Information about landrace diversity has practical implications for its preservation, efficient management and effective utilization in breeding programmes. The objectives of the study were to (i) compare molecular and agronomic diversity estimates of two divergent landraces (AA007/92 and AA098/9...

Assessment of genetic gain in two tropical maize (Zea mays L.) composites improved across years is critical in determining their future improvement and use as sources of inbred lines. Two genetically complementary tropical maize composites were subjected to four cycles of reciprocal recurrent sel...

Inheritance of resistance to Stenocarpella macrospora (Earle) Sutton (syn. Diplodia macrospora Earle) ear rot of maize was studied among selected maize populations in the mid-altitude (1280 m) agro-ecological zone of Nigeria. Diallel analysis among the populations showed significant values for ge...

Aflatoxin contamination caused by the opportunistic pathogen A. flavus is a major concern in maize production prior to harvest and through storage. Previous studies have highlighted the constitutive production of proteins involved in maize kernel resistance against A. flavus’ infection. However, ...
Maize (Zea mays L.) is an important staple food consumed by people with varying food preferences and socioeconomic backgrounds in West Africa (WA). Genotype by environment interactions (G×E) exist in WA implying the need for extensive testing of cultivars in multiple environments over years befor...

Sorghum (Sorghum bicolor [L.] Moench) is one of the most important cereal crops grown in the dry savannas and semi-arid regions of West Africa under rain-fed conditions. Although total sorghum production in Nigeria has increased over the years, the average grain yield on farmers' fields has remai...

Striga hermonthica is a serious threat to cereal production in the savannas of sub-Saharan Africa. Field trials were conducted in Nigeria at Abuja and Mokwa (southern Guinea savanna) in 2005 and 2006, and at Zaria (northern Guinea savanna) and Sabongari (Sudan savanna) in 2006, to evaluate the pe...

Molecular characterization is important for efficient utilization of germplasm and development of improved varieties. In the present study, we investigated the genetic purity, relatedness and population structure of 265 maize inbred lines from the Ethiopian Institute of Agricultural Research (EIA...

Striga hermonthica parasitism is a major constraint limiting Sorghum productivity in the Nigerian savanna. Field experiments were conducted in 2005 and 2006 rainy seasons to evaluate the response of sorghum varieties to striga infestation. A randomised complete block design was used to screen 12 ...
