1 Agricultural Research Department, Danish Atomic Energy Commission, Research Establishment Risø, DK-4000 Roskilde, Denmark

BSMV infection caused a pronounced increase in the frequency of triploid and aneuploid seeds in eleven barley varieties, but with considerable variation in frequency among varieties. In some of the varieties triploids exceeded three per cent. In virus-free material a few triploids were found in most of the varieties, but the frequency was very low. There was, however, a significant variation among varieties.
