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...
