Clean stock plantlets production volumes from 2017 to 2019

Disease eradication from yam were standardized using meristem culture and heat therapy at 36 ± 0.5°C and 16 h photoperiod for 21 days, to generate clean initial stock of planting materials followed by PCR-based methods for virus indexing to confirm tha samples were cleaned from YMV (Balogun et al., 2017). Once cleaned, these plantlets constitute stocks for rapid multiplication of superior varieties, ensuring that the virus is not passed on to subsequent generations. The Temporary immersion Bioreactor System (TIBS) in liquid medium and Conventional Tissue Culture (CTC) in solid medium were further standardized for rapid propagation. The data sets show the volumes and numbers of production using each of CTC and TIBS.
