Breeding for resistant genotypes is the best strategy to offset the destructive effects of cassava mosaic disease (CMD) and cassava bacterial blight (CBB). Two sets of diallel parents were selected for the forest and the savannah ecological zones in Ghana based on good levels of resistance to CMD...

Increase grain yield potential is one of the most important objectives of any cereal crop breeding program. To efficiently develop superior rice lines by the introgression of favorable alleles for yield and yield component traits, a strategy of alternate phenotype–genotype selection was used. The...

The first part of the paper describes embryo transfer in detail. The ILRAD herd of N'Damas has been increased using embryo transfer. The ILRAD experiment requiring the majority of the embryo transfer work is a project to locate the genes responsible for trypanotolerance in the N'Dama. Two generat...

Diseases caused by viral, fungal and bacterial pathogens pose great threat to food security in Africa. Use of disease resistant cultivars is among the most preferred tactic for disease control by smallholder farmers in Africa, who cannot afford cost intensive chemical inputs or labor intensive cr...

Field and laboratory studies were conducted in Andhra Pradesh, India, to evaluate the effectiveness of a rapid screening method using Perl's Prussian blue stain for screening grain samples from different pearl millet genotypes for zinc (Zn) content. A total of 29 entries representing a wide range...
