Sugar beets and related wild species – from collecting to utilisation

The IDBB2629 points to the most original sample (MOS) as recorded in the
IDBB (FORD-LLOYD et al. 2001)
tion and evaluation data as well as narratives, pictures and mapped collection sites of
individual accessions.
The IDBB provides passport data online via ZADI/IBV and more recently a downloadable
IDBB module containing evaluation data and passport data linked with them
(http://www.fal.de/bgrc/eu9542).
The access to useful accessions can be facilitated by rationalising collections and by
creating core collections. It is generally assumed that germplasm holdings contain
too much redundant material that decreases the chance of detecting useful genes in
unique accessions hidden in the bulk. Within the EU project “Evaluation and enhancement
of Beta collection for extensification of agriculture – GENRES CT95-42)”
probable duplicates have been determined in the world Beta holding based on similar
sounding names (FRESE and HINTUM 1989). In total 350 accessions sorted into duplicate
groups were ordered from partner genebanks, grown in the field for visual inspection
and morphological comparison. A second seed lot of each was sent to the
University of Birmingham, School of Bioscience, where AFLP and SSR analysis were
