Promiscuous arbuscular mycorrhizal symbiosis of yam (Dioscorea spp.), a key staple crop in West Africa

Autor: Tchabi, A. Burger, S. Coyne, D.L. Hountondji, F.C.C. Lawouin, L. Wiemken, A. Oehl, F.

Yam (Dioscoreaspp.) is a tuberous staple foodcrop of major importance in the sub-Saharan savannas ofWest Africa. Optimal yields commonly are obtained only inthe first year following slash-and-burn in the shifting cul-tivation systems. It appears that the yield decline in sub-sequent years is not ...

Optimum time for collection of root samples for chromosome observation in yams (Dioscorea spp.)

Autor: Babil, P.K. Kikuno, H. Shiwachi, H. Toyohara, H. Fujigaki, J. Fujimaki, H. Asiedu, Robert

The genus Dioscorea is considered to be one of the most difficult groups for cyto-taxonomic studies because of the large number and small size of the chromosomes. The objective of the present study was to develop an efficient method of chromosome observation by identifying the optimum time for co...

Susceptibility of yam cultivars to minisett rot pathogens

Autor: Osai, E.O. Ikotun, T. Asiedu, Robert Hahn, S.K.

The response of yam (Dioscorea) cultivars to artificial and natural infections with minisett rot pathogens was investigated. None of the 20 yam cultivars were resistant to Sclerotium rolfsii [Corticium rolfsii] or Trichoderma longibrachyatum. Cultivars TDa 84/093, 85/236, 85/257, TDr 608, 745, 81...

Production and distribution of virusfree yam (Dioscorea rotundata Poir.)

Autor: Ng, S.Y.C.

The international distribution of vegetative plant parts is restricted by the risks of introducing diseases and pests to non-infected areas. Methods used at IITA to produce and distribute virus-free yams to requesting national programs and collaborators are described. The selected yam clones are ...

Life table of the predator Alloeocranum biannulipes Montrouzier and Signoret (Hemiptera: Reduviidae) and a test of its ability to suppress populations of Dinoderus porcellus Lesne (Coleoptera: Bostrichidae) in stored yam chips

Autor: Loko, Y.L.E. Gavoedo, D.M. Toffa, J. Orobiyi, A. Thomas-Odjo, A.A. Tamò, M.

Stored yam chips are attacked by Dinoderus porcellus Lesne, which can cause significant losses. The predator Alloeocranum biannulipes Montr. and Sign. is a potential biological control agent of D. porcellus. The biology, predation and mating behaviour of A. biannulipes were investigated under lab...
