Tzi (tropical Zea inbred) lines 1, 3, 4, 8 to 13, 15, 17, 18, 24, 25, 27, 28 and 30 are currently at the S6 stage of inbreeding; they have been selected for resistance to maize streak virus (MSV) throughout the inbreeding process using artificial field infestation with viruliferous leafhoppers. M...

Biotic constraints (insects, diseases, parasitic weeds) and abiotic stresses (drought) are widespread and pose a constant threat to maize production worldwide. Tropical environments provide the greatest opportunity for evolution of insects and diseases because of the favourable year- round climat...

A parasitic weed, Striga hermonthica (Del.) Benth., infects millions of hectares of arable land in sub-Saharan Africa, and it threatens production of cereal crops. The objectives of this study were to investigate inheritance in maize (Zea mays L.) inbred lines of tolerance and resistance to S. he...

One hundred elite, open-pedigree tropical and subtropical inbreds of maize (Zea mays L.) that had been screened in 60 tropical trials were evaluated as inbreds and in testcrosses in Nigeria. The 24 superior inbreds among these were chosen to create two diallel sets for evaluation of grain yield a...
