Il existe pi usieurs facons de conserver les ressources genetiques des cultures. La methode la moins chere et la plus simple consiste a stocker les graines. Toutefois, ce n'est pas toutes les cultures qui peuvent etre conservees sous forme de graines, car certaines se propagent vegetativement et ...

Single node cuttings from pathogen-tested in vitro plantlets of white guinea yam (D. rotundata), cultivar TDr 93–23, were cultured in tuberization and half- and full-strength Murashige and Skoog media with 5% or 8% sucrose, with or without agar, in light or darkness and at 25 or 18°C. Microtuberi...

Genetic diversity was investigated among fifty accessions of yard-long-bean (Vigna unguiculatasubspecies unguiculatacultivar group sesquipedalis) using simple sequence repeat (SSR) markers. Sixteen SSR primers were used to amplify DNA of the 50 accessions. A total of 63 polymorphic bands were det...

The genetic diversity in wild cowpea was assessed using cowpea derived simple sequence repeat (SSR) markers. A total of forty eight wild cowpea lines collected from diverse geographical locations in Africa were used for the study. Twelve SSR markers were selected for amplification of DNA of the t...

A knowledge of the extent of genetic variation in a crop is a prerequisite for its improvement. In cassava (Manihot esculenta Crantz) such knowledge is lacking especially at the DNA level. The genetic variation among 28 cassava varieties collected from different locations in the Republic of Benin...

La connaissance de l'importance de variation genetique chez une culture est necessaire pour son amelioration. Chez le manioc (Manihot esculenta Crantz), une telle connaissance manque surtout au niveau du DNA. La variation genetique parmi les 28 varietes du manioc recueillies de differentes locali...

Single node cuttings of two genotypes each of Dioscorea alata and D. rotundata from both plants grown in screen houses and in vitro plantlets were cultured in a tuberization medium. The screen house explants had significantly higher plantlet tuberization and primary nodal complex formation, and m...
