 en Evaluation of accessions of South African sorghum germplasm for use in the development of improved varieties

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.
