Evaluation of Striga-resistant Early Maize Hybrids and Test Locations under Striga-infested and Striga-free Environments
Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yield and stability of performance based on multiple traits. Thirty Striga-resistant single–cross maize ...
متن کاملPrimary Haustorial Development of Striga asiatica
Hood, M. E., Condon, J. M., Timko, M. P., and Riopel, J. L. 1998. Primary haustorial development of Striga asiatica on host and nonhost species. Phytopathology 88:70-75. the host (sorghum) roots and advance into the cortex occurred within 24 to 48 h of inoculation. Penetration of the endodermis by the developing endophyte was delayed for 72 to 96 h after initial contact. However, upon penetrati...
متن کاملNovel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions
Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. Away from cultivated farmland, wild sorghum accessions grow as weedy plants and have shown remarkable immunity to Striga. We sought to determine the extent of the resistance to S...
متن کاملHorizontal gene transfer by the parasitic plant Striga hermonthica.
Horizontal gene transfer has been postulated to occur between crops to co-occurring parasitic plants, but empirical evidence has been lacking. We present evidence that an HGT event moved a nuclear monocot gene into the genome of the eudicot parasite witchweed (Striga hermonthica), which infects many grass species in Africa. Analysis of expressed sequence tags revealed that the genome of S. herm...
متن کاملGas exchange characteristics of the sorghum-striga host-parasite association.
Gas exchange characteristics are reported for both members of the sorghum-Striga host-parasite association. Both Striga hermonthica (Del.) Benth and Striga asiatica (L.) Kuntze had transpiration rates considerably in excess of those of sorghum (Sorghum bicolor (L.) Moench, cv CSH1). Stomatal conductance in both Striga spp. showed little response to periods of darkness and moderate water stress....
