Abstract
AFLP analysis was used to estimate genetic variability within and among 14 populations of Striga asiaticaL. Kuntze collected from different locations within the Republic of Benin. The mean within-population genetic distances ranged from 0.028 to 0.038, while the mean among-population genetic distances ranged from 0.019to 0.088, with an assumed minimum genetic distance of0.01 in each case. Intra- and inter-population variation was reflected by a highly significant R2 of 0.61for the regression of geographic distance versus genetic distance. Interactions of the different Strigapopulations with susceptible host genotypes, 8338-1 (Zea mays) and CK60B (Sorghum bicolor),indicated a high degree of host-specialization, with CK60B failing to support growth of the parasite from any of the populations. The various Striga populations also exhibited different degrees of virulence on susceptible host plants. Our results support the hypothesis that different populations of this parasite may well be considered and treated as ecotypes in plant breeding programs developing resistance to S. asiatica.
