Conference Paper 1990

Autor: Ruredzo, T.J. Hanson, Jean

Reports the work in progress at ILCA on appropriate methods of collecting Digitaria species and multiplying these former species and Leucaena leucocephala, Erythrina brucei and Sesbania sesban in vitro. Discusses their potential use in forage genetic resources. Discusses inoculation of stem cutti...

Seven perennial species of African origin-Brachiaria arrecta, B. brizantha, B. decumbens, B. dictyoneura, B. humidicola, B. mutica, and B. ruziziensis-have been used as fodder plants, particularly in tropical America. The history of the commercial cultivars is given, and their most important attr...

Conference Paper 1994

Autor: Hanson, Jean Heering, J.H.

The genus Stylosanthes contains about 30 species of which most are native to South and Central America, except for S. erecta and S. fruticosa which are native to Africa. The seven major species that have been used as livestock feed have been widely collected and their germplasm stored in genebank...

Alternative techniques using in vitro culture have been successfully developed for the management of germplasm of Sesbania sesban. The results of a research at ILCA are presented. Techniques have successfully been developed for the initiation of cultures on Murashige and Skoog media, shoot propag...

Conservation of germplasm has traditionally relied to a large extent on storage of seeds in genebanks. However, some forage species may take a long time to research maturity and produce seeds or, in the case of grasses, have inadequate production of seeds for collection, multiplication, dissemina...

Several differnt methods using different numbers of plants and observations have been used for characterisation of germplasm. In this study two different observation strategies for characterisation were tested in order to determine the minimum number of observations and plant per accession whilst...
