The National Botanic Garden of Belgium holds a collection of wild Phaseoleae - Phaseolinae species. This collection was started in 1965 by G. Le Marchand and R. Maréchal at the Faculty of Agricultural Sciences at Gembloux (Belgium) and transferred to the Garden in 1988.
The collection covers a very wide genetic diversity. It currently includes 1886 accessions representing 225 taxa of the Phaseoleae tribe, chiefly centered on the Phaseolinae subtribe. Phaseolus and Vigna are the best represented genera with respectively 41 species (712 accessions) and 67 species (978 accessions). The collection also includes material of 24 other genera, e.g. Centrosema, Lablab, Macroptilium, Macrotyloma, ... The largest number of accessions are wild or weedy material, originating from 92 countries. Original accessions are entered into the Collection through exchange or gift.
Seeds for conservation and distribution are collected from plants cultivated in glasshouses of the Garden. They are dried at 15°C and 15% relative humidity to equilibrium moisture constant (5%) and afterwards stored in hermetically sealed packages at -20°C. Small seed samples can be obtained.

The database PHASEO is being developed in order to facilitate the management of the collection. The software used is "Progress", a fourth generation relational database management system. The structure allows users to avoid redundancy and to assure the integrity of the information. Programmes are developed with a multi-user-friendly approach. The database holds a wide-range of information about accessions that are, or have been, cultivated at the Garden. The data presented in the following pages are reported from PHASEO and concern the scientific name, accession number (NI), provenance and source (click here for details).
