Somatic polyploidization and characterization of induced polyploids of Dioscorea rotundata and Dioscorea cayenensis [PDF]

African Journal of Biotechnology, 2016
Genetic improvement of major food yams is constrained by a number of factors, such as the scarcity of flowers and lack of synchronization between male and female flowering. Consequently, somaclonal variation including somatic polyploidization has been considered as a useful tool in yam breeding.
