Shanqui Red', 'P-954063', and 'IS 4225', were evaluated for stimulant production. Segregation ratios indicated that low stimulant production is inherited as a single, nuclear, recessive gene which is largely additive in action
