Flowering intensity in white yam (Dioscorea rotundata)

The Journal of Agricultural Science, 2009
SUMMARYWhite or Guinea yam (Dioscorea rotundata), grown for its underground tubers, is an important food in West Africa. Progress in yam breeding is constrained by variable flowering behaviour, making hybridization difficult. Yam clones may be dioecious, monoecious or hermaphrodite with variable sex ratios.

Improving micropropagation ofDioscorea cayenensis–Dioscorea rotundatacomplex by the use of nodal cuttings and microtubers

Acta Agriculturae Scandinavica, Section B - Soil & Plant Science, 2013
Yams (Dioscorea spp.) are tuber crops used as staple food in Africa because of their nutritional value. In contrast to the inefficiency of traditional method of planting, micropropagation by nodal cuttings allows to increase the multiplication and the rapid production of pathogen-free plant material.
