This paper discusses the problems associated with the lack of precise techniques for measuring the diversity of a crop species, selecting materials for accession, and determining the appropriate size for a core collection, as well as the boundaries of a genepool. The authors list the most importa...

Cassava has a low multiplication ratio compared with other crops, especially seed-propagated crops. Rapid multiplication techniques are available to increase the multiplication ratio. Three types of ministem cuttings can be produced from a cassava stem. After sprouting in nursery beds, or polythe...

Background: Plant viral diseases present major constraints to crop production. Effective sampling of the viruses infecting plants is required to facilitate their molecular study and is essential for the development of crop protection and improvement programs. Retaining integrity of viral pathogen...
