The genetic resources available for cassava improvement include advanced breeding lines, collected landraces and the crops`s wild relatives. Information about the structure of these gene pools is important in the development of sound germplasm conservation and use strategies. RAPD markers have be...

The main responsibility of CIAT as a curator of the world`s cassava germplasm is to assure long-term conservation at low risk of genetic loss and to facilitate access to genetic variability. The present collection of 5477 accessions is maintained both in the field and in vitro at CIAT headquarter...

In large ex situ germplasm collections, such as that maintained at CIAT for cassava, it is common to observe duplicates. The presence of duplicate clones increases the cost of conservation without contributing to representation or the available genetic base for crop improvement. To identify group...

Esterase isozymes were chosen for fingerprinting CIAT`s cassava germplasm colleciton, because of (1) their technical repeatability; (2) high polymorphism (i.e., many alleles per locus); and (3) high numner of bands detectable in cassava clones (i.e., at least a few loci are expressed). A total of...

The construction of a detailed genetic map of cassava (Manihot esculenta Crantz) will be useful to tag agronomically important trais as well as to isolate and to clone cassava genes in the future. This map will also contribute to the understanding of cassava genomic structure and evolution. As a ...

Although world cassava production has been increasing, it is shown that considerable cassava yield gaps still exist. Constraints are divided according to being endogenous and exogenous to the (plant and) production system. It is indicated that besides these constraints, considerable "adoption con...
