Rice (Oryza sativa) cultivar Azucena--belonging to the Japonica subspecies--exudes high strigolactone (SL) levels and induces high germination of the root parasitic plant Striga hermonthica. Consistent with the fact that SLs also inhibit shoot branching, Azucena is a low-tillering variety. In contrast, Bala, an Indica cultivar, is a low-SL producer, stimulates less Striga germination, and is hi...

The agromorphological and genetic parameters of sorghum are important keys in rainfed production processes. To know the diversity characteristics under striga infestation this cereal Sudano-Sahelian zone Cameroon, a survey near to 230 farmers were done. Survey was followed by collection accessions 2015 2016 16 villages 4 Divisions namely Mayo-Danay, Mayo-Kani, Mayo-Louti Mayo-Rey North. field t...

Identifying efficient testers for separating maize (Zea mays L.) inbred lines into heterotic groups can facilitate the development of superior hybrids. Striga-resistant yellow-maize developed at International Institute Tropical Agriculture (IITA) do not have well established groups. This study was conducted to identify classifying Thirty were crossed with three having varying levels resistance ...

Maize (Zea mays L.) breeders in the West and Central Africa have developed commercialized extra-early early-maturing maize hybrids, which combine high yield potentials with tolerance/resistance to drought, low soil-N Striga infestation. Hybrids of both maturity groups not been investigated for tolerance plant density N application are new farmers; th...

The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Up to now, several of these germination stimulants have been isolated and identified in the root exudates of a series of host plants of both Orobanche and Striga spp. In most cases, the compounds were shown to be isoprenoid and belong to ...

Striga hermonthica is a severe problem in the cereal growing regions of Northern Ethiopia. Nineteen Striga population samples were evaluated for their virulence against two resistant sorghum varieties currently being promoted for use in the area using an in vitro system. Nine out of the 19 populations tested were able to attack the resistant sorghum varieties (SRN 39 and P-9401). Most of the hi...

Striga gesnerioides is a root hemiparasite that primarily parasitizes dicotyledonous species, including cowpea (Vigna unguiculata L.) and other legumes. Based on the differential resistance response of various cultivars, landraces, and breeding lines, it has been proposed that several distinct races of cowpea-parasitic S. gesnerioides exist in West Africa. In this study, we used amplified fragm...
