Tissue culture, conservation biotechnology, virus indexing and seed systems of vegetative crops: A training manual

The compilation of this manual arises from the fact that knowledge on tissue culture, conservation biotechnology, virus indexing and seed systems for vegetative crops (in this case cassava and sweet potato) and associated techniques, are scattered and not readily available for use by practitioners or would-be-practitioners. This manual is a response to this gap and thus presents principles and practices of tissue culture, conservation biotechnology, virus indexing and seed systems. The manual will be used by research scientists and technicians working in tissue culture, conservation biotechnology, virus indexing and seed systems for vegetative crops. The manual could also be useful to students and lectures undertaking these modules as part of the curriculum at colleges or universities. To my knowledge, this is the first compilation on these diverse topics that are tailored to vegetative crops. Thus, this is both an opportunity and a challenge. It is our sincere hope that later issues will cover more case studies and future advances in these fields. Users are encouraged to adapt the references to their own working conditions and to add more materials as they deem fit.
