ABSTRACT
Striga species are parasitic weeds, one of the most devastating biological constraint threatening agriculture especially production of cereals in sub-Saharan Africa (SSA), causing approximately 30% to near crop failure, thus endangering the livelihood of more
than 300 million poor smallholder famers. One way of combating Striga is having natural host resistance which is cost effective and efficient for tolerance to phytopathogenic damages. Such resistance can either be due to failure of the host to stimulate germination of the parasite (pre-germination resistance) or blockage of the parasite penetration by the host (post-germination resistance). From field evaluations,
wild pearl millet (Pennisetum glaucum) accession 29 AW was shown to get less Striga attachments compared to the cultivated variety, SOSAT-C88 P10. However, the mechanism of resistance was not established. The aims of this study were to investigate pre- and post-attachment Striga resistance in pearl millet using SOSAT-C88 P10, a
cultivated susceptible pearl millet and 29 AW. Pre-germination resistance was determined using an agar-gel assay which measured the maximum germination distance (MGD), whereas post-germination resistance was determined using rhizotron basedapproach
as well as histological analyses. A high Striga germination activity was
observed in SOSAT-C88 P10 (MGD= 35.94 + 2.88> 10 mm) coupled with elevated percentage of germinated Striga seeds (>85.04%) compared to 29 AW (MGD= 7.96 + 2.75 mm
