A LOW-COST METHOD FOR THE DETECTION OF DUPLICATE HOLDINGS AMONG GENEBANK ACCESSIONS

A set of 185 pairs of accessions with the same name from the Russian and Nordic collections of barley were grown in the field in Pushkin and were scored by the same person using a set of morphological descriptors. No differences were detected in the majority of the pairs (63%).In four out of six pairs no differences were detected for any of the agro-botanical characters. The accessions are most likely duplicates. In 13% of the pairs, the accessions were probably distinct and another 24% fell in-between these categories and required further investigation. Simple screening can reduce the number of duplicates. [The work is dedicated to Sergey M. Alexanian, Vice Director for Foreign Relations of VIR, who passed away in 2014]

Report of a Working Group on Barley: Seventh meeting, 10-12 May 2011, Nicosia, Cyprus

The seventh meeting of the ECPGR Barley Working Group (WG), organized in collaboration with the Agricultural Research Institute (ARI) of Cyprus, was held from 10 to 12 May 2011 in Nicosia, bringing together 24 members, 3 observers and the ECPGR Coordinator. The meeting covered a wide range of topics: implementation of “A European Genebank Integrated System” (AEGIS) by the Barley WG (approaches and aims for the European Barley Collection; criteria for Most Appropriate Accessions; quality standards criteria; species-specific maintenance protocols for wild Hordeum species as part of the AEGIS Quality System); precise genetic stocks of barley; collection of developmental mutants of barley and their potential use in pre breeding work; Trust multiplication project for cereals and legumes; characterization and evaluation (pre-breeding workshop and activities, ring tests update, breeding for climate change); in situ and on-farm activities in barley (Hordeum wild species in Europe, crop wild relatives of cultivated barley, conservation strategy for wild Hordeum species); documentation and information (the European Barley Database and EURISCO; the International Barley Core Collection); pre-breeding and joint research proposals (development of a disease resistance database; development of phenotype tests for abiotic stress resistance; evaluation of germplasm through ring tests; lobbying for pre-breeding at EU and national level; collaboration for joint project proposals; sharing of information and expertise)

PROTEIN MARKERS, MORPHOLOGICAL AND BREEDING-ORIENTED CHARACTERS IN DUPLICATE ACCESSION IDENTIFICATION IN THE VIR (RUSSIA) AND NORDGEN (SWEDEN) CULTIVATED OAT COLLECTIONS

Methods for identification of duplicate accessions in genebanks and the term “duplicate accession” are discussed. The results of comparative field and laboratory analysis of 112 pairs of potential duplicate accessions from the oat collections of VIR and NordGen are presented. The revealed conformity between the results of the field and laboratory tests proves the use of avenin electrophoretic banding patterns for duplicate identification in the oat collections before field testing or in case of loss of germination in the seeds of the tested accessions
