    • Early detection of plant virus infection using multispectral imaging and machine learning 

      Grieve, B.; Duffy, S.; Dallas, M.M.; Ascencio‑Ibanez, J.T.; Alonso-Chavez, V.; Legg, J.; Hanley-Bowdoin, L.; Yin, H. (2024-07-31)
      Climate change-resilient crops like cassava are projected to play a key role in 21st-century food security. However, cassava production in East Africa is limited by RNA viruses that cause cassava brown streak disease (CBSD). CBSD typically causes subtle or no symptoms on stems and leaves, while destroying the root tissue, which means farmers are often unaware their fields are infected until they have a failed harvest. The subtle symptoms of CBSD have made it difficult to study the spread of the ...

    • Delineation of tuber development in African yam bean (Sphenostylis stenocarpa (Hochst ex. A. Rich) Harms 

      Ojuederie, T.C. (University of Ibadan, 2021)
      African yam bean (AYB) belongs to the family Fabaceae. It is an orphan crop with so many potentials that have not been well utilised. It produces both edible seeds and tubers with high nutritional values. However, the crop is grown mainly for the seeds in West Africa, but the tubers are mainly consumed in East and Central Africa. The dual food advantage of AYB is yet to be fully tapped, due to the irregular tuberization in accessions. This study therefore characterised tuber development in AYB ...
