In a study to map out the genes confering resistanceto African cassava msaic disease (ACMD), a cost-effective protocol for zygotic embryo culture developed at the International Institute of Tropical Agriculture(IITA) using 1/2 strenght Murashige and Skoog's basal media, was employed to germinatet...
Single node cuttings from pathogen-tested in vitro plantlets of white guinea yam (D. rotundata), cultivar TDr 93–23, were cultured in tuberization and half- and full-strength Murashige and Skoog media with 5% or 8% sucrose, with or without agar, in light or darkness and at 25 or 18°C. Microtuberi...

Scarcity of seed, pest and diseases are major constraints to yam production. Tissue culture techniques of meristem culture combined with heat therapy have been used to produce high-yielding virus-tested plantlets of root crops, which are later multiplied through micropropagation. However, the mic...

Cassava (Manihot esculenta Crantz) is a tough and productive survival crop of smallholder farmers in the tropics. It is often grown where other crops fail. Research can make important contribution to food security and economic development in cassava-growing areas. This can be enhanced through in-...

Diagnosis of virus diseases of yams at the International Institute of Tropical Agriculture (IITA) is based on the use of indicator plants, insect vectors, serological diagnostics, and electron microscopy (EM). Yam I (YVI), yam mosaic (YMV), and Dioscorea dumetorum (DdV) potyviruses even in mixed ...
A description of cassava clones by their various mechanisms of tolerance to drought is useful in selecting parental clones tor hybridization and subsequent selection of clones from their progeny, which are targeted to various agroecological zones in the Sub-sahraran Africa. Evaluation of cassava ...
The response of white yam (Dioscorea rotundata Poir.) nodal cuttings to eight different carbon sources (sucrose, glucose, mannose, maltose, galactose, fructose, lactose, and sorbitol) at two concentrations (3 and 5%) in modified Murashige and Skoog medium was investigated. The number of nodes per...
