Badu-Apraku, B.Olakojo, S.A.Olaoye, G.Oyekunle, M.Fakorede, M.A.B.Ogunbodede, B.A.Aladele, S.[Two extraearly maturing white maize hybrids released in Nigeria]Two extraearly maturing white maize hybrids released in Nigeria

The parasitic angiosperms, Striga hermonthica and S. gesnerioides, obligate root parasites endemic in sub-Saharan Africa, constitute severe constraints to cereal and legume production in West and Central Africa. Over the years, a range of effective component technologies has been identified for S...


Emechebe, A.M.Ellis-Jones, J.Schulz, S.Chikoye, D.Douthwaite, BoruKureh, I.Tarawali, G.Hussaini, M.A.Kormawa, P.M.Sanni, A.[Farmer perception of the Striga problem and its control in northern Nigeria]Farmer perception of the Striga problem and its control in northern Nigeria

An extra-early maturing white-grained, flint/dent maize (Zea mays L.) population, TZEE-W Pop STR C4 (Reg. No. GP-576; PI 657704), has been developed at the International Institute of Tropical Agriculture. The population has moderate levels of resistance to Striga hermonthica (Del.) Benth. It was ...


Badu-Apraku, B.Ewool, M.Yallou, C.G.[Registration of striga-resistant tropical extra- early maize population]Registration of striga-resistant tropical extra- early maize population

Striga aspera and S. hermonthica are sympatric in Africa. Each may serve as virulent gene reservoirs for the other if they hybridize and their hybrids are virulent and fertile. Intraspecific and interspecific crosses were made within and between the species, and reproductive success was determine...


Aigbokhan, E.I.Berner, D.K.Musselman, L.J.[Reproductive ability of hybrids of Striga aspera and Striga hermonthica]Reproductive ability of hybrids of Striga aspera and Striga hermonthica

For the first time in sterile nutrient media in the absence of the host plant, different forms and rates of nitrogen compounds were screened for their effect on S. hermonthica Benth. shoot development beyond seed germination. There was no shoot formation beyond the inoculation stages when S. herm...


Igbinnosa, I.Cardwell, K.F.Okonkwo, S.N.C.[The effect of nitrogen on the growth and development of giant witchweed, Striga hermonthica Benth: effect on cultured germinated seedlings in host absence]The effect of nitrogen on the growth and development of giant witchweed, Striga hermonthica Benth: effect on cultured germinated seedlings in host absence

IITA has been breeding maize for Striga tolerance/resistance (STR) since 1982. Populations of Striga hermonthica from Nigeria have been used to challenge maize germplasm. Initially (1982-1984), field screening was done under natural infestation, but variability both within sites and across years ...

Autor: Kim, S.K.

Information on current progress in the refinement of screening techniques identification of resistant germplasm and breeding lines and assessment of crop losses due to striga attack is presented. A new laboratory-cum-pot steel mesh roll technique which permits interaction of stimulants with soil ...
