The germplasm collections


The Gene Bank
The Centre has a large collection of barley, oat and triticale germplasm. Furthermore, several barley mapping populations are preserved (Nure x Tremois, L94 x Vada, Steptoe x Morex, Proctor x Nudinka, OWB-Dom x OWB-Rec, Arta x H. spontaneum, Mirco x Thibaut), together with introgression and substitution lines.

The barley mutant collection
The collection of photosynthetic and morphological barley mutants is continually enriched with new variants. Currently, the collection hosts 170 morphological mutants, 105 double mutants, introgression and sister lines obtained from crosses between wt and some mutant genotypes.

Morphological mutants are characterized by a deviation from the metameric scheme of the barley plant, based on the phytomer that leads to a reduction/addition of organs or the transfer of characteristics from a specific region to another (homeotic mutants). These phenomena have been found in the stalk, leaves, spike, spikelet and kernel. Studies are underway to map several mutant on barley genome, and some mutants which carry traits with potential agronomic value (e.g. leafy lemma - lel) have been used for the development of genetic material for studying the phenotypic-productive effect of the mutation.

Furthermore the Centre has a collection of barley chloroplast mutants, most of which are genetically and biochemically characterized. Albina and xantha mutants represent a ideal tool to investigate chloroplast development and its relation with other cellular pathways, while the viridis mutants, devoid of photosystem PSI or PSII, provide an opportunity to investigate the mechanisms activated in response to variation of excitation energy due to environmental stress.
