Enhancing regeneration in white yam (Dioscorea rotundata) through friable embryogenic callus

Plant Cell, Tissue and Organ Culture (PCTOC)
Abstract White yam (Dioscorea rotundata) is a critical staple food and an income generating crop in tropical regions. However, its improvement via classical breeding is challenging and time consuming due to an erratic flowering pattern, poor seed set, dioecious nature, low pollen fertility and low seed germination rates. These constraints limit

Effects of Variety and Sett Weights on Sprout Emergence and Seed Tuber Yield in Dioscorea alata L. and Dioscorea rotundata Poir.

Crops
Yam is a staple crop in Africa that is constrained by its low multiplication rate. This results in a short supply of seed tubers, which is a challenge to increased production.

PROXIMATE COMPOSITION OF REGIONS OF Dioscorea bulbifera (L.) and Dioscorea rotundata (L.) TUBER DURING STORAGE

International Journal of Agricultural and Veterinary Science
There has been so much speculations about the nutritional quality of yams at different stages of storage. Sometimes tubers at post sprouting stages are crudely rejected for food without scientific evidence. This study was therefore designed to ascertain the proximate composition of two species of yam; Dioscorea bulbifera L.

Development of mapping populations for genetic analysis in yams (Dioscorea rotundata Poir. and Dioscorea alata L.)

African Journal of Biotechnology, 2011
Progress is being made at the International Institute of Tropical Agriculture (IITA, Ibadan, Nigeria) to develop molecular tools for marker-assisted selection that would complement and expedite conventional breeding approaches for genetic improvement of yams (Dioscorea spp.).

Varietal diversity and conservation of cultivated yam (Dioscorea cayenensis, Dioscorea rotundata and Dioscorea alata) in Kara region (Togo)

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2018
Yam is a strategic crop in Togo. Inventory and evaluation of cultivated varieties in different traditional agroeco-systems allows safeguard of this genetic heritage and its use in breeding programs. As welle ethnobotanical surveys were conducted in 30 localities of Kara region. The inventory allowed the recording 134 yam varieties distributed as follow
