Avedi, E.K.Ochieno, D.M.Ajanga, S.Wanyama, C.Wainwright, H.Elzein, A.Beed, Fen D.[Fusarium oxysporum f. sp. strigae strain Foxy 2 did not achieve biological control of Striga hermonthica parasitizing maize in Western Kenya]Fusarium oxysporum f. sp. strigae strain Foxy 2 did not achieve biological control of Striga hermonthica parasitizing maize in Western Kenya

Secondary traits can improve precision with which drought or low soil nitrogen (low-N) tolerant maize (Zea mays L.) genotypes are identified, compared to measuring only grain yield under each stress. The objective of this study was to identify secondary traits for indirect selection for yield imp...


Badu-Apraku, B.Akinwale, R.O.Ajala, S.O.Menkir, A.Fakorede, M.A.B.Oyekunle, M.[Relationships among traits of tropical early maize cultivars in contrasting environments]Relationships among traits of tropical early maize cultivars in contrasting environments

Maize production is constrained by Striga hermonthica in Mali leading to high yield losses. Breeding resistant hybrid maize is a promising alternative for increasing farmers’ income. The objective of this study was to evaluate the response of test crosses to Striga hermonthica and identify high y...


Sangaré, S.Menkir, A.Ofori, K.Gracen, V.[Combining ability for grain yield, agronomic traits and striga hermonthica resistance of yellow endosperm maize]Combining ability for grain yield, agronomic traits and striga hermonthica resistance of yellow endosperm maize

The nature of interrelationships between soil pasteurisation, and increased soil N content, on the severity of Striga hermonthica infection in maize was studied in pot experiments in the screen-house. An initial experiment revealed that there was no significant difference in amount of S. hermonth...


Ahonsi, M.Berner, D.Emechebe, A.Lagoke, S.T.O.[Effects of soil pasteurization and soil N status on severity of Striga hermonthica (Del.) Benth. in maize]Effects of soil pasteurization and soil N status on severity of Striga hermonthica (Del.) Benth. in maize

The GGE biplot tool has potential for determining combining ability effects, identifying distinct heterotic groups and efficient testers in a line × tester study. However, its use for such analysis has not been adequately explored. The objectives of this study were to (i) assess combining ability...


Badu-Apraku, B.Akinwale, R.O.[Biplot analysis of line X tester data of maize (Zea mays L.) inbred lines under stress and nonstress environments]Biplot analysis of line X tester data of maize (Zea mays L.) inbred lines under stress and nonstress environments

Seeds of Striga asiatica and S. hermonthica were separated from soil using a wet sieve method with a 2.5 smallcap˜M sucrose flotation solution and 250- and 150-µm mesh screens. In 34 fields, the av. and range of seeds/100 g of soil were 8.2 and 0-75, resp. Seeds were recovered from 28 of the 34 f...


Hartman, G.L.Tanimonure, O.A.[Seed populations of Striga species in Nigeria]Seed populations of Striga species in Nigeria

Twelve samples of Striga hermonthica seed were collected from four host crops [millet (4), sorghum (4), a sorghum/millet intercrop (3) and maize (1)] from all the main areas of S. hermonthica infestation in Nigeria and were tested on eight genotypes of three test crops [maize (4), sorghum (2) and...


Kim, S.K.Akintunde, A.Walker, P.[Responses of maize, sorghum and millet host plants infestation by Striga hemonthica]Responses of maize, sorghum and millet host plants infestation by Striga hemonthica

Striga hermonthica can cause as high as 100% yield loss in maize depending on soil fertility level, type of genotype, severity of infestation and climatic conditions. Understanding the mode of inheritance of Striga resistance in maize is crucial for introgression of resistance genes into tropical...


Akaogu, I.C.Badu‐Apraku, B.Tongoona, P.B.Ceballos, H.Gracen, V.Offei, S.K.Dzidzienyo, D.[Inheritance of Striga hermonthica adaptive traits in an earlymaturing white maize inbred line containing resistance genes from Zea diploperennis]Inheritance of Striga hermonthica adaptive traits in an earlymaturing white maize inbred line containing resistance genes from Zea diploperennis

Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...


Ellis-Jones, J.Schulz, S.Douthwaite, BoruHussaini, M.A.Oyewole, B.D.Olanrewaju, A.S.White, R.[An assessment of integrated Striga hermonthica control and early adoption by farmers in northern Nigeria]An assessment of integrated Striga hermonthica control and early adoption by farmers in northern Nigeria

Striga hermonthica (L) Moench, a parasitic weed species, is a major constraint to sorghum production in the savanna zones of north-eastern Nigeria. The aim of this study was to assess the influence of farmer practices on Striga infestation of sorghum fields in the region. Random sampling techniqu...


Dugje, I.Y.Kamara, A.Y.Omoigui, L.O.[Assessment of farmers' crop management practices influencing Striga hermonthiea infestation and grain yield of sorghum (Sorghum hieolor)]Assessment of farmers' crop management practices influencing Striga hermonthiea infestation and grain yield of sorghum (Sorghum hieolor)
