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...

DNA fingerprinting to confirm possible genetic duplicates in cassava germplasm
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...

Esterase isozyme fingerprinting of the cassava germplasm collection held at CIAT
Genetic studies of two isozyme loci have been carried out in root tips of eight cassava F1 progenies using polyacrylamide gel electrophoresis. Two loci, esterase-1 (East-1), the most distant cationic region, and glutamate oxaloacetate transaminase-1 (Got-1), the most proximal anionic region, were...
