ABSTRACT
Apomixis genes have been successfully transferred to cassava (Manihot esculenta) by hybridizing it with the wild species, M. glaziovii. The interspecific hybrid of cassava and M. glaziovii was exposed to open pollination during three subsequent generations. Seven sibs and the maternal progenitor of the fourth generation were genotyped using five microsatellite loci previously developed for cassava. All sibs were identical with each other and with their maternal progenitor. Sibs from M. glaziovii proved to be identical when examined by the same microsatellite loci. This evidence leads to the conclusion that apomixis does occur in wild-cassava relatives and apparently has played an important role in Manihot speciation. This is the first report of nearly 100% apomixis.
