The association among different traits and their direct and indirect influence on yield using path analysis were conducted with 30 broad-based and diverse cassava genotypes evaluated at four agroecological zones in Nigeria. Traits evaluated include reactions of the genotypes to prevalent pest and...

This study intended to develop and/or adopt the best cryopresentation protocol for the African cassava germplasm. Eleven protocols were investigated. One protocol focused on the tolerance of pregrowth meristems to DMSO (Dimethyl sulphoxide). The other 10 were cryopresentation protocols and were e...
Some 96 accessions of cassava (Manihot esculenta) were evaluted for genetic diversity using random amplified polymorphic DNA (RAPD) primers. Ten out of 80 Primers were considered highly informative and were used to fingerprint all of the accessions. Amplification of genomic DNA with the primers r...

The comsumption of garri- a dry granule processed from cassava roots in Nigeria is now a nation-wide habit and practice. Its price fluctuates so much that the question is now being asked as to whom should the commodity be target to? The poor or the rich? This paper reports a study of the faqctors...

Fungal rots have been reported as a limiting factor to cassava production in the humid forests of Central and West Africa. Starting April 2003 tuber rots were studied for one year as part of a diagnostic survey designed to investigate biophysical and crop management factors limiting cassava produ...
