Has the Striga problem been solved? A field perspective critique of recent progress. [PDF]

Pest Manag Sci
The potential field efficacy of recently proposed breeding, biocontrol, suicidal germination, gene editing and transgenic solutions for Striga control is critically evaluated and mostly found wanting improvements. Abstract Three root‐parasitic witchweed (Striga) species can cause up to total loss of grain and legume crops for millions of farmers in ...

Integrated Management of <i>Striga hermonthica</i> in Sorghum Using <i>Glomus mosseae</i>, <i>Bacillus megaterium</i>, and Phosphorus. [PDF]

Plant Environ Interact
Glomus mosseae, Bacillus megaterium, and phosphorus significantly suppress Striga hermonthica, enhance sorghum growth, and improve soil fertility, offering a sustainable biocontrol strategy against Striga in nutrient‐deficient soils. ABSTRACT The root parasitic weed Striga hermonthica, a member of the Orobanchaceae family, is a major constraint to ...

Identification of QTLs for grain yield and other traits in tropical maize under Striga infestation.

PLoS ONE, 2020
Striga is an important biotic factor limiting maize production in sub-Saharan Africa and can cause yield losses as high as 100%. Marker-assisted selection (MAS) approaches hold a great potential for improving Striga resistance but requires identification

Association analysis for resistance to Striga hermonthica in diverse tropical maize inbred lines

Scientific Reports, 2021
Striga hermonthica is a widespread, destructive parasitic plant that causes substantial yield loss to maize productivity in sub-Saharan Africa. Under severe Striga infestation, yield losses can range from 60 to 100% resulting in abandonment of farmers ...

Improved methodologies for breeding striga-resistant sorghums [PDF]

Field Crops Research, 2000
Parasitic flowering weeds of the genus Striga (Scrophulariaceae) cause substantial losses in sorghum [Sorghum bicolor (L.) Moench] production in sub-Saharan Africa. Striga-resistant sorghum cultivars could be a major component of integrated striga management, if resistance was available in adapted, productive germplasm.

Breeding for Striga Resistance

African Crop Science Journal, 2017
Striga hermonthica(L.) Kuntze, a parasitic weed, is endemic in a large part of the Guinea savanna of West and Central Africa (WCA). Strigaplants do much damage underground before the parasitic plants appear on top of the soil around the maize plant. The weed, which could cause 100% yield loss in the maize crop, has defied all control efforts at the ...

Identifying suitable tester for evaluating Striga resistant lines using DArTseq markers and agronomic traits.

PLoS ONE, 2021
A desirable tester that elicits greater genetic difference in Striga resistance among test crosses in a breeding program has not been reported. Therefore, this study was conducted to characterize 30 Striga resistant yellow endosperm maize inbred lines ...

Towards effective resistance toStrigain African maize [PDF]

Plant Signaling & Behavior, 2008
The fascinating biology of Striga parasitism is manifest through a series of signal exchanges between the parasite and its host. As an obligate root hemi-parasite, Striga development is cued to exudates and solutes of host roots but with negative ramifications on host plant health.

Identification of QTLs Controlling Resistance/Tolerance to Striga hermonthica in an Extra-Early Maturing Yellow Maize Population

Agronomy, 2020
Striga hermonthica parasitism is a major constraint to maize production in sub-Saharan Africa with yield losses reaching 100% under severe infestation. The application of marker-assisted selection is highly promising for accelerating breeding for Striga ...
