Characterization of markers linked to resistance motifs against maize lethal necrosis in Tanzanian maize germplasm

Among the biological constraints facing maize production in Tanzania is a severe occurrence of maize lethal necrosis disease (MLN) raising an urgent need for application of new approaches. A pool of 22 maize genotypes with promising resistance and susceptibility to MLN infection were evaluated by Amplified fragment length polymorphism (AFLP) DNA fingerprinting analysis to detect genetic variation in the selected lines....

Agronomic performance of pro vitamin a cassava varieties in three locations in Nigeria

In an early yellow root cassava study in 2003 to 2004, we investigated agronomic performance of pro Vitamin A (yellow fleshed) cassava genotypes in three locations in Nigeria (Ibadan, Mokwa, and Onne). Twenty-two clones and three checks were evaluated. A randomized complete block design was used with four replications. Characteristics showing significant differences among genotypes across all locations included...

Effect of native mycorrhizal fungi inoculants on the growth and phosphorus uptake of tree legumes: Erythryna brucei and Millettia ferruginea

The inoculation study was conducted in the greenhouse to investigate the effect of phosphorus (P) concentrations on growth and arbuscular mycorrhizal fungi (AMF) colonization of multipurpose tree legumes Erythrina brucei and Millettia ferruginea. Plant growth parameters (shoot length, dry weight) and P uptake increased significantly after inoculations with AM fungi, Rhizophagus clarus, Rhizophagus intraradices and the...

Survey of Turcicum leaf blight (Exserohilum turcicum) on maize (Zea mays) in major highland and mid-altitudes of maize growing agro-ecologies of Western part of Oromia, Ethiopia

Turcicum leaf blight (Exserohilum turcicum) (TLB) is a major disease affecting maize (Zea mays) in western Ethiopia. This study was designed to: assess the incidence and severity of TLB in major highland and mid-altitudes of maize growing agro-ecologies of Western Oromia, map the geographical distribution of the TLB disease in the study area, and evaluate the reaction of maize varieties under production to TLB. From...
