Single node cuttings from pathogen-tested in vitro plantlets of white guinea yam (D. rotundata), cultivar TDr 93–23, were cultured in tuberization and half- and full-strength Murashige and Skoog media with 5% or 8% sucrose, with or without agar, in light or darkness and at 25 or 18°C. Microtuberi...

Single node cuttings of two genotypes each of Dioscorea alata and D. rotundata from both plants grown in screen houses and in vitro plantlets were cultured in a tuberization medium. The screen house explants had significantly higher plantlet tuberization and primary nodal complex formation, and m...

The responses of 24 white yam (Dioscorea rotundata) cultivars to mechanical and vector transmission with each of three viruses infecting yams were assessed through enzyme-linked immunosorbent assay (ELISA) and symptom development. The viruses were Dioscorea alata virus (DAV), genus Potyvirus; Dio...

Hermetic cold storage without previous drying (wet–cold storage) was experimented for the preservation of yam pollen grains. Pollens collected from white yam D. rotundata and a wild relative, D. praehensilis, were stored at -80, -20, 5, and 150C in sealed packs for 2 years. Pollen samples were dr...
