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 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 کاملEffects of ALS-inhibitor herbicides, crop sequence, and fertilization on natural soil suppressiveness to Striga hermonthica
Striga hermonthica remains one of the greatest biological threats to cereal production in the savannahs of sub-Saharan Africa. Control efforts at the International Institute of Tropical Agriculture (IITA), Nigeria, focus on developing integrated S. hermonthica management (ISM) options such as legume-cereal rotation, use of host–plant resistance, soil-based biological control exploiting enhancem...
متن کاملResistance to Striga hermonthica in Wild Accessions of the Primary Gene Pool of Pennisetum glaucum.
ABSTRACT Resistance to Striga hermonthica in 274 wild Pennisetum glaucum subsp. monodii and stenostachyum accessions was evaluated at Samanko, Mali in 1997 and 1998, and at Cinzana, Mali and Sadoré, Niger in 1998. Data recorded included number of striga plants per plot at least three times during the season, date of striga emergence, number of Pennisetum plants, Pennisetum anthesis date, and do...
متن کاملIdentification of Striga hermonthica-Resistant Upland Rice Varieties in Sudan and Their Resistance Phenotypes
Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...
