Evaluation of information on genetic resources activities of some legumes in Ghana

Abstract

Genetic resources information on acquisition, characterization, evaluation, documentation, and distribution of I3 legumes under conservation at the Plant Genetic Resources Centre, Bunso, were reviewed as a genetic resources support component for effective management of the germplasm for crop improvement. Comparatively, in all the 13 legumes examined, detailed acquisition information on the accessions in geographical location, edaphic and climatic factors, ethno-botany, and agronomy have been documented. Out of the 13 legumes, cowpea, groundnut, African yam bean, and French beans had characterization and preliminary evaluation information (qualitative and quantitative) on their vegetative, reproductive, yield and its components. Diversity in the accessions were assessed statistically. Accessions with the maximum and minimum parameters have been indicated. The legume accessions are being conserved at 5-7 per cent moisture content and -18 ·C in deep freezers, and are being maintained as active as well as base collections for distribution, storage, and regeneration. Materials mostly distributed to users are cowpea, groundnut, bambara groundnut and lima bean with passport data. The implications of the information on effective use for crop improvement are discussed. Original scientific paper. Received 31 Oct 02; revised 4 Apr 03.
