Journal Article 2008-04

Autor: Adeniyi, O.J. Adetimirin, V.O. Ingelbrecht, I.L. Asiedu, Robert

In vitro culture media capable of regenerating moderate to high shoots and/or plantlets from meristems of two yam species – Dioscorea rotundata and Dioscorea alata within comparable duration of 10 weeks as commonly obtained in other monocots and root and tuber crops were investigated. The study c...

Dioscorea alata L. is a highly important crop, widely distributed in the humid and semi-humid tropics. Flow cytometry was used to determine the ploidy levels of 74 D. alata genotypes collected mainly from West African countries. Sixty three of the genotypes were found to be tetraploid, one was he...

Use of genetic resistance is the most practical and economic way to manage major diseases of yams. In a search for sources of resistance, 40 water yam (Dioscorea alata L.) accessions from Benin, Ghana, Nigeria and Puerto Rico were screened under natural disease infection conditions in Ibadan, Nig...

The Guinea yams, Dioscorea cayenensis Lam. and D. rotundata Poir. (D. cayenensis–D. rotundata complex), represent a highly importantcrop, widely distributed in the humid and semi-humidtropics. The ploidy levels of 170 accessions of the core set of Guinea yams from West African coun...

Cassava (Manihot spp.) improvement strategies at the International Institute of Tropical Agriculture (IITA) are discussed here in relation to the main constraints, target ecologies and utilization of exotic germplasm. Germplasm generated from IITA populations and from other African or non-African...

An agroecologically-based germplasm enhancement strategy to further broaden the genetic base of cassava in selected ecologies of Africa was initiated by CIAT and IITA in 1990. Crosses are being made at CIAT, in Colombia, using parents adapted to four different agroecologies of South America with ...
