Response of maize varieties to Striga infestation

Crop Protection, 2004
Abstract Striga hermonthica is endemic in the semi-arid and semi-humid areas of Sub-Sahara Africa. This plant parasite reduces crop yields of maize and sorghum, the major staple food source of the region. Presently, there are no Striga -resistant maize varieties commercially available in Western Kenya.

TOLERANCE OF SORGHUM LANDRACES AND VARIETIES TO STRIGA (STRIGA HERMONTHICA) INFESTATION IN ETHIOPIA

Acta Agronomica Hungarica, 2001
A pot experiment was conducted at Sirinka Agricultural Research Center, Ethiopia in 1999 to evaluate the level of resistance of local and improved sorghum varieties to Strigahermonthica (Del.) Benth. The results indicate that the three exotic varieties, which were bred for striga resistance (P-9401, P-9403 and SRN-39), and two local varieties (Ayefere-

Efficacy of Herbicide Seed Treatments for Controlling Striga Infestation of Sorghum

Crop Science, 2009
Witchweed (Striga spp.) infestations are the greatest obstacle to sorghum [Sorghum bicolor (L.) Moench] grain production in many areas in Africa. The objective of this study was to evaluate the efficacy of herbicide seed treatments for controlling Striga infestation of sorghum.

Striga infestation of cereal crops – an unsolved problem in resource limited agriculture

Current Opinion in Plant Biology, 2008
The parasitic weed Striga causes devastating losses in cereal yields in sub-Saharan Africa. The parasite lifecycle is intimately linked with its host via a complex interchange of signals. Understanding the molecular basis of these interactions and of host resistance to Striga is essential for the identification of genes for improving crop yield via ...

Response of maize varieties to transplanting in Striga-infested fields

Weed Science, 2002
Abstract Striga hermonthica reduces cereal yields in large areas of sub-Saharan Africa. Recent research has shown that transplanting maize seedlings that are more than 15 d old reduced Striga emergence and improved crop yields. Field experiments were conducted in 1998 and 1999 to determine whether maize varieties with different maturity periods and ...

Responses of Mid-Altitude Maize Inbred Lines to Striga hermonthica Infestation

Cereal Research Communications, 2000
The incidence of the parasitic weeds, Striga spp. in the savanna and the mid-altitude ecology of Africa is on the increase. Eight inbred lines of maize developed for the mid-altitude ecology and a susceptible check (TZi 10) were evaluated in Mokwa, Nigeria for two seasons to determine their performance under Striga hermonthica, the most widespread ...

Strigolactones and root infestation by plant-parasitic Striga, Orobanche and Phelipanche spp.

Plant Science, 2011
Strigolactones are signaling molecules that play a role in host recognition by parasitic plants of the Striga, Orobanche and Phelipanche genera which are among the most detrimental weeds in agriculture. The same class of molecules is also involved in the establishment of the symbiosis of plants with arbuscular mycorrhizal (AM) fungi.

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.

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.

Ecological determinants and risk areas of Striga hermonthica infestation in western Kenya under changing climate

Weed Research, 2022
Abstract Striga hermonthica (Del.) Benth is a parasitic weed that is damaging major cereal crops in sub‐Saharan Africa (SSA). Although Striga is recognised as an agricultural scourge, there is limited information available indicating the extent of its ...
