IV. 13. Coordinator's Report: Autotetraploid.

W. Friedt, D-8059 Grünbach, Abt. Pflanzengenetik, Federal Republic of Germany.

The collection of autotetraploid barley stocks has been maintained as reported in previous years (see BGN 1, 1971; BGN 4, 1974; BGN 6, 1976; BGN 7, 1977; BGN 8, 1978; BGN 9, 1979).

In 1979, three new autotetraploid stocks have been added to the collection:
(1) KARRI 4x + 2x (V)   Spring barley (2-rowed)
(2) HA 2-1 4x (v)          provided by H. Ahokas,

(3) PGR-8480 4x  Winter barley (6-rowed) provided by G. Fedak

The whole collection is going to be grown again in the nursery at Grünbach in 1980. After multiplication, seed samples of all stocks will be transferred to the "German Genebank":
