It is also an important food and cash crop in Malawi. A prerequisite for any genetic improvement program is knowledge of the extent of genetic variation present between cultivars, and genetic distances between them and closely related spedes. This can be achieved through characterization of germplasm either using morphological, biochemicaL or DNA markers. This study was, therefore, initiated with the aim of determining the genetic distances and relatedness of commercial cassava varieties in Malawi and identifying promising clones using amplified fragment length polymorphism (AFLP) DNA markers and morphology descriptors. It also aimed to compare morphological and molecular marker (AFLP) technologies in characterizing cassava genotypes.Collection: CIMMYT Publications Collection
