Ishaq, J.Meseka, S.K.[Variability and grain yield potential of pearl millet (Pennisetum glaucum (L) R. Br.) genotypes under irrigated conditions in the Sudan]Variability and grain yield potential of pearl millet (Pennisetum glaucum (L) R. Br.) genotypes under irrigated conditions in the Sudan

Drought occurs at high frequency in maize production zones in Africa. Carefully controlled moisture deficits have been imposed at anthesis and grain filling stages of maize to develop drought tolerant germplasm. The present study was conducted to examine the potential effects of drought tolerant ...


Menkir, A.Crossa, J.Meseka, S.K.Bossey, B.Ado, S.G.Obeng-Antwi, K.Yallou, C.Coulibaly, N.Olaoye, G.Alidu, H.[Comparative performance of top-cross maize hybrids under managed drought stress and variable rainfed environments]Comparative performance of top-cross maize hybrids under managed drought stress and variable rainfed environments

The majority of farmers in sub-Saharan Africa (SSA) depend on maize (Zea mays L.), which is mostly grown in drought-prone areas. Understanding the inheritance of drought tolerance would help in developing drought-tolerant maize hybrids that would help increase maize production under erratic rainf...


Meseka, S.K.Menkir AAjala, S.[Genetic analysis of performance of maize inbred lines under drought stress]Genetic analysis of performance of maize inbred lines under drought stress

Maize (Zea mays L.) landraces in the northern Guinea savanna and Sudan savanna in West and Central Africa appear to have some drought-adaptive traits. This study was initiated to assess the level of improvement in yield potential and other agronomic traits achieved under drought stress (DS) and i...


Meseka, S.K.Fakorede, M.A.B.Ajala, S.Badu-Apraku, B.Menkir, A.[Introgression of alleles from maize landraces to improve drought tolerance in an adapted germplasm]Introgression of alleles from maize landraces to improve drought tolerance in an adapted germplasm

Yield losses of maize due to drought stress (DS) in environments with limited rains can reach 100 %. Introgression of favorable alleles from diverse landraces into adapted elite varieties will improve performance, hence reducing losses. The objective of this study was to assess the performance of...


Meseka, S.K.Menkir, A.Obeng-Antwi, K.[Exploitation of beneficial alleles from maize (Zea mays L.) landraces to enhance performance of an elite variety in water stress environments]Exploitation of beneficial alleles from maize (Zea mays L.) landraces to enhance performance of an elite variety in water stress environments

There is growing interest for yellow maize among farmers and the food and feed industries in West Africa. Testing of maize hybrids in multi-location trials is crucial for identifying adapted high-yielding candidates for quick release. This study was designed to evaluate yield stability of three-w...


Meseka, S.K.Menkir, A.Olakojo, S.Jalloh, A.Coulibaly, N.Bossey, O.[Yield stability of yellow maize hybrids in the Savannas of west Africa]Yield stability of yellow maize hybrids in the Savannas of west Africa

Experiments were conducted at El Gantra farm in Sennar State, Sudan to verify the effects of sowing date on five soybean (Glycine max L. Merrill) genotypes planted at five different planting dates in 2009 and 2010. The objectives were to assess the performance of five soybean genotypes under diff...


Ngalamu, T.Odra, J.Ashraf, M.Meseka, S.K.[Effects of planting date on yield related traits of some soybean genotypes in Sennar state of the Sudan]Effects of planting date on yield related traits of some soybean genotypes in Sennar state of the Sudan

Grain yield is a complex quantitative trait that depends on a number of other traits for selection. This study was carried out to reveal the pattern of association with and contribution of traits to grain yield in two maize populations evaluated in three agro-ecological zones of South-Western Ni...


Sesay, S.Ojo, D.K.Ariyo, O.J.Meseka, S.K.Fayeun, L.S.Omikunle, A.O.Oyetunde, A.O.[Correlation and path coefficient analysis of top-cross and three-way cross hybrid maize populations]Correlation and path coefficient analysis of top-cross and three-way cross hybrid maize populations

Marker-assisted recurrent selection (MARS) is a breeding method used to accumulate favorable alleles that for example confer tolerance to drought in inbred lines from several genomic regions within a single population. A bi-parental cross formed from two parents that combine resistance to Striga ...


Abdulmalik, R.O.Menkir, A.Meseka, S.K.Unachukwu, N.N.Ado, S.G.Olarewaju, J.D.Aba, D.A.Hearne, S.Crossa, J.Gedil, M.[Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa]Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa

Striga hermonthica and drought are the major stresses limiting maize yields in sub-Saharan Africa. The search for diverse maize lines’ tolerance to drought and resistance to S. hermonthica (DTSTHR) is very crucial for yield improvement in areas affected by the two stresses. Understanding the gene...


Mengesha, W.Menkir, A.Unachukwu, N.N.Meseka, S.K.Farinola, A.Girma Tessema, G.Gedil, M.[Genetic diversity of tropical maize inbred lines combining resistance to Striga hermonthica with drought tolerance using SNP markers]Genetic diversity of tropical maize inbred lines combining resistance to Striga hermonthica with drought tolerance using SNP markers
