Genetic effect of Striga resistance in sorghum genotypes

Euphytica, 2017
Striga is an important parasitic weed causing substantial economic losses in cereal and legume crop production in sub-Saharan Africa. Integrated Striga management approaches such as a combined use of Striga resistant varieties and Fusarium oxysporum f.sp.

Striga Resistance in the Wild Relatives of Sorghum

Crop Science, 2004
Witchweeds (Striga spp.) are noxious parasitic weeds that cause considerable crop damage in the semiarid tropics. Genetic control of striga is effective, although sources of resistance are limited in most crops. Useful resistance sources have been obtained in sorghum [Sorghum bicolor (L.) Moench], an important host crop that has coevolved with the ...

Response of IITA maize inbred lines bred for Striga hermonthica resistance to Striga asiatica and associated resistance mechanisms in southern Africa

Euphytica, 2019
Striga spp. is endemic in sub-Saharan Africa causing up to 100% yield loss equating to US$ 7 billion. Striga asiatica (with red flowers) is found in southern Africa while Striga hermonthica (with purple flowers) is found in east and west Africa. At the International Institute of Tropical Agriculture, resistance to S.

Resistance to Striga parasitism through reduction of strigolactone exudation

Cell
Parasitism with Striga poses a major threat to global food production. Striga germination and growth rely on strigolactones (SLs) exuded by crop roots under phosphate (Pi)-deficient conditions, although the mechanism of this host-parasite interaction remains elusive.

Screening of Some Cowpea (Vigna unguiculata) (L) Resistance against Striga Infestation (Striga gesnerioides)

This study aims to screen twelve cowpea breeding lines for resistance against Striga gesnerioides, a parasitic weed that significantly impacts cowpea production in sub-Saharan Africa. The research was conducted at the biological garden of Jigawa State College of Education, Gumel, Nigeria.

Screening pearl millet genotypes for resistance to Striga hermonthica and compatibility to Fusarium oxysporum f.sp. strigae

Crop Protection
Pearl millet (Pennisetum glaucum [L.] R. Br., 2n = 2x = 14) is a nutritionally rich and climate-resilient food crop cultivated globally. It is a crucial staple crop in Burkina Faso and the dry Sahel region, encompassing Niger, Mali, and Senegal. However, the yield of pearl millet is relatively low in the region (

Tropical grasses vary in their resistance to Striga aspera, Striga hermonthica, and their hybrids

Canadian Journal of Botany, 1998
The genus Striga contains some of the most damaging parasitic plant species of the world, and it causes large problems in agricultural systems of Africa and Asia. Effective, cheap, and easy applicable methods for Striga control do not yet exist. One method with great potential may be the use of resistant crops.

Combining Ability for Grain Yield of Imidazolinone-Resistant Maize Inbred Lines Under Striga (Striga hermonthica) Infestation

2011
Striga hermonthica infests cereal crops, particularly maize, leading to severe yield reduction. In Tanzania, maize is grown on about 2 million hectares but the yield obtained is very low, estimated at 1.3 tons ha–1; this is due to various factors including striga weeds. The control measures used have not been effective.

Expression of mature plant resistance to Striga hermonthica in maize

Euphytica, 2000
Twelve maize genotypes with different degrees of resistance were evaluated in plots inoculated with seeds of the phytoparasite Striga hermonthica (Del.) Benth. and in Striga-free (control) plots for three seasons between 1991 and 1993. Resistant genotypes, although showing similar levels of underground infection as susceptible 9 weeks after maize ...
