Hybridization of synthetic allotetraploids of S. pinnatisectum with S. etuberosum (4x-EP) with S. acaule (2n = 4x = 48) resulted in two individuals that were highly fertile, in contrast to all other progenies. The unique individuals are hexaploids, 2n = 72, while the other progenies are tetraploi...

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...

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 use of ploidy manipulations in potato breeding has been successfully applied by breeders at the International Potato Center (CIP) as a tool for germplasm enhancement and for the introduction of desirable genes of wild species into the cultivated gene pool. This methodology consists in reducin...

An international workshop on cassava genetic resources was recently held at CIAT. The main objectives of the meeting were to assess the present status of cassava germplasm conservation and use, and to examine the possibility of establishing a global network for cassava genetic resources. A global...
