The collection of barley autotetraploids described in former issues of BGN is maintained at the Giessen Field Experiment Station of our institute. The whole set of stocks, i.e. autotetraploids (4n) and corresponding diploid (2n) progenitors (if available) have been sown in the field in spring 2000 (Table 1). Authors of autotetraploids are given in brackets. Collected field data will be reported in the coming issue of BGN. New seeds have been harvested from most of the stocks as indicated by “+”. Limited seed samples of these stocks are available for distribution (Table 1).
