Evaluation of accessions of South African sorghum germplasm for use in the development of improved varieties
Wenzel, W.G.; Mohammed, J. & Van Den Berg, J.
Abstract
In order to identify better adapted open-pollinated sorghum (Sorghum
bicolor L. Moench) varieties for small-scale farmers in Southern Africa,
1825 accessions of the South African germplasm collection and other
promising varieties were screened in South Africa and Lesotho. Promising
genetic sources for ear size and grain quality characteristics, such as
hardness, colour and size, as well as resistance to aphids, stem borers and
grain moulds were identified. It was concluded that the screening and
further characterisation of the South African collection for use by
breeders could be a contribution to curb the declining sorghum production
in the region.

Résumé
Pour mieux identifier les varietes de sorgho ouvertement-pollinisees et
bien adapte pour les petits agriculteurs en Afrique australe, 1825
accessions de la collection de germoplasm de l'Afrique du Sud et autres
varietes prometteuses etaient evalues sur le champs en Afrique du Sud et
au Lesotho. Des sources genetiques prometteuses en ce qui concerne la
taille de l'epi et les caracteristiques qualitatives des graines, comme la
durete, couleur, et taille, mais aussi la resistance contre les pucerons,
les foreuses de tige et moisissures des graines etaient identifiees. On a
conclu que l'evaluation et la caracterisation de la collection Sud
Africaine pour l'utilisation dans l'amelioration peuvent contribuer
controler la reduction de la production de sorgho dans cette region.
