Popis: Striga spp. is endemic in sub-Saharan Africa causing up to 100% yield loss equating to US$ 7 billion. Striga asiatica (with red flowers) is found in southern Africa while Striga hermonthica (with purple flowers) is found in east and west Africa. At the International Institute of Tropical Agriculture, resistance to S. hermonthica was introgressed from wild relatives into commercial maize. This study aimed at ascertaining resistance to S. hermonthica and associated mechanisms that could effectively control S. asiatica. Thirty maize inbred lines were evaluated for S. asiatica resistance using the pot culture and agar gel technique. The pot experiment was arranged in a 10 × 6 α-lattice design with three replications and the gar gel experiments were conducted in complete randomized design with four replications. Maize inbred lines were significantly different (P
