Flowering intensity in white yam (Dioscorea rotundata)

Autor: Hamadina, E.I. Craufurd, Peter Q. Asiedu, Robert

White 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 rat...

Duration from vine emergence to flowering suggests a longday or rate of change of photoperiod response in white yam (Dioscorea rotundata Poir)

Autor: Ile, E.I. Craufurd, Peter Q. Asiedu, Robert Battey, N.H.

The objective of this study was to quantify the effect of photoperiod on the duration from vine (shoot) emergence to flowering in white or Guinea yam (Dioscorea rotundata). The duration from vine emergence to flowering in two clonal varieties of yam (TDr 131 and TDr 99-9) was recorded at 10 diffe...

Dormancy in yams

Autor: Craufurd, Peter Q. Summerfield, R. Asiedu, Robert Prasad, P.

The tubers of yam, principally those of Dioscorea rotundata (white Guinea yam) and D. alata (water or greater yam), are important staple foods and sources of carbohydrate in West Africa. Yams are grown in diverse environments – from the high-rainfall forest zone on the coast to the seasonally ari...
