Abstract

The study tests collections of a traditional variety of Moroccan barley (Hordeum vulgare ssp. vulgare) conserved ‘ex situ’ to show differences in qualitative and quantitative resistance to an endemic fungal pathogen. Seeds from agricultural species are typically collected and stored in institutional seed banks, or ‘ex situ’ conservation. Plant geneticists have proposed that the dynamic conservation of crop plants in farm environments (in situ conservation) may help ensure adaptation to changing conditions. Results show some significant differences between in situ and ex situ conserved collections from the same localities. However, the small number of differences for qualitative resistance was unexpected.
