Conference Proceedings 1987

Autor: Hershey, Clair H.

Cassava breeders and scientists in related fields from the 3 major cassava-producing continents (America, Africa, and Asia) were brought together for the lst time to discuss the latest advances in cassava breeding research and exchange ideas on future priorities. Most breeding programs now orient...

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...

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...

Conference Paper 1984

Autor: Hershey, Clair H.

A description is given of CIAT's cassava breeding program, designed to exploit the adaptation of cassava to various physical and biological stress factors by selection over a range of moderate to high stress environments. The selection environments are described and a decentralized breeding metho...
